Yes, LPP and a few others (all the same company using different names) have knocked off my exhaust design, and somehow made copies of our rejects. They have made a copy that's pretty close, but definitely up to our design standards. We've had run-ins with these people before regarding them copying our exhaust products that we have put many hours and thousands of dollars into creating. They've copied our Corvette sidepipes, our 2010 Camaro sytems, and a specialty Mustang header that will only fit one particular head style, none of which they even know about or have listed as such. They sell the stuff for less than we can even buy our products for, which leads us to think they are having them made overseas. Not that that is a problem per say, but it's not the same as ours.
We've gotten several calls regarding problems with them, and they aren't offering complete kits. The hardware for them isn't available from anyone but us, so there is no clamps, mounts or fastners, as well as the tunnel block off plate that goes with it.
I can't vouch for their fitment, but knowing which prototype sets we've rejected, they won't fit very well, and off the shelf clamps won't fit without modification.
You get what you pay for, and we can't stand behind any of the knock-offs.
We've actually tabled our production of our kits until this copy-cat matter is settled, which we believe will happen once they have sold out of them. We've considered buying all of them just to clear the market of the junk, but we can't find out how many of them they made. We believe there were only 30+ sets we know of that they are trying to sell, but we can't find physical addresses, names, or anything for who they are. Just remember, sled stuff from Florida or North Carolina is not likely to be made by someone who understands sleds, especially someone you can't contact ro find any trace of! We have no distributors, vendors, or other sales locations, so if it isn't purchased from us, it isn't the real thing. As of now we aren't selling them simply due to this mess, but will return when the time is right.
