Hi, All I want to get a decat for my new Jetex system but don't know which one will go straight on?
Any help would be great ;)
-
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 would assume mine is also 2.75"
-
where did you get 2.75" from mate?
-
Forums. But looking at the jetex website mine should be 2.5"

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.

Mine a 2.75" it there top end system. And matched with 3" custom decat
-
You fitted it yet?
-
Yea the cat back system is on and fits fine, but mine is the kit that sit below the standard valance rather than the 4mo style. Still waiting on getting decat.
-
is your car lowered? im asking as my rear box on my jetex sits so close to the rear springs is stupid. rang jetex said it a know issue on the lowering th emk4 on there systems which i though was stupid as the dub scene is lowered cars!!! :angry:
-
yes but only a little, My back box sits low though because its under the valance ,where as yours should sit higher than mine.
Off subject, have you posted the S2000 filter?

yus mate sent you email did you not get it?
sent recorded etc
on back box intresting as i cut my valance out and still not perfect
-
sent email again mate
-
I bought the kit that sat below the valance because I didn't want to spend another £50 on a valance. But I have also read issues with 4motion style exhausts not fitting very well, and people cutting away part of the chassis a little bit to stop the back boxes knocking/rubbing.
-
Exactly what we did. But like say still a iffy fit if honest
