Quote: the headers that Ryan dyno'ed TTI had 3" collector and the husler had 3 1/2" collector. I have the 1 7/8 TTI with the 3" collector and I think the collector is alittle short for making power. also when looking up inside the collector I notice where the 4 tubes come together,their all different lengths. any other header collector i'v looked in have all been same length.
From the website it looks like they only come with 3.5" collectors now...I am only running a 3" exhaust though, so I would have to get an adapter to neck them down to fit everything else.
