That's probably why the 3.6 box fitted my 3.4 tip, but the 3.4 one you had didn't fit your 3.6.

Edit: I couldn't say if the 03 tips will fit the rear bumper openings, but you could use your original tips on the new boxes.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Quick exhaust question: Apart from having different tips (or so I believe) is there any operational difference between a set of C2 back boxes from a 2003 car and a pre-facelift 2000 car? I am looking to be able to fit the later boxes onto an earlier car - I assume that the tips will fit the rear bumper gaps OK too? Thanks in advance Guy

POST 2Original post

The silencers are slightly different internally between pre and post facelift, but the external fittings are the same. You shouldn't have any problem. Edit: I couldn't say if the 03 tips will fit the rear bumper openings, but you could use your original tips on the new boxes.

POST 3Original post

I had pre-facelift backboxes fitted to my post-facelift car (twice!) and the mounting brackets are located in slightly different places. Nothing a welder couldn't manage in a few minutes.

POST 4Original post

That's odd. I have 'facelift' boxes on my car, and they fitted fine - no mods at all.

POST 5 / ORIGINAL POSTEROriginal post

Thanks Richard / Rodney, you're a mine of useful information as ever. I'm looking to get the Oettle style modification done but I want to be able to swap back to standard should I need to. I've found a set of back-boxes but they are from an 03 car hence the question. I am going to get the 03 ones modified and fitted and keep the current back boxes standard in case I need them.

POST 6Original post

I think the difference may be between tiptronic backboxes and manual ones. Richard, do they have different part numbers?

POST 7Original post

If you haven't already, it's worth considering Hayward and Scott to do the modification as well. Would work out slightly cheaper as well from the Oettle conversion / sending the boxes over to Germany.

POST 8Original post

I think you are correct, but, strangely enough, there are different numbers for manual and tiptronic on 3.4 cars, but only one number for standard 3.6s. That's probably why the 3.6 box fitted my 3.4 tip, but the 3.4 one you had didn't fit your 3.6. Confusing...... (There is a different number for the C4S, btw.)
