Hey, the time comes again when i am looking to do something to my 9k :lol: Right now I am considering replacing my middle muffler with a straight pipe. I know someone who will do the job well, so i am not worried about that. I am mainly worried about my car sounding like crap since it is a n/a. Has anyone with a n/a 9000 done this and do you think this would be a good or bad thing to do and why. I know this is hard to compare soundwise, i just want a little increase in sound without having to wake up the whole neighborhood with my car sounding like a ricer with a coffee can. :nono; Thanks

a friend of mine messed around with the exhaust on his 9000 (all be it a turbo) he removed the rear muffler, too noisy, so he fitted a smaller one in its place, too noisy, so he put the origianal one back and removed the centre muffler, too noisy, so he put a smaller one in its place, too noisy, so he put it all back how it should be, he's happy again :roll:

Sounds like me at 17 tinkering with a PC.

Most mature drivers I know have come to the conclusion Boxman makes; the middle resonator is there for a purpose, and that is to make the noise level comfortable. Best to play with design styles to get varoius sounds, but not outright loud. Saab specialist parts do work best for exhausts, as they were designed for this application.

I once read that the middle muffler was strategically sized and placed so as to make successive sound pulses cancel each other out and thus make things quieter.

When I replaced the OEM exhaust system on my Aero with a JT 3" downpipe and exhaust, the "middle" muffler was now positioned much further back, and the cabin noise became almost uncomfortably loud.

Can anyone tell me - if I re-position this muffler back in the middle to try and cut down cabin noise, am I going to have other problems?
