    Has anyone heard of these guys? I have seen that they make challenger kits. Wondering what the general consensus on them is.

    SLP was the company that developed the Pontiac Firehawk stuff in the late 80s early 90s. Then moved into other stuff.

    SLP was original housed with Hamburgers Moparts and Hamburgers Oil pans. Moparts was sold off, I believe the oil pan division became Stef's, and I think folded into another company later on. I believe SLP is still in the original location in Toms River, NJ

    i worked for Hamburgers in the 80s and my friend was the one punishing stuff on the engine dyno for SLP in the early days.

    They made a bunch of stuff for Camaro's too, but I haven't heard any reports on a Hellcat product.

    My Cat is plenty loud for me. Aftermarket exhaust is the last mod I would want. IMO the car is perfect.
