1.8-2.0 Exhaust differences

[Baz2004 0]

Is there any main difference between the early 1.8 KR exhaust setup and the late 2.0 16V ?

 

I know the 2.0 has a cat but would the same exhaust fit both cars? What about the G60 8V exhaust would that fit the 16V KR?

The 2.0 is 9A, but not sure if that's any difference though. I'd be suprised if they were different, hangars should be in the same position etc.

1.8 has hooks, 2.0 has hangars, you can modify either exhaust with the right fittings but it needs a bit of welding and the right fittings, I wouldn't think adding the right fittings to the car body would be easy or a particularly good idea.

 

G60 has a cat so the downpipe is different, the 16v also needs the expansion chamber so a de-cat pipe and a G60 downpipe probably wouldn't give the best performance.

So Dave does the 2.0 16V have a CAT? I always thought they had cus I hear of lads gettin a de-cat pipe for them?

yep, any car from 1992 onwards has to have one, all UK 9A corrados have a CAT, for some reason 9A and G60 downpipes have different part numbers, don't know why, I thought even though the 8v G60 has a different manifold, 8v and 16v downpipes are basically interchangeable as long as both cars are pre cat or with cat.

Although a G60 might run OK with a decat pipe I'm sure the 16v's are affected by not having a CAT or front box on the downpipe so the hot gases can expand, although top end the 2L 16v probablt benefits from not having a restrictive CAT, low end may be a different story.

Perhaps it's becasue of the forced induction that G60's aren't affected???
