Off road Y-pipe - fits 00'+ LS1 f-bodies. It's a a congolmerate of: custom bent cat delete pipes, an SLP Y, and a Flowmaster Y junction. It will fit 98'-99' cars if you swap to 00'+ manifolds. I don't need it, just taking up space - come get it!

 

what did it do for you performance wise?

did it make it any louder without the cats?

the wife always complains her car is too quiet. i straight piped the diesel last week, and now she wants her louder again.

i'd need 02 simms for the rear o2's? right?

 

Hard to say what it did performance wise, never did any dynos, and changed more than deleting the cats at once. If I had to take a guess, I'd say no more than a tenth. It will definately be louder w/o cats, nothing insanely loud though. I have 02 SIMMS in my car, but you can do w/o them - there will just be an annoying SES light on the dash.

 

still have it ill talke it

 

I still have it, email me at Bz2886@aol.com for directions and to set up a time when you can drop by and get it.

 

If he doesn't get it I'll take it for my friends car. Just let me know, thanks!
