Borla XR-1!!! Awesome Sound!

 

I have not heard the aero turbine. But I swithced from a magnaflow to a borla xr-1 2 weeks ago. All I can say is wow what pleasant difference.

 

are u guys just running headers, off road y-pipe, into the xr-1 ???? doesnt it sound too raspy ??? im looking to put an xr-1 12" oval, but not sure if i need to get a dynomax bullet to put before the muffler to help with the raspyness or just go with a 16" oval xr-1
