480 Turbo Exhaust

Post by yorkievolvo » Tue Nov 08, 2022 2:00 pm

Has anybody, in the last couple of years, bought an exhaust system for a 480 Turbo?
A corroded exhaust rendered my car an MOT failure.
As I’ve not managed to locate a Turbo exhaust system, in desperation, I’ve obtained a bog-standard system but now I have questions.
What will happen to the performance/behaviour of my car should the b-s system be installed?
Or, can the b-s system, actually, be installed or would it be too detrimental to performance?
For anybody who's interested in looking it up, the part needed is: Green Parts-book, group 25, page 126, item 26 (my b-s bit is item 10).
I'm considering cutting the new item (10) and, using a reduction joint repair kit, joining the back part to the forward part on my car (item 25).
Or, and here's another question, would it be better to remove both items 26 and 25 and connect item 10 to the car's item 6 (Cat).
Any, and all, information gratefully received.

Ordered - thanks Jeff, don'tknow how I missed that one.
Just one niggle. The company say it's suitable for an 88KW engine but not suitable for a 90KW engine.
How do I check/confirm which engine is installed in my car?
Any takers?

88kw (B18FT) and 90kw (B18FTM) is the difference between a factory power-sapping cat and the non-cat. Obviously, that has a significant difference in what exhaust is fitted.

Only in the very early days was a UK Turbo non-cat and even then it was a no-cost option (I think).

The FTM was more popular in markets with less stringent emission regulations.

Breaking down the VIN will get your engine code here

The engine code is also on a metal plate on the block, forward facing, adjacent to the TDC tool hole and oil filter.

Or, just look under the car.... if it's cat equipped, it's the lower powered 88kw "FT".

Thanks for the info - very interesting.
Now, can I ask another question - can I remove the Cat. & bin it?

The emissions requirements of the UK MoT test will mean a catalytic convertor will need to be fitted for vehicles first used 1st August 1992.

Before that date, you can remove the cat and pass at the 3.5% CO level.

There is a grace period 1992-1995 for vehicles listed in the annex that didn't have a cat from new - but no 480 exists in here. There are just some oddball Rovers and smaller manufacturers like TVR that exist in this grace period.

If you do decide to fit a decat pipe, its extra awkward because the mouth of the cat houses the O2 sensor. If you are swapping the de-cat pipe every year for the test, you have to swap the o2 sensor too, or move it upstream with a new O2 boss.

Jay-Kay-Em - thanks for the info.
If fine tomorrow will have a go at the car.
The cat will not be removed - just hope it's still working.
