My questions is simple; has anyone removed their mufflers in favor of straight pipes? My local, neighborhood pipe-benders don't seem too interested in performing a mufflerectomy for me (sounds painful, but it isn't). However, in a previous VW Turbodieseled (TDi) life, I lopped off the muffler and found tremendous improvements in turbo response and boost pressure. The TDi does use a VNT (no BOV), so the overboost is just a reflection of the faster acceleration ramp of the turbo wheel, without the backpressure. I brought home a nice, metalic red MS6 a few days ago and I can't wait to get started on modding it. It's a great starting point, but there is definitely a distinct pressence of lag with the turbo. Would removing the mufflers reduce the lag? It works all over the turbodiesel world and I've known some WRX and Evo drivers who have done it. Anyone ventured there with an MS6?

I have my mufflers removed. I had a local shop unbolt the mufflers and add some pipes to extend the exaust back to the bumper. Cost me a case of beer and $20.00. The motor sounds much better(you can actually hear it running now!)--but I didn't notice a big performance improvment.

A search would have done you good... FYI
I removed my mufflers and installed resonator tips... purrs, bubbles like a small V8, if anyone can remember the TVR. And it has great mid range pull.

see, I'm not the only one that says lopped off. :p By the way I did it, but had them remove the cat, and replace w/a resinator, w/no mufflers it definately made a performance difference.

street concepts says their exhaust can be bought in sections. i think i might buy the pipes and not the mufflers and put on my own tips.
