Perfect replacement for my rusty super turbo. Great sound for a Porsche 944. *** 18 Months Update **** I heard a metallic noise under the car and thought it was a torque tube. It turned out to be a silencer. A crack has formed between the intake pipe and the muffler body. The muffler is spot welded in several places, but that's clearly not strong enough. I don't think I've ever had a muffler in the last 1.5 years (only about 5,000 miles)! in sunny California there is almost no rain and absolutely no salt on the roads.
