I have a 2008 R32 exhaust that's been Tampavw modded (replaced the stock resonator with a Magnaflow 14156 race resonator). I also replaced the tips with 4" Magnaflow (part number 35127) polished tips.
It is pretty quiet under idle and low load (even with the flapper disconnected), with no drone, but definitely sounds great when you open the throttle.
I spent $350 in parts and labor just 2 months ago putting this together. I'd sell the whole setup for $300.
Obviously, I'd prefer a local sale, but I'll meet you halfway on shipping costs from Minneapolis. Or, I'd drive up to 50 miles to meet.
