New Member Introduction and First Question - CAT related?!? Meow!

[Tiger_kpt]

Hi guys.

I have been browsing through the forums for a while now and there is some great info, advice and experiences listed throughout it in several areas.

I am new to the forum and this is my first post. I am on the brink of selling my Honda DC5 Integra Type R and replacing it with a GTR33. I have had experience with other turbocharged Jap cars, such as RX7's, etc.... but never Skyline's.

Always wanted a Skyline and looks as though that is going to happen. Taking the plunge!

I was using my RX7 and then my DC5 as my daily driver car... but covering 2000 miles a month in work mileage (commuting only)... is a tad heavy on the old wallet in terms of fuel, maintenance and depreciation of a vehicle. The DC5 has been a great commuter due to good MPG for a sports car... but I know the Skyline would not be so lenient... therefore, in preparation for getting hold of a GTR... I have just bought a Transit Connect Diesel as my work vehicle which leaves the GTR as my weekend toy. I have been quite lucky in the fact that I have been able to insure both the van and a GTR (limited to 3k miles PA) for the same amount that I am paying on the DC5 a year... and the same for road tax.

I just wanted to say hi to you all and introduce myself before posting away on the forum.

Cheers guys,
Kyle.

OK... first question... the GTR33 I am looking at has Nismo down-pipes, a custom de-CAT and an Apexi CAT-back system among a whole host of other parts.

The owner would be supplying me with the OEM CAT for MOT time... but the chance has arisen for me to purchase a very rare Apexi racing CAT.

This was removed from a GTR32... what I want to know is... would this GTR32 CAT section be compatible with a GTR33? Or do the two GTR's have different profile CAT and de-CAT pipes and not cross-compatible with each other?

Thanks in advance!

Welcome to the forum. I`d take the standard cat. I`ve had a raing cat before and it was useless at mot time.

As far as I know both R32 and R33 (de-)cat's are interchangeable

[Tiger_kpt]

Thanks for the reply.

By useless... do you mean that it did not help the car pass emissions testing? Or loss of power was too great?

I was thinking of ditching the custom de-CAT and the OEM CAT section and just having the Apexi CAT fitted permanently to save messing around each year.

Are the R32 and R33 CAT section profiles the same / cross compatible?

As useless i mean it, it failed the emissions beyond all comprehension.

Fair points.

Good to know that the two models of GTR share the same profile of that section - allowing inter-changeability.

hodgie... what brand of racing CAT was your experience with just out of interest?

Sounds as though it could be a total waste of money then.

Not all racing CATS are the same though. You need to look at cells per inch (typically avail as 100/200/300) and get some idea of the overall size.

I'm hoping the dirty great thing Abbey fitted for me is doing it's job
