Exhaust System Bores

[stuart1298 6]

can any one tell me the diameter of a 205 exhaust system, the reason i ask, mine got put out side the garage, and the scrap man has picked it up, i've got mu down pipe for my turbo from 2.5" diameter, and need to make the rest of the system up

Have a quick search, it's got to have been covered about a bazillion times. I'm 95% it's 2" for a 1.9 system but can't tell you for sure.

 

If you're making a custom system I'd make it 2.5" to match your downpipe, turbos like low back pressure.

1"7/8's I think for earlier systems, the 2", got a 2.25" custom system on my 1.9 from the standard downpipe back
