this is why TTi headers suck for power

Stepped headers are a compromise. This is a known. Now it's shown.
Oh, almost forgot, DLI even complanes about tubes being to long on OOTB headers. That in itself should be telling you something.

Good notes DGC333

The w-2 headers weren't stepped. It's 1 7/8 from the flange.

bla bla bla.. all i know is my car runs better with the tti's then it did with the headmans... different combos require different headders.. big deal.. i do know i have yet to scrape my tti's on the street, yet to burn a plug wire on #5 or #7 cyl., can get #5 and #7 plugs out with eas even when the motor is hot. can get my starter out with no problem and don't hvae aby leaks.... so i'll keep my tti's.

Yes, Joe on our 400hp rides it doesn't make much of a difference and teh headers are a big step up from stock as well. The cheap hedmans suck as well, along with most of the crappy fitting small tube headers.

This is the second engine that has shown a 30hp increase from changing from TTi's to either Hooker SC or Hedman race headers. The first was a 394 now this 416.
