I was wondering if this would be a good buy? He's asking too much and it's been on the market for a while while he was deployed overseas. I'm wondering mainly if it being catless or having an aftermarket clutch is bad for the engine. The engine currently only has 6,000 miles on it supposedly but I can verify that with the dealer.
