Hi Nick,
some years ago I made my own 2.5" Dual Glasspack mufflers. I used it for a while with a 1.75" header on an 2176cc engine and then tried it on my current 2789cc oxyboxer, first with a 2" header and soon after with a CSP/JPM WASP Stage 2 header. I think it looked very good and was not very restricted BUT it was extremely loud so I changed it in favour of a WASP Stage 2 muffler which is obviously even less restrictive and a lot quieter.

Hi Tobi
Very nice
I was looking at the JPM stage 2 but I'm going to get one custom made.
My engine builder has recommended someone.
I ran a 3" magnaflow turbo muffler on my 2276 and I want something with less noise and a deeper note.
Cheers, Nick
