As far as the exhaust goes, when we got her up on the lift at the muffler shop the stock system is very high quality- all stainless (not just aluminized) and mandrel bent from the looks of it. So I just wanted to replace that huge resonator. My shop happened to have some leftover stainless 2 1/2" pipe he cut to fit. I think he charged me $75. I drove it for a week but it sounded almost stock, too quiet. So the muffler was next. It is an odd beast, a single side inlet with a single exit on the same side, transverse mounted. The only low restriction unit I found that would fit is the Magnaflow 14210. Luckily it is all polished stainless steel, slightly shorter case than the factory muffler but the factory hangers can be encouraged to fit. The sound? Magnaflow promises a deep tone and they were right. Leaving the muff shop I was a little disappointed that it was still too quiet. However after a few miles you will definitely notice a nice deep note. After 10,000 miles on this I am very happy. It is not loud or "farty" but sounds just right for me-fairly quiet at part throttle but it gets more aggressive when you do. You do not need to buy an expensive "cat-back" system just replace the restrictive parts.
