    89027 - Thrush Header Back Exhaust Systems is rated 2.8 out of 5 by 6.
    Rated 5 out of 5 by from Fit well, even with leaf springs I bought this for my son's 68 GMC longbed, with leaf springs. The instructions said it would only fit coil springs, but we tried it anyhow. Without any modifications it fit!

    Rated 5 out of 5 by from Nice!!!! Exhaust system comes poorly packaged and FedEX denied delivery twice. Had poor customer service the second time I called JEGS about the issue. Exhaust system fits great on 71 C10 long bed with Headers. Best price I was able to find for a bolt on exhaust system header back. Sound is somewhat quiet at idle but opens up when at full throttle. I can still have a conversation in cabin at cruising speed with no annoying drone.

    Rated 3 out of 5 by from Good Quality, Poor Packaging! I purchased this system and when I recieved it, the box was ripped and destroyed, all the accessories that were or should have been in a bag or box separately within the main box, was non-existent! Nuts and bolts where everywhere, clamps were just scattered about and to the point of me almost returning the whole dam thing! It took me 4 hours to match up all parts and pieces regarding nuts, bolts, clamps and hangers. There were no instructions as described, either! The quality of the system was perfect though!

    Rated 2 out of 5 by from Missing many pieces I bought this online, shipped to me at home. Those two steps were awesome. Delivered to my mechanic and he informed me that many little parts were missing and one of the two mufflers were missing. Very disappointed!

    Rated 1 out of 5 by from Trailing arm application only!! I bought this for my '70 Chevy Longhorn along with other items. After opening the box and looking at the enclosed paperwork it stated that it would only work on a trailing arm truck and it was not for a leaf spring truck. I'll keep it and alter it to fit instead of costing me more time and money that they should of put it in their listing instead of letting the customer find out after the purchase. The kit is top quality and I would recommend it for someone who has the truck with trailing arms.

    Rated 1 out of 5 by from Suck Terrible fit I’d been better off buying a universal kit an building it from scratch because that’s what I had to do with this kit.
