        Types X-Bomb Cat-Back

        This is a very loud system. Upon installation sounded awesome. However once I drove it on the highway. I quickly realized that there was going to be a problem with drone. At about 2000 rpms there is a very loud drone. Unfortunately this sweet spot is between 70 and 75 mph while in 6th gear. I installed magnaflow mufflers and now everything sounds perfect.

        Ok set

        Ordered it tuesday night got it Friday that's cool. It had a little damage to the ends of the x pipe no big deal 10 mins channel locks fixed that. Went in super easy I have a lift so. It doesnt say it in the instructions but just take the 4 hangers off when you remove the stock setup 13mm makes it way easy went together nice tips were off too close together porta power fixed that sounds awesome.

        My second Pypes product in recent years. I like the level of quality that seems to be improving. Fitment is very straight forward, and leaves a very clean under car appearance. Definite upgrade in sound and performance. My vehicle has not yet been calibrated (tune) and still having gains in MPG and overall performance. Highly recommend.

        Quiet no more

        I love the look and sound of my X-Bomb Cat-Back. Nice and loud. There is a little drone at about 80 under load, but nothing a little volume on the radio can't cover.

      Hi Does it need ECM tuning? H

      • The Pypes X-Bomb Cat-Back Exhaust w/ Polished Tips will not require a tune no.

      In the description for the kit with black tips, it is mentioned that a 3" collector adaptor is included for further upgrades. Is this true with this kit as well? I will install with a "bottle neck elimination" for a true 3" exhaust.

      • Yes, this kit will also include the same adapters that we list for this same exhaust with the black tips.
