Hey,
Im new to the board and have a 88 jdm dohc zc crx.
Problem is after I did my swap my exhaust is really dam loud and exhaust smoke actually gets pushed out of the exhaust pipe really hard. Whne I rev to 4-5k it makes a decent cloud of dirty smoke.
What could my problem be? I think I also may have a small hole in my exhaust just before my muffler, could that be causing all the rukis?

The exhaust is stock so far

It could be a few things, crawl up under there and see what it is. As far as the dirty smoke goes, what do you mean by dirt smoke ? Do you mean its blueish or a dark color ? If so you could be burning oil.
