Default Loudest, Deepest Exhaust

Is the Ford Racing Exhaust on the 2007 Shelby GT similar or equivalent to a product that Borla sells?

I am currently running factory headers, factory X-Pipe with the Cats out, and factory Axle-Back Ford Racing Exhaust.

It sounds good, but I want to install some mufflers that will make it incredibly loud, but still sound good and deep. I used to have catless dumps under my Mach 1 and am used to alot louder exhaust. Any ideas?

Thank you!

KR mufflers.
they sound great and get loud when you step on it.
perfect for a Shelby. but cost a pretty penny.
then again, you dont want a set of cheap mufflers on a Shelby, do ya?

Also pick up KR h pipe from Shelby ... Definitely deepens the note ... It's a small piece that is weld in place of x pipe section

I am running Dynomax UltraFlows on my car and I have had several comments about how deep the tone is. I do run an O/R Xpipe, but they are a very good sounding muffler IMO.

i would go with either an o/r or high-flow catted h and the borlas or custom macs.... i had the borla aggressives on my gt and I got many compliments on them...

Here is my set-up... I'll be adding longtubes and probably an o/r x or h soon as well..

MRT - catted H and custom macs

Roush axle backs with factory cats and h pipe work perfect for me.
