I've just ordered the ATLP V2 Quad Exhaust pipes for my 08 TL-S recently and just wanted to know what the performance gains is on it. I've read on another thread that it's suppose to be like 40 hp but not sure if that's with the j-pipe & resonator.

If anyone can tell me if there's any performance gains for just the pipes that would be great

 

Thats with other mods. Jpipe and catback prolly dont even make 40hp.

 

^+1

 

exhaust itself is about 10-15whp/tq +/- (from seeing other people's dyno)

 

Maybe like 8whp lol.... you could go and dyno and find out for yourself though... that would be most accurate lol

 

I have a 08 Base TL (Auto) with rv6 v3 PCDs, v3 jpipe, ATLP quads, Injen Cold air Intake and Hondata Flashpro tuned by Vit.

I would consider myself lucky if I gained 40WHP with those mods.

There's no way for me to tell because I never got my car dyno'd for a base line comparison. However I did get it dyno'd after all those mods and only made a measly 230WHP and 190TQ

 

I know you will gain 12 horse power easy. Tq i cant say.

 

I'd consider yourself lucky if you gained 10whp from a catback. Personally, I think most of the performance gain comes from weight loss. People probably claim it adds 40hp because they're feeling a combination of the weight loss + 10whp.

 

Very helpful guys, thanks
