Borla XR-1 muffler swap

[T4nkDr0id]

Had my shop cut the OEM muffler and weld in a Borla XR-1. Also had them slash cut the tip just past the axle and hi-temp black it for a cleaner look.

 

Startup vid (after a out 1,000 miles):

 

There's definitely some drone at around 1,700K, but it doesn't really bother me.

 

I'll try to get an in-cab driving video soon.

Did the same on my truck and left the tailpipe alone but my muffler is angled like yours because of the factory offset.  Used an XR1 oval though as opposed to the round.  Mine droned enough I couldn't stand it so I killed 2 birds at once.  Regeared the truck ith 4.56's so it runs now at 2100 rpm at 70 mph and it doesn't drone at all!  Win!

Nice! I'd like to re-gear, but not sure if I should and can't afford it right now.
