Cementing a long established association with the various companies previously involved with manufacturing the intensively developed Harvey Performance “trick” up-pipes and ported headers for the Subaru tuning scene, AS Performance has established the exclusive rights to continue their supply.

As a tribute to their creator Harvey Smith, who sadly passed away in late 2012, they will continue to be called the “Harvey” up-pipe

available in std fitment and 2bolt & 3bolt GT Spec style for improved spool and responce

What price are we looking at for the Headers and Up-Pipe?

I'm looking to replace mine and am searching and reading up on them.

 

trick up-pipes start from £156inc./fully DEI heat wrapped and with 5x new studs and delivered to std UK postcodes

wrapped and ported headers £265inc./wrapped (delivery extra) although we discount them when bought as a "set" with the trick up-pipe........

we currently do on an exchange but we are revieing this as i have had a lot of enquiries from Europe, etc. which makes the "exchange" more difficult - may well have to look into costs of "kits" but this will obviously add to the final bill................

as with most of what we do its probably easier to contact the office for a specific quote/enquiry

 

2 bolt and 3 bolt "GT Spec" fitments also available at £165inc./fully DEI heat wrapped and with 5x new studs and delivered to std UK postcodes

 

Still hoping that there will be "kits"... :/

 

kits are "in hand" and can be offered on an outright purchase basis now at the extra cost of a set of std headers (sourced s/hand)

 

Excuse my ignorance but what exactly is the benefits of a 'trick' up pipe?

Also if I were to send my headers to be ported and wrapped would I be able to have my own ones back? Waiting time would not be a major factor for me.

 

The trick uppipe improves the spool of the turbo. Harvey himself (RIP) stated an improvement of 350 to 500 rpm by fitting the uppipe. Have a look at this thread to see some dynos and comments.

@Alyn: All parts arrived on monday. That was awesomely quick! Thanks again.

 

Basically, the up-pipe has a venturi feeding into a smaller dia. section which speeds up the gas flow into the turbo. It's a very old fluid flow principle but getting the combination of venturi and secondary pipe dia. right, makes it effective. It also has a slip-joint to reduce stress on the system.
I've been using one combined with the GT spec headers.

Is there a GB coming up on these any time soon need a trick up pipe for a md321t and Standard ported headers

 

Thanks for the explanations

Ill invest when im ready then

 

happy new year and back in the office from the 6th........

 

updated pricing added due to slight manufacturing/material cost changes and also to streamline the range due to the high volumes involved

std 2bolt fitment "trick" up-pipes are £156inc./fully DEI heat wrapped and with 5x new studs and delivered to std UK postcodes

2 bolt and 3 bolt "GT Spec, RCM, Lateral, etc." type fitments also available at £165inc./fully DEI heat wrapped and with 5x new studs and delivered to std UK postcodes

we are the only manufacturer/supplier of the Harvey Smith trick up-pipes, please be aware of (often more expensive) poor performing copies.........

 

and to clarify there is more than one "spec" of trick up-pipe so please give full details of turbo/projected power, etc. so we can match you with the correct fitment

 

Can you convert a rcm twinscroll up pipe to a Harvey one?

 

cant say i have much knowledge of the RCM one?? quite happy to look at any possibilities.......

 

Hi brought a complete set up from Dawn when she was selling some of Harvey's bits it consist of a billet gt30 twisted up and down pipe and gt spec headers my question is the headers and up pipe are only 2 bolt my concern is will these blow as I will be using these on a track car I new at the time of purchase there was two bolt but thought Harvey wouldn't of put these together if they would blow ?.any information would help/put my mind at ease

 

Hi, I'm gonna be after a up pipe for my 05 wrx at the end of the month. How do I order and what info do you need. It's just the up pipe that I'm after. Also, what else will I need for fitting and can you provide the other parts?

 

easiest is simply call the office with details of your headers and turbo/projected power......

we also stock any/all gaskets required if needs be

 

I just wanna say thanks for the great service. I ordered yesterday and got the delivery today. I cant wait to get it fitted. 10/10

 

no problem, happy to have been of help.......

 

Other than the improved spool from the Harvey pipe, what's the gains from the kit as a whole (I.e. Ported headers and Harvey pipe)?

 

Have a look at Harvey's website here, which is still online. Feels weird to link there though

 

just like gas flowing/porting your heads you will see an overall improvement in torque & response from the additional headers and makes the engine ability to achieve boost "easier"

 

These still going?

Thanks in advance

 

yes all available direct from ourselves as the sole manufacturer/distributor..................

 

Looking at a 3 bolt version. Do they come with gaskets?

 

no we dont include any gaskets with the up-pipes, but they do come DEI heat wrapped and with 5x new studs...........

we carry all gaskets in stock so easily added if required

simply call the office to order 0191-4103770

 

hi how much for 3 bolt uppipe delivered to ireland. Thanks

 

would depend on which Ireland your asking about, if Southern then we would have to check exact costs due to size/weight but simply contact the office and they will sort for you
