yeah i've had good and bad from them

yeah, 300whp 260wtq can be had on the 80mm and 93...but that takes a good tune so we shall see where i get it...

my first go around i had 250wtq on a **** tune and shoot header so should be interesting

 

Yeah both of us are going to see what ottps long tube header can really do. I'm going to be getting remote tuned by zrated89s tuner. Safe bet his tuner knows what he's doing lol.

 

yeah, i know the 3.35"m62 doesnt move enough air for the header and i lost bottom end, but we shall see what difference there is with header

 

I was 235whp and 230tq with gm stage 2 only. Now I have ls4 tb, zzp 3in intake, zzp stage 4 clutch and fidenza flywheel, 2.5 pulley on a ported m62, 60# injectors, I have hptuners, short header 1.750 runners to 3.25 collector to 3in exhaust all the way back.

 

and duel pass end plate. Nos. Soon to have the killer chiller in also.

 

So did I. And I totally agree, the more air you can ram into that header, the more it likes it.
