Increase Low-End Torque and Throttle Response by Adding an Exhaust Crossover

Dual exhaust applications can see a nice bump in low-end torque and better throttle responsiveness when a crossover pipe, or “H-pipe” is installed. This is because the crossover pipe provides equalization to the exhaust pressure pulses coming from the manifolds or headers. This exhaust pulse scavenging is what helps with the throttle response and torque at the bottom of the tach. Furthermore, adding an H-style crossover will often help with exhaust system drone by canceling certain exhaust note frequencies. H-pipes are also known to create a slightly deeper exhaust note overall versus the popular X-pipe crossover, which is typically used when peak horsepower is a priority. The typical exhaust H-pipe installation will often net a 5-15 horsepower increase depending on where the exhaust crossover pipe is positioned.

Crafted from .0625-inch wall mild steel, our universal H-pipe crossover kit features pre-welded T-connectors to fit into your left and right exhaust system mid-pipe area after your header or exhaust manifold. These T-connectors include expanded openings to allow them to easily fit over your existing exhaust pipes for a weld-free installation using the included exhaust clamps. The crossover portion can be completed by using either the included 24-inch long straight section or 23.77-inch long 16-degree center bend section of exhaust tubing. The 16-degree center bend tubing helps clear the transmission or driveshaft on vehicles where the exhaust system is tucked up close to the drivetrain. The straight section makes for a simple straight across H-pipe exhaust connection on vehicles where there is clearance. Just like the T-connectors, the exhaust crossover pipe is designed to fit into the expanded opening of the T-connector and secured with the included clamps.

Overall Assessment

Customers highly value the product for its high quality, versatility, and affordability. It is a well-designed H pipe kit that fits well into various applications and enhances performance. The kit was hailed for its practicality, with the straight and angled cut-to-fit crossover pipes offering flexibility for different projects. The product is easy to install, and some customers appreciated the inclusion of clamps for those without access to a welder. A few users mentioned that the part improved the sound of their engines and even quietened them. Despite being used in various models, from trucks to Fairlanes and Mustangs, the H pipe kit was found to work remarkably well. While some mentioned its tendency to rust, overall, customers recommended the product for its multifunctionality, price-value ratio, and overall performance.

Quality H pipe kit

I purchased this H pipe kit for the dual exhaust I am fabricating for my 63 Fairlane. These cars are not well supported in aftermarket as they are a little different from Falcons and Mustangs which have wider selection of vehicle specific parts. One company makes a complete kit that is too pricey for my project so I bought pipes for an early Hipo Mustang since I am using the hipo exhaust manifolds. The H pipe welded into the front pipes is too narrow for the Fairlane so I cut it out and am fitting up the pipes with the parts in this kit. The straight and angled cut to fit crossover pipes give me the needed flexibility for this project.
