    Overall is amazing

    Easy to install. And amazing sounds. The bolts on the clamps could use some improvement as one snapped off when i was tightened with a hand ratchet.

    Worth every penny. 10 stars

    This is an incredible product, excellent sound, quiet cruise, but powerful when you want/need it. Would 100% purchase another one for my Trackhawk coming…once it arrives I will for sure purchase. Unparalleled quality.

    Corsa extreme

    Forsure the best exhuast out there. Took mine around 2 months to get here but 100% worth it and due to covid! But really loud on cold starts and when u want it too be and quiet on freeways! And it has the burbles and pops!! Aways puts a smile on my face! Forsure recommend the corsa extreme.

    Corsa Extreme

    I ordered my Corsa Extreme exhaust for my 2021 Jeep Srt and I’m blow away from the performance and sound. More then exceeded my expectations!
