Break your Jeep through the bottleneck.

Our catalytic converters move air fast. A high-flow catalytic converter gets your exhaust moving with quickness, and that gives your Jeep more horsepower and low-end torque. And, when it comes to moving through muddy slop, there's nothing more important than low-end torque. Well, a good pair of tires helps too. We've got custom-fit catalytic converters for all the MVPs of the Jeep off-road world like the Jeep CJ, Jeep CJ5, Jeep CJ7 or Jeep Wrangler.

If you don't have a dirt-loving devil, and you're looking to replace your catalytic converter, we have a great selection of replacements too — and every one meets or exceeds manufacturer's requirements.

Get bent...into shape.

Getting your Jeep exhaust pipes from the manifold to the muffler is no easy task. Especially if you've made some modifications or want a custom exhaust. We'll help you get from point A to point B, even if it takes some bends, twists and splits for a dual exhaust. JC Whitney carries the full spectrum of exhaust pipes and tubing. We have replacement exhaust pipes, pre-bent exhaust pipes, flexible exhaust tubing and even pipes you can bend yourself — for the true exhaust-system sculptor. No matter what route you go, you'll be able to choose from stainless, aluminum and chrome pipes. With a greater airflow you'll be churning up the dirt like it's nobody's business. Your options really are infinite, so the only question is, "How will you combine them?" With a gasket, obviously.

Get the most out of your block.

Your Jeep will be screaming on road and off in no time. Boost your Jeep's horsepower without boring your engine by unrestricting airflow with high-performance headers and exhaust manifolds. JC Whitney has thousands of custom-fit Jeep headers and exhaust manifolds for all the hot machines like the Jeep CJ, Jeep CJ5, Jeep CJ7 or Jeep Wrangler. And, we carry the manufacturers, like Omix Ada and Pacesetter, who've spent years building trust by consistently cranking out high performance parts.

Gaskets anybody?

Find everything you need to fix, install or upgrade your exhaust system. From full installation kits to nuts, brackets and gaskets, get the parts you need to get the job done. And get it done right. (No, we don't carry coat hangers.)

From silent to booming — and everything in-between.

Mufflers are all about sound. Well, they can add a few horsepower, but what you really want is for the world to know you've got a mean off-roading machine (especially the hungry bear at the campsite). And what better way to announce your Jeep to the world than with the low rumbling of a muffler? A rumble that just hints at all the power you have at your control. For a crazy powerful sound, look into our Flowmaster muffler.

If you're not a gear head and just need to replace a muffler that's been up close and personal with the pavement, we've got all types of replacement mufflers too.

The one-stop shop.

This is the spot to get your complete exhaust system, from the header pipe to the exhaust tip. We've got all types of systems for all types of Jeeps: CJ, CJ5, CJ7 or Wrangler.
