I came across somehting about QTP(Quick Time Performance) and the headers they have. The dont have actual truck headers out yet but will soon but what caught my eye was the 40rwhp gain on the LS1's just from header install. You can get either 1 3/4" or 1 7/8" and both have 3" collectors. Anyone have any experience with them ont he cars?

 

40 rwhp..... ....man thats ALOT. Id like to see some proof on that haha.

 

40 RWHP for just headers sounds like alot, are you sure it wasn't at the fly wheel?

 

rwhp-it was in add in last months GMHTP!

 

Questionable....25 more than any others...maybe they installed a Tornado and a gas line magnetizer,too

 

I would question that claim......Tell them if you dont get 30rwhp you are going to ship them back.....in pieces.

 

They have been "talking" about truck headers for over a year....I think if you do a search you'll see an old post by HitmanX. GMHP also claimed huge gains from Granatelli Motorsports MAF, plug wires, etc...which we all know have been proven to do jack ****. Be careful what you read and believe. Did you hear about the man with 5 penises....his pants fit like a glove.

I doubt its even 40 at hte flywheel. Thats like saying...Drop your spare out, then im sure you wont have ANY problems hangin with the f-bodys lol.

 

Well they are false advertising then. Straigt up! Its on one of the 1st 10 pages of GMHTP(2 issues ago). Its a ad not a write up! On their site they say they give 18hp over other LT's

But the add I saw said they will give 40rwhp on LS1's!!
