I have a 1997 Mustang GT coupe. Completely stock engine except Flowmaster mufflers. I belive they are 50 series because they aren't much louder than stock but they are really deep. Should I get an O/R X-pipe or O/R H-pipe? What are the pros and cons to each?
get an x pipe much better sound imo. i recommend the dr. gas x pipe over the rest. check out Dr. Gas - X-Overs, Oval Tubing, Performance Exhaust Manufacturer and compare that midpipe to other midpipes out there you will see why the dr gas is a better x pipe.
