Wouldn't of thought so, what make is it? Or is it a custom.
Well if you have a look at the exhaust does it say anything? Or even better take a photo of it and upload it
i have the exact same exhaust and i was told it was stainless steel when i bought my car too but it is not (my fault for not checking). to me it doesn't sound amazing but it's ok, it has a bit of a deep muffled tone, mine doesn't sound tinny or high pitched. perhaps it could have something to do with the cat joint?
i have a k-tec cat back system on its way over to me so that will be replacing it
