I don't recommend after market cats on these cars.
We could always go with E-85 and the long tubes and off road exhaust!
No fumes, different fuel.
No aftermarket cats because of a tuning issue(position, cat protection) or due to possible failure under high hp? Or both?
About to pull the trigger myself!
Van, when do you see it as beneficial to step up to the 2" primary and how much more of a pain does it make them to install to go to the 2" over the 1 7/8? I only want to do this one time so I want to make sure I order what will fit my eventual goal. PM me if you'd like
If you're long term goal is over 1,000 RWHP I would recommend going with 2" Headers. Otherwise the 1 7/8th will work fine.

Will any performance loss be seen at the 7-800whp bolt on level with the bigger primary? And how much more difficult is install with the larger primary?
