    So far, GREAT Replacement!!!
    Well, I’ve only used it for less than two weeks, but I’ll dare to say it’s great. I had it installed by a professional, so I can’t say how difficult the install is. But it’s better to opt for professional installation. This converter is very durable and well-constructed. But most of all, it performs great. It helped restore lost power and improved fuel economy. Amazing buy!

    AP Exhaust
    My GMC was performing badly going up the hills and mechanic coded it and all the mistakes were related to O2 sensors, I needed a really good converter which could fix all these issues and with long time service warranty, a friend of mine recommended me TRUCKiD and so will do I - also recommend it. Mechanic put it on, and it was the best day of my GMC life.

    Back on the Road Again
    My Wrangler was throwing codes like crazy but this converter fixed it right up. Direct fit, no hassles, the engine feels much much better already. I had no problems at all with the smog check. TRUCKiD shipped fast.

    It Does the Job
    I'm not super handy but I managed to get this installed without calling a mechanic. The engine light is gone and my truck doesn't sound like it's dying anymore. Definitely worth it.

    So Far So Good
    This converter solved my issue and was indeed direct fit. Exhaust is being catalyzed again and smells much better and the CIL has remained off for over 1k miles so far. Price and quality are top notch combined with super fast shipping is why I choose TRUCKiD first. Thank you very much!
