The Mac goes on like a condom. I have actually heard the opposite that bbk's are a hit or miss type of deal. They are either going to go on perfect or 3 hrs latter and there on ebay trying to get rid of them
I have heard the opposite also...it goes both ways. I dont think it becomes quality until you step up to Bassani, Magnaflow, Dr. Gas, VRS, etc type of companies. BBK and Mac are both mediocre pieces quality wise but they get the job done for the right price
i went with the JEGS off road h pipe. 100 bucks and i didnt need to pay shipping. biggest waste of money, its crap. it didnt fit right at all, it was like 3 inches short on one side and made my tailpipes look stupid. i ended putting on dumps so it didnt looks retarded out back. go with something quality, you'll thank yourself when you put it on.
