The Flowtech 53620FLT X-Terminator X-Pipe is a universal 2.5-inch cross pipe built for dual exhaust systems on muscle cars, trucks, and street-strip builds. It ties both exhaust banks together with a crossover, which balances pulses between sides and improves scavenging through the rest of the system. The mandrel-bent tubing keeps the inside diameter consistent through every bend, so flow stays smooth where a crush-bent pipe would choke it down. Builders running a true dual setup who want better velocity and reduced backpressure without fabricating a custom crossover will find this a straightforward bolt-in section for the midsection of an exhaust system.
Construction is aluminized steel, with overall dimensions of 23 by 56 inches and a 2.5-inch inlet and outlet diameter. The mandrel-bent tubing is the key detail here: by holding the full 2.5-inch bore through the bends, it cuts the restriction that turns down exhaust velocity in pressed pipe. Flowtech includes the collectors, gaskets, and U-bolts needed to splice it into an existing dual layout, so you are not chasing down separate clamps and flanges to finish the install. The universal sizing means it pairs with common 2.5-inch tubing, and it works alongside a matched muffler pair or a fresh set of headers when you are reworking the full system.
This cross pipe suits anyone converting from a single exhaust to true duals, or rebuilding a tired midsection on a V8 street car or pickup. Position it after the headers or manifolds and ahead of the mufflers, where the crossover does the most for pulse balancing and exhaust note. Because it ships with collectors, gaskets, and U-bolts, it slots into a 2.5-inch system with minimal extra parts. If you are still sizing the rest of the build, compare it against an H-pipe layout or browse our wider exhaust catalog for clamps, hangers, and tubing to complete the job.
The kit ships with the mandrel-bent cross pipe along with collectors, gaskets, and U-bolts. That covers the parts needed to splice it into an existing 2.5-inch dual exhaust system without sourcing separate clamps or flanges.
It has a 2.5-inch inlet and outlet diameter, so it mates with common 2.5-inch exhaust tubing. Overall dimensions are 23 by 56 inches, which gives you room to position the crossover correctly between the headers and mufflers.
Yes. The crossover ties both banks together, which balances exhaust pulses across sides. Combined with the mandrel-bent design that keeps the full bore through every bend, it reduces backpressure and increases velocity for better scavenging compared to a pair of unconnected straight pipes.
Per manufacturer specifications, it is built from aluminized steel. The mandrel-bent tubing holds a consistent 2.5-inch inside diameter through the bends, which preserves flow where crush-bent pipe would restrict it.
Mount it in the midsection, after the headers or manifolds and ahead of the mufflers. That placement lets the crossover do the most for pulse balancing and tuning the exhaust note before flow reaches the rear of the system.
