I have Dynomax Ultraflos on my car now. Nice deep rumble they sound good I kinda wish they were a bit louder.

I've spent hours on YouTube and my favorite sound is the Borla XR1's but they aren't offset so would need to do something more custom. I've debated the Black Widow mufflers... look them up.
WOW...just listened to a youtube clip on Black Widow mufflers...has the throaty sound I like!!
