    Speedway was amazing, great customer service and fast shipping. As for this exhaust system the pipes itself fit right the the collector flange wouldn't fit over the expanded collector pipe and needed to be ground out to fit and also the collector end on the pipe had to much pipe flared out and wouldn't allow the collector bolts to pass through. One last thing with the supplied bolts and brackets as 2 lag bolts that is supposed to be used in the crossmember are for would not metal and I had to get replacement bolts.
