Crimp area and dod exhaust valve removal
I removed these sections and replaced them with smooth pipe. I doubt there is any hp gain but maybe there will be later when I am making more power. Took about 3 hours and about $70 in material. It might be a hair louder with the cut outs open but I am not sure. You can just barely hear the 4cylinder mode but it is mostly drowned out by wind and tire noise.
Cat delete, e85, tune are next.
