hks downpipe

[brodierx7]

if i get a hks downpipe will i need to get my pfc remaped again? will a down pipe make much difference to power? where can i get 1?:3Confused

It does depend on the rest of your exhaust system, if its a free flowing system from downpipe back then a HKS downpipe will increase the flow, therefore on your map you may suffer from boost creep or spike !!

If however your running near stock exhaust then the downpipe will only free up some flow. So you could run the risk but i wouldn\'t.

Where to get one depends on how much you want to spend, they do come up on ebay and in the for sale section every so often. If you want to source a new one then RHDjapan, or any of the specialists should be able to point you in the right direction.

I have a second-hand one cheap if you want it. Bit of surface rust but sound. I had it on a car with a decat and not even an aftermarket ECU and it ran fine, the car only broke cos I crashed it hahaha. Not that I\'d advocate trying this, if it were me I\'d want the map looked at just in case, it\'s just I knew less then. Ignorance was bliss :rollin

the exhaust is staight through and been mapped for that, does a down pipe make that much of a difference that i would need a remap again if i fit a hks downpipe?

I would take that of Nik if I was you !! I did say they come up but not that often  :mmmm.

To be honest every car is different, because you have had the map for more exhaust flow, you could be alright. depending on how conservative the map was will see if you get any fuel problems, and depending how well your boost controller regulates boost. If you see any problems then drive it carefully until you get a few more mods under the hood and get it mapped again.

Hi Nik i would be happy to buy yours, how much u want for it?

[Nik da Greek]

Well, it looks like this atm;


As you can see, it\'s surface rust but I guess due to the condition I wouldn\'t want too much for it


No cracks or damage to the important bit;


...and a nice big gaping orifice the other end


If you\'re still interested, would £50 plus the postage seem acceptable, given it could do with a good clean-up? That\'s probably about half price over what they normally go for.

Is its hks?

[Nik da Greek]

Well, it\'s not marked but I\'ve been told that\'s what it is by several people who know about such things. I think you\'ll find all the downpipes for twins are pretty much the same, just with different names on them; Amemiya, FEED, Border, TFR, Fujimura etc are all identical because they\'re made by HKS and then logo-ed up by the shop selling them.

If you don\'t want it, no problem, it can carry on sitting on a shelf in the garage, no skin of my nose dude

the hks downpipes are not labled \'HKS\' they have a number stamped on it though which can be googled.

Niks one does look hks and even surface rusty thats a bargan lol

[brodierx7]

ok nik i will take it! how do you want payment?

[Nik da Greek]

Well, Paypal\'s as good as anything if that\'s Ok with you? If you could make it a gift though so I don\'t get nobbled for fees that\'d be grand. I think postage will be about eight quid, if that\'s cool? My Paypal addy\'s   nick.liassides@ntlworld.com

Do you want be to whizz it over with a flap wheel, knock the rust off before I send it? That way all you have to do is give it a quick lick of ultra high temp paint and it\'s good to go. Or just let it get rusty again hahaha

[brodierx7]

yea that would be perfect!:Thumbs-up so i will send a payment of £58 to you through paypal.

[Nik da Greek]

Cheers, that\'d be groovy! Don\'t forget to include your address, yeah?
