Who makes the best mid-length headers?
Not too many have tried the Bassani’s with an ORY so there aren’t that many dyno gains info about them like for macs, but most of the dynos that I’ve seen with cats have shown the Bassani’s to gain about 10 to 15 rwhp through cats on a stock internal motor. Bassani uses garbage cats though (Catco), so if you do want to run cats I would recommend getting the ORY and welding in some good cats like RTs or CSs.
I plan to get Bassani's eventually...
