Japspeed Headers and Up-pipe
http://www.japspeed.co.uk/Subaru-Imp...3/p-24-72-990/
Any one running this? be interested to get some feedback! |
I run the spec 2.. one of the large 22mm nuts wound itself loose, so make sure you loctite it (its in the 4 into 1 section). Other then that, good fit, and work well!
|
nice one cheers mate!
Any one else got any views on these? How restrictive are the standard Headers? |
Standard headers arnt to bad. Good up to around 400hp. The japspeed ones are said to be not to good. Id suggest doing a search
|
Im looking to run 350bhp on a WRX with a TD05 18g, so I can keep the std headers and maybe just get a Harvey Up-pipe?

Edit: For example, if you had a 300bhp STi with standard Turbo, would you stand to gain anything from headers/up-pipe and remap? |
ported headers and custom up-pipe would certainly assist - majority of aftermarket headers and particuarly the up-pipes are far too large for std style turbo's IMO
|
I'm planning on going ported headers + HS Up-pipe within the next couple of months; along with a decat turbo-back and remap.
I'm not expecting too many gains, but it's all ground work for a larger turbo later in the year/early next year with potentially a FMIC. It seems from reading, that despite changing exhaust, intercooler, headers and up-pipe - only the Turbo is actually giving significant gains, and the rest is all just "support equipment". If I keep all the "support equipment" standard and just bolt on a turbo good for 380bhp, and make 380bhp on the dyno - would I gain more with the same turbo plus headers, up-pipe, intercooler, exhaust or will I make the same power, just with a better driving experience (less lag, etc)? Sorry for the thread hijack! |
No worries on the Thread Hijack mate , as I'm learning and taken it all in as well as I would like to know!

As above. I fitted a set of headers in my early days of ownership to a mapped car with a standard turbo. Had the map tweeked and lost power and spool as the up-pipe was to bigger bore.

I'm running japspeed headers and de cat down pipe, fit was not great but got them on.
I ported them aswell. Massive gain in torque over standard headers. Big d ported my vf35 aswell. Here is my graph from lat sat. Before map was standard car at chritmas with a re map. Cheers Chris Attachment 57789 |
