When it comes to performance exhaust systems, most people are looking for three things: Power, sound, and quality. JBA Exhaust Systems deliver the best of all three, giving it both great looks and performance. One of the first performance upgrades typically made to a vehicle is the addition of a performance exhaust system. While there is a high demand for performance sound, the capacity for power in a JBA exhaust system gives JBA the extra edge. Each system is tuned to provide the best possible exhaust tone without being overwhelming from within the vehicle. By replacing the restrictive factory exhaust system with free flowing mandrel-bent stainless tubing and quality performance mufflers, JBA has developed the power, sound, and efficiency desired in a vehicle. Each kit is finished with a polished chrome plated stainless steel tip that resists discoloring, along with high quality hardware and thorough instructions for a simple bolt-on installation.

This JBA Axle-back Exhaust features a deep burble on idle and gives the Mustang a strong traditional V8 Sound on lower RPM bands. On high RPM bands, this exhaust turns from deep burble to a mid-range note for an all-rounded sound.

JBA axle back exhaust

By: on 12 October 2019
Did a lot of research to find the ‘right’ axle-back exhaust for my 2017 Mustang and the JBA 3 inch kept coming up in the reviews as the correct match for my needs - deep exhaust note, slightly ‘old school’ rumble, not raspy or excessive and no in-cabin droning. Purchased my set from Mustang Motorsport recently and very pleased to say that the exhaust performs exactly as described in the all of the reviews that are out there - wonderfully deep note at idle, very slight cackle on over-run, a note that turns heads but is not excessive, no in-cabin drone and the throttle response feels more crisp. Happy to add that the ordering process (through Mustang Motorsport) was easy, great communication and delivery from Melbourne to Sydney was at a very reasonable cost and completed in two-days! Very happy to recommend this product and supplier.

looked at lots of online videos but didn't like the raspy harsh sound a lot of axle back and cat backs have. The JBA has a really deep note, have only had it installed for a few days and already had people saying how good it sounds. It took about 1 1/2 hours just taking our time to set it up properly on the hoist making sure everything was 100% I also disconnected the engine bay sound tube which I'd recommend if installing any aftermarket exhaust Overall a good value system, sounds great and not too loud.
