    Seeing Zoomers and Borla so far as options. Any others thus far? Anyone chime in for performance as well? The stock is wonderful and definitely do not want to get anything aftermarket just for sound lol.

    Thanks in advance!

    We offer a cat back exhaust kit for the Hellcat and SRT as well. Check it out in our vendor section under Solo Performance. They are at presale pricing now as well. Thanks so much!

    IMO, aftermarket cat-back alone offers little if any performance improvement. Especially on the OEM well tuned Helllcat.

    I attended a club dyno in 2006. At that time the only tunes were an initial SuperChips and Hypertech, neither of which offered much if any power increase.
    There were only 5.7L Hemis in attendance. Virtually all dyno'd around 295rwhp with the expection of two that had Dynotech headers and high flow cats (both had aftermarket cat-backs). Those two got about 305rwhp. Many of the Hemis there had Zoomers, Magnaflow, Flowmasters, etc. Some were stock. Little if any improvement found by adding only a cat-back.

    Thank for you the replies! Are there no full exhausts to date yet? By the sounds of it, only cat back for now.

    Gotcha, there should be more options available as 2016 comes. To be honest, stock exhaust setup is pretty gnarly :)

    American racing had a full header back system... Headers should yield about 25-40 whp. Not sure on the entire system. Probably about he same. Stock axel back flows well
