Yeah, but for a free oil change, I figure what the heck. I had to go in for the radio/defrost conflict anyway! Also had one of those plastic panel thingies under the car falling off.
I recently had my oil changed at the dealer along with some warranty stuff. I noticed on their invoice that they 'inspected' the exhaust system, but did not change anything nor did they say anything to me.
(I have the $0.58 8 guage wire mod)
I just went from stage 2 to stage 8! (Stage 8 being a single strand of #8 solid copper conducter) The sound is not noticeably different to my ears, but does seem to be a little more mellow, yet still gives that feedback to the driver.
Actually I like the idea of keeping the seal on top. Anyone know where to score some extra muffler gaskets? I guess you could just the piece of wire and forget the gasket altogether.
