Hey guys, quick quesiton. This has only happend twice, but I'm just wondering since the car's my daily driver and I just installed a tri-ax. just tiwce this has happend and it's probably because it was the 2 times I wasn't paying attentino when I was shifting, At a dead stop I start and for 2 seconds I get a vibration from the a** end of the car then when I get going faster and get the rpm's a little higher it totally stops(and it's only happend twice). Is it just because I'm letting of the clutch too fast adn not getting the rpm's high enough and the car doesn't like it? ANyhting to check out? Could also be my exhaust tailpipe vebrating against the butt end of my car....lol
