Hi all just had HKS sports cats mated up to my Fujitsbo titanium system on the zed. Still sounds nice and stealth until you turn the loud pedal up Very nice sound indeed. Got kwik fit to do it and give it another oil change. £39.99 for 5w 30 synthetic mobil super s inc filter, and 60 bucks for fitting the cats which was well worth it, took 2 of them a solid hour and it`s an awkward job, couldn`t of been done without ramps. If i had one of them i`d be under the car all the time cleaning and polishing. Almost ready for brands hatch on the 10th, just need brake pads all around and drop links for the rear ....and more money would be nice
