Title: looking for a good exhaust with minimum noise Post by: wolfswest on July 11, 2008, 07:56:46 am Hi guys,
I have the same exhaust as in the picture. Thx to Jesse DVK for letting me “borrow” this picture… :D Now, this exhaust is a real beauty for the money you pay for it, but it screams a very high tone sound…. >:( >:( I can barely stand it no longer so I’m thinking to install something else… What are the suggestions? I was thinking of a dual quiet pack or something like that. Are these less noisy? AND the most important question, will I loose HP? I don’t want to loose HP… ;D Some specs of the engine: It’s a 2179cc with ida’s producing around 190hp with the fanbelt of… Thx, Dem Title: Re: looking for a good exhaust with minimum noise Post by: streetvw on July 11, 2008, 08:12:13 am twin quiet packs aren't to loud and they look sooooo cool

Are there different quiet packs on the market? brands, sizes...?
Title: Re: looking for a good exhaust with minimum noise Post by: streetvw on July 11, 2008, 08:32:55 am yeah there are quite a few different ones about the one on the car above was a pheonix one mounted on a Berg 1.5" street header, but S&S and bugpack also make them I'm sure. you could always cut the mounting flange off and weld it back on once you have the muffler sitting in the right position?
Title: Re: looking for a good exhaust with minimum noise Post by: Neil Davies on July 11, 2008, 08:54:55 am I had the Bugpack dual QPs on my Ghia on an old merged header that I was told was a Berg one. Needed to cut the flange off and re-weld it but not a major job. :)
Title: Re: looking for a good exhaust with minimum noise Post by: wolfswest on July 11, 2008, 08:56:27 am yeah, the flenge will be a problem I think. I can't weld myself so I have to search somebody who can help me... we shall see. First I want some reactions about the HP... :D
Title: Re: looking for a good exhaust with minimum noise Post by: streetvw on July 11, 2008, 09:04:15 am I seem to recall the hotvw's dyno test showed that dual QP's didn't affect HP in most applications, perhaps Deano can remember as it was his article.

That would be a good thing... let's see for some reactions... Title: Re: looking for a good exhaust with minimum noise Post by: Rennsurfer on July 11, 2008, 09:58:34 am I can't stand my cars to have a loud exhaust note. I was very pleased after installing the system that I had Tiger at A-1 Muffler build for me. It includes 1½" diameter heater boxes, the same sized sidewinder merged collector header, and a Magnaflow stainless steel muffler. I forget which size inlet and outlet we decided on. Anyway, it's not too loud and works excellent. I made mine even quieter by adding a custom outlet piece that exits out of the factory apron cut-outs. Not everyone wants that look, but I'm sure that you could come up with something different, if you're so inclined. Personally, I wanted maximum ground clearance and I've already had all of the FourTuned and S&S systems back in the '80s. This time, went for a completely different look.
Here it is after I painted it all. I ended up changing the muffler inlet & the muffler backside from silver to black. Looked better than what's pictured here. (http://i271.photobucket.com/albums/jj128/Rennsurfer/NewExhaust50807.jpg) After installation. (http://images.thesamba.com/vw/gallery/pix/454562.jpg) That's just one option that A-1 Muffler offers. Call Tiger and I'm sure that you can come up with something that's both quiet and performs well. Their phone number is (714) 836-7201. Tell him Mark from D.K.K. (with the Zenith Blue '67 Beetle) sent ya. Good luck with whatever you end up using.

Will a dual quiet pack in question look good under my car?
Title: Re: looking for a good exhaust with minimum noise Post by: streetvw on July 11, 2008, 11:11:40 am the car in question... Will a dual quiet pack in question look good under my car? to right it would look cool! 8) a period exhaust on a cal looker is there anything that looks better? Title: Re: looking for a good exhaust with minimum noise Post by: lowfastbus on July 11, 2008, 11:34:15 am I would go for a double quiet pack, not to much noise except when you're in high revs.
Never noticed a loose off hp... with them on my car.

Jelle Jelle, I think you have the same header as mine. Did you ever drove an exhaust like mine now or something similar? Did you need to do some welding on the flenge when you installed the dual quiet pack? If so, can you help me out? Title: Re: looking for a good exhaust with minimum noise Post by: Glauco on July 11, 2008, 13:05:14 pm yeah, the flenge will be a problem I think.

First I want some reactions about the HP... :D I'll weld them for you, duall quit pack all the way man ;)Title: Re: looking for a good exhaust with minimum noise Post by: wolfswest on July 11, 2008, 18:31:10 pm I went to the local vw shop this evening and Steve barrowed me a dual quiet pack to see if it suits my needs. I removed the exhaust and tried to put the dual muffler on... WTF... I hope there are different models because this one hangs completely after the car. not a single inch is tucked away under the fenders... ??? So I hope there are more models or else I have to do some serious welding and that is not possible on a barrowed exhaust...
He also told me that there will be hp loss >:( :-\ I will post pictures tomorrow so my explination makes sense... Title: Re: looking for a good exhaust with minimum noise Post by: roland on July 11, 2008, 18:36:30 pm I guess he gave you a dual qp not for merged header...
Title: Re: looking for a good exhaust with minimum noise Post by: wolfswest on July 11, 2008, 18:45:56 pm I guess he gave you a dual qp not for merged header... that's right Roland, I allready did my homework and there are two models, see the pictures. I received the wrong one. In the webshop his description they say with the "good model" "competition dual quiet pack" So is this just to know that it is for a merged header or is also the diameter of the flenge bigger? Who can tell? Because the model I have right know the flenge is much smaller then my header.... :-\ So I hope it is different with the good model.

Title: Re: looking for a good exhaust with minimum noise Post by: nicolas on July 11, 2008, 19:22:41 pm ask Tobi DFL he has the same engine, lots of power and runs dual quietpacks. now stop going to Steve and let him work on my engine!!!! ;D ;D ;D ;D

So we talked about an hour or 2 and then he called it a day. Normally your engine should been ready this night but it turned out different....

Title: Re: looking for a good exhaust with minimum noise Post by: Rennsurfer on July 11, 2008, 20:48:44 pm Mark, Can you tell if the flenge is bigger inside then the "standard" model? I'm probably not the right person to ask, but if I remember correctly... there are only two flange sizes. The larger Thunderbird one and the more common smaller ones like on (S&S, FourTuned, A-1, etc. What you need to be more concerned with is the position of the flange. Looking at the Fatboy muffler that you posted, it looks like a small flange is on that one. Which is good. The only issue you'll have to deal with is pointing the flange to the correct position to line up with your header. A very easy fix (if that's the problem) for someone that can weld or simply take it to a muffler shop. Inexpensive, too. Without seeing your header and muffler together, it's rather hard to tell, just from pictures. But with a merged collector, you do need the added bend on the muffler inlet(s). That much is factual.

I had a A1 muffler on before... never noticed a difference; best time on the strip 13.5 with double quiet pack ; 13.6 with A1 muffler I changed the flange on the double quiet pack for a bigger version.

Or can I pay you to do it? ;D Title: Re: looking for a good exhaust with minimum noise Post by: lowfastbus on July 14, 2008, 21:04:28 pm It's a bugpack with a bigger bugpack flange, bot ordered through Steve, but can be get anywhere.
I like the Flat4 ones too... would love to seen one off those on a car. If you need help, just mail me... Jelle Title: Re: looking for a good exhaust with minimum noise Post by: Critter1 on July 15, 2008, 04:44:26 am Here is what I put together for my Fastback with 1968cc. Its a 2" Magnaflow. I can't recall the exact deminsions, but its one of thier smaller mufflers. Its hooked up to an older S&S 1-1/2" merged header. It sounds great with a nice tone. I'm impressed with it.

Title: Re: looking for a good exhaust with minimum noise Post by: Torben Alstrup on July 15, 2008, 19:20:54 pm Hello. One note toke take into consideration.
Most dual quietpacks wohnt handle more than about 160 hp. After that they begin to limit the output. T Title: Re: looking for a good exhaust with minimum noise Post by: Jim Ratto on July 18, 2008, 21:41:02 pm With that big of a motor i would be concerned about it running hot with dual quiets. My car ran so much cooler when I uncorked it, thanks to Bill Schwimmer's advice (2165cc) and swapped QPs for Magnaflow.
Yes it is loud, but personally I like the aggressive bark it gives. What about a Dynomax turbo muffler, they are much muh queiter than the Magnaflow, but still run well on big cc engines. I know lots of cars that went 13's at near 100mph running QP mufflers, so they will work, but not as well as (cooling) as the larger muffler.

Jim, Yesterday I took my bug out for a spin with dual quiet pack mufflers (small flange) and after a while I saw some heatmarks on the cooling thin so yes, it's a fact. The engine runs much warmer with the qp's then a turbo muffler. Maybe this has something to do with the small flange? If I change it for a bigger flange + a bigger tube between the flange and the part where the qp goes in 2 pieces? Dem Title: Re: looking for a good exhaust with minimum noise Post by: Peter on July 19, 2008, 12:06:55 pm hey Dem,
i think the flange may have something to do with it, but the mufflers itself are restrictive as well... Title: Re: looking for a good exhaust with minimum noise Post by: wolfswest on July 19, 2008, 21:18:53 pm hey Dem, i think the flange may have something to do with it, but the mufflers itself are restrictive as well... Peter, Yes, I worked all day on the car and installed the old turbo style muffler back under the car. the power output is so much better, so I guess I will stick with it. Maybe I work out a modified dual qp like Tobi's this winter because I like the look, but for now I will stick with the current system. But I noticed when I watched in the muffler that there was no wool in it. I'm gonna cut open the muffler and put special exhaust wool in it from a motorcycle and weld it again. So I think that it will be more quiet... Fingers crossed. I will post pictures of the works... How is your 2276 developing? Title: Re: looking for a good exhaust with minimum noise Post by: wolfswest on July 25, 2008, 10:38:18 am a little update... maybe interesting for all you guys that drive the same exhaust as shown in the picture... Me and a friend cutted a square in the muffler on the bottom end and filled it with some sort of wool of a motorcycle muffler. Besides the tube with holes in it there was NOTHING is this muffler... ??? I guess more expensive models from A1 and dynomax etc have something more inside... (pictures will follow to make it cristal clear) weld it back together and took it for a spin yesterday...
WOW, impressive! :o At idle and midrange rpm's the sound is deeper and when I hit the high revs it sounds more like a factory racecar, not like a screamer... The car is certainly more quiet and I'm satisfied! And the most important part of the story, just like I expected: It makes 'more' power.... Torque builds up quicker in midrange rpm's... When I shift in tihirth normally I have a little dip, no torque, no hp, but now he just pulls trough this dip more faster and hits the powerband faster... the dip is gone. Probably you won't see this on the dyno but you just feel it.... tonight my friend's vette is going down... ;D Dr. Bad Dem Title: Re: looking for a good exhaust with minimum noise Post by: Rennsurfer on July 25, 2008, 15:44:20 pm Right on! Sounds like you achieved your mission. Hopefully, the 'Vette will go down. Always a good thing when an air-cooled VW takes down and fully embarrasses a V8.
