Plenty of Jeep Wrangler owners use customized a exhaust system to increase performance and make their rig sound better. Jeep Wrangler Exhaust Accessories increase your enjoyment of any mods, plus can boost reliability so you're not stuck in the middle of nowhere. With the DEI exhaust wrap header kit under hood temperatures drop, preventing heat damage. A DEI muffler shield kit also cuts down on heat so undercarriage components don't wear out early.
High flow Jeep Wrangler catalytic converters are one way to free up some horsepower while staying within the law. The way they work is the gaps in the honeycomb structure are larger. Granted, you’d probably need a high flow cat and a regular cat side by side to tell the difference. Don’t expect to notice the power difference in the butt dyno either. High flow converters make the most out of aftermarket exhaust systems over replacing a converter in a stock system.
