Default Will different exhaust mess up my tune???
Ok so i am ditching the true duals for a single exhaust. I am gonna run 3" off the collectors into a 4" merge collector with a 4" e-cutout, after the cutout i am gonna merge it back down to 3" and maybe put a cat and a really quiet muffler from a muffler shop or something. What my question is will i screw my tune up driving it around daily with the cut out closed and when i want to race open it up???? Thanks for info in advance.
