I have a 90 Notch that is ready for exhaust and I want to run tailpipes even though it is going to be a 900ish hp car. I was trying to avoid full custom. Looking at using a flowmaster 3 inch tail pipes kit. 3.5 inch pipe and mufflers. Has anyone had this setup or know where to look? I was either going to use a reduced x pipe (3.5 front, 3 inch rear) and run 3 inch mufflers, or 3.5 inch x and reducer for the muffler. Has anyone used the 3 inch flowmaster tail kit with big power? Thanks very much for help
Yeah. 3 1/2 is important through the mid pipe. Tails don’t matter too much I’ve been told. Problem I’m having is trying to figure out what to do to reduce it from 3 1/2 to 3
I make over 900hp and if it helps I run 2.5" starting at the firewall through a pair of Ultraflows and a third X-muffler I designed and made myself. IMO, 3" isn't needed if you're concerned about space.
