i just saw stone mountain racing stainless headers/ypipe polished with gaskets going for 290 shipped...they sound like a steal considering a ypipe is around 290-310 shipped intalled with gaskets...my question is who the hell is stone mountain racing...hows there fitment..any bee's in can?...anybody got them?...arethey worth it or should i just go with the warpspeed and throw 40 into my pocket?
i think i might jump on them since im only paying 40 dollars extra for the polished headers and maybe 5 extra horses(or not?) any thoughts?
"THIS SUPER STAINLESS SETUP HAS ALSO THE CORRECT
O2 BUNGS ON THE Y-PIPE
42MM DIAMETER TUBING ( NOT 38MM LIKE " OTHERS " )[ the company is comparing them to obx which is **** from what i have read]
STAINLESS PRIMARIES
HUGE GAIN FROM THE Y PIPE ALONE
3/8TH FLANGES
TIG WELDS" Their claim.

I remember that, and you sure did catch some heat for that. Interesting thread however

What makes me think they may not help us (bigger piping) is this car runs 11's NA and has 260hp dont know if its whp sounds like it.
But ill still be purchasing the headersin the future to put on my 3.5 which will be reving at least to 7500rpm and have big juicy cams i will have a dyno without headers in a few weeks when i get the car back.
So when i put headers on i will see how they gain with that setup .
