Damn indeed. And plans are the obvious, new fenders, new doors (previous owner got rid of the motors and regulators), new hood, bumper and a clutch replacement for the time being.
Well I just bought myself a 98 Civic EX coupe yesterday. It is a bit rough but I figured why the hell not. Here are some pictures because who doesn't like pictures?
IF you were to go custom Magnaflow, I'd pick one of these http://www.amazon.com/Magnaflow-14832-Polished-Stainless-Muffler/dp/B000CCG082/ref=sr_1_1?ie=UTF8&qid=1364486163&sr=8-1&keywords=magnaflow+muffler
Do you have an aftermarket cold air intake? If so, check to see it's not hitting the connection to the MAF sensor. I've had similar problems, and you have to tuck some wires aside.
