as title says, has anyone x piped and true duels on a ls1 car and stock manifolds?

i'm asking because i may be getting a m6 in the near future as a dd and am trying to gather money for my 1st mods before the purchase.

 

Probably not much more than a regular free-flowing catback.

 

yeah i'm not sure you'd really gain much at stock or basic bolt-on power levels. other than sound, the TDs don't really shine till higher hp levels.

 

12.835hp over stock catback

 

how does it sound on an ls1 car? i love the way it sounds on mine, but not sure what it would be like on a ls1. is it more of a high pitch 4.6 mustang sound?

 

Id let you listen to mine but I dont have a way to video or host... it sounds good though. think nice sounding LS1 catback only louder and from under the car and not behind it. my whole car shakes from the sound

 

You know you can just get a pair of Pacesetter long tubes for like $279 uncoated of course. But I really would not put an xpipe on a stock manifolds, It won't sound to bad, but the gains over a good cat back and clearance issues is not worth it unless you put LT's.

 

well with my lt1 car i didn't loose much clearance at all so i'm not worried about that, plus its cheaper than any cat-back and sounds better. i didn't know that headers were that cheap for the ls1, i'm afraid of the uncoated tho.
