Quite a few people have had the system fitted, I presume its the one with a straight pipe from the manifold back, where it meets up with two small back boxes.
I can tell you that it will be loud/very loud, drone like hell on the motorway, set off car/bike alarms too. However it sounds great on full chat and even around town. Plus the pops and bangs don't sound half bad either imo.
Word of warning however, don't throw away your old system in case you find the toyosport one too loud.
