I've just read the "let's talk exhaust thread." Has anyone ever put the borla xr-1 muffler on and ran a single 3" tailpipe in the stock location? What about the magnaflow installed the same? Gonna do something this week. I like the no tailpipe look but just trying to keep down cab noise. So for the final decision which muffler? And which part #? Please comment!!! Looking to order muffler Monday or Tuesday.

Thanks,Jeremy

 

thats the one i have the xr1 3 inch

 

same here. just have mine dumped.

 

i have mine dumped and sounded bad *** with my cam..i just installed my stall and ran it behind the tire and it dont sound as loud anymore but im not sure to dump it i dont want the loud noise inside the truck

 

Are ya'll running the xr-1 12" long or 16" long muffler?

 

the 12'' with the dump there is a bit more noise in the cab but not really bad imo.

 

xr-1, or just about any performance muffler gets very vocal when you add LT & ORY. If those are in your future, you might want to run it out back. I'm going back to a stock muffler dumped and E-cutout this week.

 

Thanks

 

I have a 3" XR-1 exiting before the rear tire. Cab noise is minimal but once you get on it, it does sound like sex!!

BTW, All else is stock on my truck

 

Did you guys just buy the muffler and repalced the stock one or the complete catback system? Does anybody have a model numebr for the one for our trucks?
