I recently bought a Walker muffler with attached pipe which is a perfect match for my PT Cruiser. While the replacement muffler looks exactly like the factory muffler, it is a "quiet flow" style that offers improved flow. What didn't impress me were the compressed elbows that caused flow losses and looked ugly compared to the muffler. My goal was to add a little flow while keeping quiet decibels on my cruiser. I ended up cutting off the Walker exhaust pipe, leaving just enough material to flare
