| i cant say who makes the best, i know of 3 on my regular forum, and thats exhaust depot, dcr and maxxfab. i wont say anythind about the other guys other than dcr imo is over priced. i run the e.d tbe. i knw the owner he's a really cool guy great customer service and if any problems come up he does everything to fix it, so i always recommend him but do your research. as for a code, if you get a cat then no, without cat its hit or miss. most cars dont, but mine does for some reason. it has not adverse effects on the car. usually a spark plug non fowler take care of the code. |
