I hoping to get my blobeye sti uk up 2 350bhp, would an up pipe and ported standard headers be required? If so if I later decide in the future to aim for more eg. 400bhp would the ported headers and same up pipe be required or would they need to be modified or different ones?

yea it is to the south of ireland how do i get in contact. Thanks

I have to vouch for these uppipe ! Stuck one of the 3 bolts on from alyn to my rcm headers and really do make a difference ! Easy 400 rpm difference through the range !

Had mine fitted this week and can instantly notice the difference. Highly reccomended here too. Thanks again

Hi just wondering what are diameters on trick pipe? Thanks

there is no "one size" as we do various fitments and sizes dependant on your targets

best to contact the office direct for further info / purchase

Great service from As performance when I ordered mine, great prices and fast postage.

Little constructive criticism though, I had to open the holes up slightly on my turbo and on the gasket as the spacing on the up pipe holes wasn't quite right. Nothing too difficult but just worth noting.

we had a minor issue with one batch of laser cut flanges but still work perfectly..............

always available

twin scroll application? or maybe 1.5?

have had some slight cost increases and a v.slight re-design to accomodate which has meant the prices have had to be adjusted

Im very interested in one of these up pipes for my blob WRX would i need the map tweaking though? - thanks in advance.

it would certainly require a map / AFR check at min. as they tend to pull the boost in earlier and hence can run lean if left as std......

Just messages you on FB aswell but want to post here aswell.

Just removed stock headers on my bug and want a set of your ported and wrapped headers to go with my already purchased trick up pipe. Is this something that you can do?

sorry we are too busy to supply wrapped headers these days but yes ported headers are an on-going supply..........

various Harvey Smith "trick" up-pipes available off the shelf

How many different versions of up-pipe and what ranges of HP/TQ do they best support. i.e. if I've already got an up-pipe for a 400/400 build or a 450/450 build would I need to change it out for a 500/500 build?

Thanks!

yes we offer various options, best to contact the office direct as it varies for turbo and exact manifold being used

Do you do headers and u/p for a 2016 sti and if so what's the price please , looked on your website but couldn't find any info on them ,
Regards
Stew
