I am probably the worse DIY'er here on the forum, and I did this mod in about 20 minutes flat. The hardest part was removing one of the rubber rings on each side.

It's surprisingly quiet, so I am thinking about removing the resonators as well, and throwin some straight through muffs in there...

Does anyone here have the quad exhaust tips (two per side) on their LS? I really want some good looking tips....

 

also, if anyone if curious as to what is sounds like... i can shoot a video of it whenever this crappy weather clears up.

 

if ur trying to line it up with the bumper ul hafta cut it since the OEM cutouts are tiny.

 

Wow, how many threads on this now?

 

Bout a million. Maybe two!

despite the way it looks, I went ahead and did it yesterday myself. I don't like the exhaust just hanging there of course, I'll have to do something different with it, but for now it does sound a lot better. No difference whatsoever driving though, its just somebody's 'butt-dyno' getting the best of them when they say the car's going faster. I've opened up my intake too, so I sort of expected a difference. Still, I found the sound I want!
