Don't do my mistake .. go with 1 7/8" LT all day (+28 rwhp / +24 rwtq )
Hi guys
I know you have asked and read about 1 3/4" vs 1 7/8", absolutely you have seen people say go with 1 3/4" and some 1 7/8" ! .. Also some claim that the 1 7/8" headers will lower your torque !
I was having Pacesetter 1 3/4" LTs with their Y-Pipe for years, I dyno'd my H/C 346 with them and the result was 407 rwhp / 387 rwtq
Decided to try the TSP 1 7/8" headers with their nice merge O/R Y-Pipe and the result was 435 rwhp / 411 rwtq ..
So that's 28 rwhp & 24 rwtq more ! .. my tuner will send me the dyno graph by tomorrow

Yes same dyno, a week difference between each run ..
I know the gain is high from headers and Y-Pipe and you may not see it as high as this with bolt-ons car , but H/C cars with bigger intake and compression around 11:4 will shine the result more and more
