Hi been looking on ebay for used exhausts and it's slim pickings for our cars....

 

 

However look up mk5 golf same type engine and there's loads and some of the things that are offered for our car are cheaper too.

 

So can another exhaust from the same platform fit our cars?

 

If it's merely exhaust tips aren't long enough then that's an easy fix so long as the backbox mounts up in the same place.

 

I apologies if this has been asked before and if you answer me I'll never ask it again

Mk5 golf back box sits across the back of the car so won't fit.

I bought a "custom" 3" downpipe for a mk5 off eBay that allegedly fitted the standard exhaust but it didn't fit the octavia, I only found out after I cut my mid section and ended up having to buy a milltek cat back to replace the standard one I cut, I think the downpipe will fit the milltek with a bit of work but haven't tried yet. I'd assume from this hat the downpipes are also different.

Before I got the milltek I was looking for a second hand one and struggled like you say, I bought a used blueflame and the guy never sent it so beware of this seller as he reposted it twice and never sent items to other buyers.

It was a black 07 plate tdi, oval tailpipe and the seller was called something like dazzamk3.
