Damn that is mean sounding. How loud is it at idle ?
I want to do it but I don't want to lose my low noise at idle.

Sounds great. Did you piece it together yourself or have a shop do it? There's a good custom shop near me and I'm debating having this done, they're great with trucks and have lots of magnaflow in stock.

I like sound of it ;)

I had a shop do it for me. My cat was dead so I opted for a magnaflow high flow cat and mufflers and removed the resonator. at idle its quiet and mellow nice low rumble. my friend says it sounds like a 5.0 when im driving but I doubt it its more like a 90s lambo when im gunning it especially when its shifting close to 6000 rpm.
