what diameter is your jetex exhaust?
just buy one of the ebay ones and if it doesn't fit, get an adapter.

i too own a jetex system (i wonder if you too will have poor fitting issues??????? ) the decat as above you could get a ebay one and adaptor it together. i went custom with a proper flange welded to the jetex cat back and then a 3'' down pipe with flange with a drop in and drop out sports cat cost about £200 all in and fit and works a treat.

I'd be very suprised it if it 2.75", most will be 2.5" with a reducer to bring it down to 2.25" where it joins the cat.

I chopped the 2.25" bit off my decat and had a bit of 2.5" welded on to meet my blueflame system  :smiley:

My jetex system is 2.5" and mates directly to the stock CAT, and was a perfect fit according to the fitter. So my question is what size is the stock cat so I know what decat my Jetex system will mate on too.

Cat is 2.25", your jetex will be 2.5" until the end where it was reduce to 2.25" to join with the cat, same as the Milltek systems.
