Bit of an Exhaust pickle

But with a aftermarket one like that, it's designed to work with the engine and get some power from it.

It really is a hit or miss when it comes to custom exhausts, unless you speak to a company called Simpsons Exhaust and they will design a exhaust to the spec of the engine..... build exhausts for racing car, etc..... but a cat back system they ask £700! :censored:



you get what you pay for then eh?:drool:

Q. What is a resonator and what's the difference between a resonated and non-resonated exhaust system?
A. A resonator is a chamber in the exhaust system that contains a specific volume of air which is designed to cancel out certain frequencies of sound (made by the engine) - making the exhaust noise quieter.

Therefore, a non-resonated exhaust system will give you extra performance and a louder exhaust note and the resonated system will give you extra performance without increasing the exhaust noise much.

so dave you reckon a mk3 cupra exhaust will be up to the job?

Because of your boost powered engine then a aftermarket (n/a) 16v exhaust wont be any good! From talking to custom exhaust companies in the past usually go by 2.25" for an N/A engine and 2.5" for a boost, depending on turbo / supercharge you could get 3".

I know the mk3 boys that run a KO3s or bigger use a 3" downpipe.

So simple answer, although it's not totally designed for your engine a aftermarket Mk3 system would be better suited for you compared to an aftermarket 16v system. Or go and see a custom exhaust company and while you at getting a new system, get rid of your cat ;)

But with getting a decat you may have the problem that some of the 16v boys get is that the downpipe and cat are one complete system. :whistle:

...think i meant this one, surely if it's "for a diesel" it doesnt matter?...
AFAIK, mk2's and mk3's share the same chassis and floorpan, but the mk4 is rather different underneath. Not sure if it being for a diesel has much of a bearing on that TBH. In answer to your query of "does it matter", I guess the answer is something along the lines of "not if you don't mind it being the wrong shape and having bends in all the wrong places". :whistle:

Cupra mk3 exhaust will fit a treat as a stopgap but 3 problems

1- The rear box hangers (easy bolt swap to mk3 if wrong axis on original)

2- Bore size (mk2 16v/mk3 20vt same bore 55.5mm) whereas as your 1.8 is 50mm iirc so will need a adapter to fit

3- Condition as most original ones are tinworm food now
