I need something like this but what I have found so far isn't even close.

Thanks in advance.

Chris

Looking really good Gustav! Now we will have 2 more wastegates marks on the floor in the dyno room Not to speak about the sound when the 2 opens Should be a nice hearing for the neighbours

looks great! but one question, why is the one dump tube going up and over the other when it looks like it could just go down? or is the subframe in the way?

Yes there was no room for it to go the same way.

gaaah... can't make up my mind whether to make a new 4" full exhaust or staying with my old 3".... feels wrong to stay 3" but i don't want to make my ears bleed more than they do when im out criusing..


What to do?

i've done a couple full 4" exhaust on bridgeports and it really wasn't that bad!

as long as there are no exhaust leaks and the muffler exit a little past the bumper it wont resonate and drone inside the car. Outside..... that's another story but who cares!?!?!?!! hahaha

What to do?
Yes, I agree that it seems wrong to choke the 4" down to 3". If you want to maintain the surface area of a 4" pipe without all the noise, consider running a pair of 3" pipes. The area will be slightly more so you'll have similar flow (or better), and the noise reduction will be better than you can achieve with a 4" pipe.

Did you polish that yourself or have it professionally done?

It looks great!
