Muffler options ?....

Rob, you want quote in the cabin?
Best flowing turbo muffler is a dyno max turbo. Fit the longest one you can. The tti web site has a list number next to there diagrams you can cross ref at summit. Slip a 2-1/2 pipe into a 3 inch muffler. Tail pipes!!!

Borla is a straight through glass pack type of muffler. Those and the Hooker Max Flow or the Dyno Max max flow are the same and flow the most. Period.

The Hooker Aero Chambers are the best flowing “chambered” muffler. A pair of 2-1/2 inch aero chambers are only good for about 300 hp.
