Downpipe compatability (TSI)

[zei20t]

Can i ask which site you got it from?

ebay! it was a german seller called turbooj.

I got a mk5 down pipe that is being modded by a mate.

IMO, get a mk6 one and have it shortened to fit the octavia

Ok so I'm pretty certain on this downpipe.

I was asking in another thread about all these bolt on options, of which most are 'decat'. From reading above people saying it will be for track only...

My question is, as 95% of these on eBay are decat, is running one of these to an otherwise stock exhaust illegal in Victoria?

If so, what is the work around? Buy one only if it has a low-cell, hi-flow cat? Just not really sure about this point which osy main hold up on buying one. I assume there's so many for sale all the same its got to be right

One more thing, does this one look right for my car? They all have the same turbo mount and exit diameter, and 2 o2 sensors, and the double mount hooks.. just length is the issue.

Cheers for the mass questions!

OK, picked this up from the post office this morning, great quality. yes has the TFSI flange on it which ill have 2 holes elongated to fit the TSI.

Being decat? What is the cross threaded section after the turbo mount?

decat pipes are highly illegal, and of course mine is only for use on the track

anyway, that's flex pipe to allow for engine movement.

mine went on this weekend gone, so much better to drive

Where should I look for a catted one lol. Money ^^^ now

I swear someone told me earlier on here that since it only takes out one of two cats its fine?

[MountainBikeMike]

Should I still get the above then get this welding in between since for the Octavia it needs to be shortened anyway?

Would end up about $350 for the parts that way...

from what darkshadow has experienced, get one for a jetta, looks like its the right fit.

if you get a decat one, buy that cat too.

indeed it is - from engine outlet to tail pipes
a mk5 jetta that is.

Awesome, thats helpful. Well confident now.

Going to an Muffler Man Prahran tomorrow to see if one he has there fits. Its a Polo one that someone bought from the states and it didn't fit... If it doesnt fit mine, I'll get this, it says Jetta MKV!:

BUT its: Pipe Size: 3.0" / Pipe Outlet Size 2.5". SO I'm imagining I'd have to go for a 3" cat? Zei20t and dArK5HaD0w, are your downpipes 2.5"?

I've got a quote of about $80-120 for them to weld in the cat, and me install the rest first. Is that steep?

My final question would be on which cat to go for. Is there a 100 or 200 cell requirement? Are brand names going to make a difference?

Theres a $100 worse name brand 2.5" 100cell, a $125 2.5" 100cell Magnaflow which to me is a more familiar brand? And also this 2.5" Stainless Steel Outlaw 200cell with an extra layer for reinforcement from scrubs.. Not that you can really bash they cat since it sits up in a nice channel on the Octy.
