Sweet sounds!! I had a Magnaflow Cat Back system on my 02 Dakota with a V8. Nice sounding but just a touch on the loud side. My wife kept asking what was wrong with my exhaust. I'd love to do it on my 04 Quad Cab.
Yep. Boxer 4s sound different than IL 4s. Nice growl. dBA and project write up will be sorta like the one I did for the FJR D&D cans (sound clips, meter readings, etc.).
I had a magnaflow system on the truck for years and never a problem. This kit is all ss with 3" pipes for better flow. Also deleted the resonator. A slight increase in total volume that got eq'd out by the recorder, but the detail page will address the differences (still within any legal numbers I've seen *under 95 dBA iirc).
