Product Overview

Steeda's GT350 H-pipe is the perfect way to bring a unique and more classic muscle car tone to your 5.2L flat-plane crank engine. You can expect a deeper rumble at idle and a growling acceleration when you upgrade to this resonator delete.

More low-end power. H-pipes are known for delivering more low-end power and torque, while x-pipes deliver high-rpm per formance. This upgrade is a great way to give your Shelby's low-end power a nudge.

Unique sound. If you are looking to make your GT350 stand out with a one-of-a-kind sound, this is the way to do it. The H-pipe delivers a growling and tough sound while both the stock and aftermarket x-pipes have a nasally and raspy note.

A lifetime of per formance. Incorporating manufacturing and design elements borrowed from our popular GT line of X-pipes and H-pipes ensures this great-looking piece lasts the life of your Shelby. Manufactured from T304 stainless steel, this H-pipe will stay looking great for years and will not rust or corrode. Heat may discolor this 304 stainless system, but you have no worries about the exhaust rusting through over time. This is much improved over lesser T409 or aluminized steel exhausts that can develop rust or even develop holes over time.

Reduced restriction. Eliminating the resonators, this H-pipe improves the flow of exhaust gasses from the Voodoo engine while also reducing weight and slightly increasing volume. The H-pipe will replace part of the exhaust behind your catalytic converters and in front of the axle-back.

No-weld installation. Steeda's H-pipe can be installed easily and requires no welding. The resonator delete clamps into place with a pair of flush fit exhaust clamps for a clean and simple install. To remove the factory resonator, the heatshield will need to be removed and the exhaust will need to be cut. Exhaust clamps included with the H-pipe allow you to easily re-install the factory resonator if you ever want to return your GT350 to the stock system.
