I feel like there is probably already a thread on this but I couldnt find it. I'm thinking about ordering the modified Flowmaster super 40 from west coast fieros. Has anybody tried this part? Or has anybody got info about WCF iv heard they are very slow to process but do good work. Also this muffler is a direct fit im assuming? It dosnt really say, it just says "modified to fit" will I need new tips? Or any adapters? Any help will be greatly appreciated. Thank you in advamce
