looking for a good exhaust with minimum noise

[wolfswest]

nice things you can do if you are a bit handy...      I will look for a solution.

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...

I've looked at these models on the flat 4 site and they realy look good.  I was wondering what the price would be, anybody a clue?
I will contact you Jelle...  thx 4 helping me out.

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.

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?

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?

[wolfswest]

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!    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...

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.

yep,
Last time we did the 1/4 mile thing my front t-bar was equal with his rearbumper when we crossed the finish, a close race    I hope that I'm gonna catch him now...  it's also a tricked out vette, not stock...
