Are you running power steering? I am and had to beat my new ceramic headman headers to fit. I have heard TTI are the best fit, but I have also heard of some having to beat them with a hammer to fit also.
I figured if there was a chance I would have to use a hammer to make a set of headers fit than I would feel better hammering a "cheaper" ( than TTI's) header.
I won in the end! They fit OK now!
Hey are you gonna paint that car dude? I mean what an ugly colour! And that hood and stripes are just sick!
