Just got my magnaflow dual in dual out in from summit, curious on how it's gonna sound. Planning on running true dual to the muffler no cats with turn downs. It's 2.5"inlet/ outlet with 11" case. Can't wait. It's got to sound better than the single in/out 10 series flow that's on it now with (most likely) clogged cats.

 

It might be a tad raspy and have some drone if you go catless, just so you know.

I have a single exhaust with a 3in/3out magnaflow with no cats and had to buy a resonator to get rid of the drone/rasp.

 

Its gonna be loud! Ive got long tubes, catless y-pipe, and just a single 2.5" bullet race muffler and its almost like open headers when i go WFO!
