Q: I bought the drager exhaust for my supra three years ago and noticed only a day ago that the exhaust piping was starting to rust through. Are these mufflers covered under your four year warranty? I dont think that I have the receipt but I would have to look around for it. Any help with this question would be appreciated. Thanks!

A: Only the full stainless versions are covered under the 4 year warranty. The Drager, which is stainless muffler with aluminized piping) is covered under the 1 year warranty. We havent seen many of the non-full stainless systems have issues, unless there was scrapping or impacts onto the piping. Regardless, If you like, you may still contact the dealer it was purchased through to have it address. From there, the dealer will contact thier rep here at HKS USA and see if there is something we may do to assist you in this situation.
