I didn't look as was in work cloths, but I remember that number XSR03 on my exhaust as I took 5 minutes looking up and down the exhaust 3 days ago (under the car) checking for a manufacturer, but couldn't find one. Then today I see the only sticker in my car (came with it) is a metal Magnex stuck on the glove box! lol.
Put boot down a bit on the motorway on way home tonight for 2 miles, sounds ok on fuel revs, but not 'that' loud really. I wonder if it is the cat or points to other problems... hmm.
