Got mine custom made last week, getting tuned on Friday. I think Brad @ JMR still has a couple more to build if anyone's interested. The only other options are ~$800 for a Miltek @ Redline or +$1.5K for a Zero Sports from somewhere like RHD Japan.

Any idea what sort of performance you are expecting from this? The factory one is bell mouth, unless the cats are a massive restriction it doesn't look to bad.

Would you do this front pipe first, or do the cat back?

Do you know much much he wants for these?

Cats [sic] in your exhaust are usually a pretty bad restriction. Historically, the downpipe (front pipe) has been where people have picked up the best bang for buck. I can't imagine a cat back would give you much more than noise.

Its a restriction and no restriction post turbo is good. The inner diameter of muffler is often a major cause of egbp.

Hey bud, i asked Cobb Performance the same question a while ago and this was their response (keep in mind that my question was whether or not it's worth it for me to buy their $2000 catback exhaust or if i was better off buying just a downpipe.

"Honestly, the real restriction is in your downpipe, so I would definitely start there. Once you do that, your cat-back isn't really going to cause any restrictions unless you have well over 300hp, so it would mostly be for sound in your case. If you're looking for power only, I would suggest saving getting a cat-back until later and doing all of the other things you were talking about."

Man, I should work at Cobb ...

Haven't paid yet! But somewhere in the region of 500-600 fitted. Send a PM to JMR on Facebook if your interested.

I'd do both if you could at the same time, it'll save on labour especially with a custom jobbie like this one. TBH tho I didn't because I was so sick of the anaemic sound from the standard exhaust but I didn't have any other options to fit a down pipe at that time.

I've only done intake and this DP into a 3" Blitz Nur Spec catback. I'm hoping for anything over 200kw @ wheels but ofc depends on other factors. More of a future proof when I change the turbo in a year or so.

$200 and you can have an s204 down pipe

or around $600 for a fully custom pipe.

Thanks for the info Nik10. Which turbo does the Version 11 STI run? Looks like it's still using the P25 exhaust housing?

The P25 is the BB housing isn't it? Unsure on the VF37 housing P#.

Yip, are they still the same DP flange though? Just double checking this pipe will fit onto the back of my VF36/P25. Flange looks identical in the pics.

Just had a quick search to see what else is around. This would be about $575 landed, would take a few weeks though. That's an expensive brand though, i'm sure there are a few cheaper ones around.

Yea will fit just splitter difference may vary if fitted with one.

Not for JDM twin scroll though. Tomei did make one for JDM GDBC/D which is shorter than the Version 11 pipe, but it's been discontinued and no one has stock left.

[topza501xx]

I'm going to guess that only the Miltek one will fit a V11... and it has no cat which may be an issue.

Have a quick search on TradeMe, Not my cup of tea TBH, would rather stick with a high end JAP product over Chinese / Australian / American. Tomei expreme ti cat back is on my list first, will have to wait before I get a down pipe because I cant afford that and a tune at the same time
