I was wondering if the 1 7/8" QTPs would give more HP in the long run with heads, cam, nitrous, and a complete biuld up on the LS1, than the hooker LT 1 3/4" Thanks.

 

THe headers that Thunder Racing and QTP sells are the EXACT SAME pieces. Made by a company in Mass. This company is the same EXACT company that has been making those same EXACT headers for decades for Roger Grotyohann.

So, if you buy them from Thunder or QTP you will have the original Grot LT headers. I got mine from Thunder 4 weeks ago (there sweet as hell) and has them installed. They are the best headers made for high HP motors.

his topic says"hooker vs..." hooker ls1 headers aren't made by the same company. The company that makes the QTP or the grotts are the best, in my opinion.
