it's seems to be telling the me that you get a more sporty sound by doing this mod. The reason I say this is cause I have it done to my car and not much of a difference in sound from stock.

Are you sure your welder did it correctly then? This mod is supposed to allow a partial bypass of the exhaust from the cats straight to the tips of the muffler. You should have gotten a very noticeable increase in sound.

No, I did not do the mod myself, as I have a Dansk exhaust, but here is a video of the mod. He did also have the fabspeed cat bypass pipes installed, but you get the idea:

you should definitely feel the diff in sound, not so much performance.

ive been trying to this forever now, but cant seem to find anyone that can bend the pipe that small of a diameter.

its would be the same without the pipes if you were to just drill a hole in the pipes without connecting it to the tip(s)

do you think i should add the bypass pipes as well? Maybe that added to the sound. What do you think boxtaboy ?

Btw, although I haven't seen anyone do this yet, so can't confirm for sure, you don't need to actually run pipes all the way to the tips. You can just have them weld a smaller u-pipe that bypasses a baffle in the factory muffler. Here is a picture of the factory newer 2004+ Porsche Sports Exhaust (PSE), without the exterior sebring bypass pipes that the pre-04 PSEs have. The extra smaller u-pipe is in clear view. This is what provides the extra sound in the PSE.
