4 pipe 1.75" exhaust extensions / tips - what are my options?
I'm looking for exhaust tips/extension for a four pipe system with 1-3/4" pipes which have the last couple inches turned down.
I have recently modified my exhaust hanger system which spread the 1, 3 and 2, 4 exhaust further out from the center and raised them.
It's hard to measure.. but I feel the cockpit is louder and I'd like to try exhaust extensions.
Any recommendations would be appreciated. Thanks!
