Build Your Next Exhaust System with Oval Tubing for Better Fit and Ground Clearance

As you power up your project the exhaust system needs are certainly a concern. You probably have manifolds or headers already picked out for fitment reasons like an LS swap, but south of the manifold or header exit is often left up a local exhaust shop and their limited product line. If your build needs the capacity of a 3-inch exhaust system, then you’re further compounding the issue trying to fit a pair of 3-inch “sewer pipes” under your car. Then, even if you do find the room for 3-inch dual exhaust (which often just ends in dumps at the rear axle) it is now usually the lowest part on your ride and will kiss every speed bump it meets. What to do?

The answer is in the same type of exhaust NASCAR has been using since the mid-’90s, oval exhaust tubing! The oval exhaust tubing cross section provides for increased flow while not requiring any more height than most standard exhaust systems. We offer 3-inch oval exhaust pipe for your performance exhaust needs with a cross section of 3-1/2 inches by 2-1/4 inches. That means you have the horsepower support of a 3-inch exhaust, but it only needs the typical 2-1/4-inch pipe clearance height wise, perfect for lowered vehicles or vehicles with minimal traditional exhaust routing space.

Oval Inlet and Outlet Stainless Steel Mufflers Work Seamlessly with Our Oval Tubing

Building a custom 3-inch oval exhaust pipe system means at some point you’ll need to decide on a performance muffler. Instead of trying to adapt a performance round muffler with a round inlet/outlet from round to oval exhaust pipe, we have designed and built a great sounding stainless steel performance muffler that uses oval inlets/outlets to work directly with our oval tubing. Crafted from T-304 stainless steel for a long service life, the internal design of our oval muffler features a perforated through tube with fiberglass and stainless steel packing material for that deep muscle car sound we all love. Built with a standard center inlet and offset outlet, the inlet and outlet are reversible to provide for the best fit in your vehicle’s chassis.

Our 409 stainless 4-bolt flanges are an option if you prefer bolt-together exhaust sections going into and out of your oval muffler. They are 3/8-inch thick for a leak free seal that won’t warp and can be directly welded to the muffler inlet and/or outlet. We further support your oval exhaust pipe system build needs with full oval exhaust builder kits to get the job done easily.
