Greetings all, I was wondering what would be the best pully and tune combination for a GT40? Also what would be the be cat back system? With more power is there a need for clutch changes?

Thanks!

Heffner makes everything you need, pulley, tune and exhaust.

As far as the clutch, the twin turbo cars are running the stock clutch so a pulley won't bother it.

Have the Heffner pulley and tune, loving it.

Vast majority just stay with the stock clutch, no problem.

As for exhaust, that comes down to personal preference. There is a great video floating around here that shows about 4 or so of the popular options, you might be able to find it with a search.

It's a must do modification. Better sound, better flow, less weight, less heat, better looks.
