Product Reviews

Just got these on to replace my roush axle backs. I also have cat and resonator deletes and this is exactly what i was looking for. perfect tone, nice and deep, but still loud WOT. as for the finish i cant say anything but gorgeous. Defiantly would recommend and will buy again for future cars.

Steeda you never disappoint, always top quality products. I have been a long time customer, and owned four different Mustangs over the last 15 years. Ever car that I purchased Steeda parts for has been greatly improved. Keep up the good work and thanks for you commitment to produce the best.

Guys, the sound of this exhaust is excellent but let's put all that aside for a moment. It saves you 22 pounds from your OEM exhaust!! This setup is worth it for that reason alone!

Awesome steeda

Steeda does it again - this exhaust sounds amazing and makes the car sound like a true beast!

Did a lot of YouTube research and this is def one of the better sounding exhausts on the market. Fast/free shipping also helps!

Love my Steeda axleback exhaust for the GT! Now it finally sounds as it should and people can hear me coming from a block away - no drone either!

If you go with this exhaust setup you definitely won't be disappointed. They sound great on the highway (no drone) and get really loud at WOT (wide open throttle).

Install went super easy and gave me the sound i was looking for. Not obnoxious like them fart cans found on hondas... also like the fact that they reduce weight! Great job Steeda

Super fast shipment and very secure payment. Install says typically hour and a half, did it in an hour myself.sounds aggressive, thanks Steeda!
