Ok, because I bought TPs that are 2.25"
And I looked at my HR TPs and though, FUUUUUUCK... Those are bigger...
And if the Momentum headers have a 2.5" exhaust going to a 2.25" would make turbulence and you're choking it down
And my only solution is to either MAKE a HR flange and weld it to the headers, or MAKE a DE flange and weld it to my HR TPs
(I have a small window because the headers come in Friday and I gotta go weld it on my lunch, and Saturday I drive out to the dealer with my box of parts to install)
