Choosing the right exhaust help needed.

Why do you want to dump it in front of the axle. I wouldn't recommend that for a lot of reasons. Run it to the back.

I run 3" with Borla XR-1 mufflers.
Didn't think I had enough room to run 3" out the back so hell yea it will be out the back.
How loud are your Borla XR-1's
