1995 Jeep Wrangler started to develop an annoying rattle from the exhaust whenever the engine was running. Crawling underneath to do a little shaking and beating indicated that something was rattling around inside the original, 17-year-old muffler. Time for a replacement. I wanted to get a full stainless steel replacement cat-back system, but it just wasn't in the budget. I opted instead for Pacesetter TFX Kat-Back system made of aluminized steel. It probably won't last as long as a stainless system would, but it cost only 1/3 as much.
