Hey wstar, remember this pic from my header installation DIY thread, showing how the CBE doesn't line up with the HFCs after I installed the Stillen headers?

Do you think it's possible that you had that issue with the tips being too high because of this (considering you have the same headers/HFC setup)? What I'm envisioning is that the flange of the CBE came down in order to meet up with the HFC flange, which in turn tipped the rear of the exhaust upwards, thus making the tips touch (or almost touch) the rear valence. Does that make sense?

Yeah I remember that pic. Given your pic, the issue I just had with my exhaust tips, and the issues we all had with the Stillen CBE (it was low in the center and hitting the crossmember, but I think for the same reasons - it's just affected differently because it hangs differently), I'm pretty damn sure that Stillen Headers + Berk Cats = HFC outlets come out too low. What's not clear is which (or both) of those are at fault.

I'd say it's the headers, because I did the HFCs and CBE first, and everything lined up just fine. It wasn't until I subsequently did the headers that this alignment issue came up.

Had the same issue......but I think I may be the only one who agreed to have my HFC's shortened and welded back on. So far so good.....no issues to report and that was about 3 to 4 weeks ago.
