Yes I have a Toyosport system on my Plus, but needed to fit a sleeve around the cat outlet pipe for the centre pipe inlet to fit around, using a band clamp too. A good price and well made, but you may need to faff around a bit for a proper fit, not sure why they don't make the centre inlet pipe the correct smaller diameter to match the OE cat outlet?
I fitted mine yesterday, and had to sleeve the outlet from the cat. The rear muffler outlet doesn't sit quite right in the bumper cutout, and no amount of playing around got it to where I was happy. I'll take it to work next week and bend the stainless rods used for the rear mount to get it to sit a bit better. It took me quite a while to fit, and besides the outlet position I'm very happy with it. Considering I could see straight through the rear muffler and the centre muffler is deleted I was concerned it would be too loud, and was surprised that it isn't. A low rumble at idle and lovely sound through the revs. Cruising it's unobtrusive and with the windows up the road noise from the tyres is louder. My seat of the pants dyno says it pulls harder as well.
