Cat Convertor

[BigDirtyJase]

Hi guys,

I've been slowly buying parts to upgrade my car

I've got turbo (HKS GT2535), intercooler (Cooling Pro Stealth Series for R34), front pipe (JJR Bellmouth)

Is a cat from a R33/R34 bolt straight on? I'm looking at a magnaflow 3inch cat that has been flanged already and want to that it will bolt straight on

I'm going to custom the cat back (don't want a cannon tip and can't find what I want around)

the last bit is the suspension - this is proving to be a nightmare...I don't know that the group buy is still going...if it's not going - that what options should I go for (don't want coilovers - too much hassles and I have read the suspension thread and made even more confused )

Yes, 34 and 33 cats use same flange pattern, bolt on.

Have you considered one of these ? Mine came with the flanges, bolted straight on, very happy with it.

I fitted a JJ Bellmouth and Hi Flow X Force Cat. Fitted perfectly on my S1, with a 3" Cat back, as supplied

Increase in power most noticeable and saving about 2l/100 in fuel.

yeah I would love to get a metalcat but there are none around and I have spoken to some exhaust places around my place there is a massive back order for these...they recommended me to go mangaflow (that's my second choice) or to wait (which I can't)

If I can find a metalcat that I can get straight away then i'll buy one

how about the x-force one from jjr, that's flanged too. It says the stagea one is out of stock but they have stock on the R33 ones so that might be alright.

Heard too many horror stories about X-Force cats which has kinda put me off (then again people have them and not report any problems)

Thats the one I got from JJ. Also put in a new O2 sensor at the same time.

I just came op the mountain and the difference with the X Force and bellmouth is amazing.

Before it was like 3 grand plus and 4-5 psi to keep at 60kph, now it comes up at 2and a bit with no boost, so in effect the S1 now comes up in D and not 2nd, hence the better fuel consumption.

Also fitted a hi flow panel filter caus I have a cold air deflector.

I have had a HKS 2535 on an R33 and I tried 3 different exhaust combinations and let me tell you the 2535 is a great punchy turbo but it really needs to breath!!!

If you can gut the cat and you will never look back, it really does make a massive difference.

It also makes your rear bar turn black from the carbon deposits your exhaust puts out too. But who cares when you've got a Stagea that blows flames?

Well I got a magnaflow cat. got it for $280. Now just gotta go to the exhaust place and get the cat-back made up. Xmetal - the reason I didn't get a X-Force 5 of my friends had their one collapse on them after 6 months.

I'm going to go custom as I don't like cannon exhasuts (personal choice) and can't find a aftermarket dual tip exhaust (or maybe I haven't looked hard enough).

I was thinking to go for a de-cat...but i guess i want to go for a sleeper look
