"Final answer is our headers do not fit 6-spd transmissions without modification to the y-pipe." <<<< was from your post earlier in this thread. I'm confused...

Do your headers and y pipe fit 6.2, 6speed, 2wd transmissions with no modifications required? If there are modifications required can u post pictures? I am going to be purchasing your 1 7/8 headers and y pipe as soon as I find out wether or not I need to make an appt with my local exhaust shop

We installed a set of 1-7/8" on a 08 SCSB last week that we just swapped a 6l90e into and the y-pipe touched the tranny pan so we cut and reangled it slightly lower and welded back together (took 15 min) so it wouldnt rattle against the trans pan. BUT most trucks have 6l80e's which I think has more clearance as the 90e' only comes in work truck 2500hd's etc...
