hey i would like to install electric cut outs, on my 03 yukon denali. unfortunately i have the dual exhaust pipes, and my muffler is a dual in single out. Im assuming that i would need to cutouts (2.5" right?) and that i would mount them behind the rear o2 sensors and in front of my muffler correct?

P.S. My muffler is a flowmaster 50 series dual 2.5" inch in and a single 3" out, the muffler shop that did it slid a piece of 2.5" piping in the 3" coupling then welded it shut. Do i have some hard core back pressure or does it not really matter having, 2 2.5's in and one 2.5 out...thanks

 

So they put a 2.5 pipe after the muffler and attached it to the rest of your exhaust? Honestly that does not sound ideal, especially for a 6L....

 

word on the 2.5" with a 6.0...

Ditch your setup, run an ORY with some different muffs (ill let you hear my Hooker sometime), then a single Ecut out

 

i have turn downs, so it is 2 2.5's in and 1 2.5 out welded to the inside of a 3" outlet then bent down. Honestly i dont know if i would have room for an ory and a muffler, nor do i know if i would want to spend the money. I like my muffler and it suites me. I was just wondering if the cutout goes after the rear o2 sensor, and if that 2.5 out is ******* me up, cause if it is i will take it back to the muffler shop and make them fix it
