Because you already have the RCMS 3 bolt header set there is no contest. Simply fit the special 3 bolt uppipe, cost £149, get a remap. Job done and report back on how much quicker your turbo now spools and how much torque you have gained.
You are at a fine dividing line as to where you choose ported headers or the tubular RCMS but because you already have the RCMS tubular the decision is very easy and relatively cheap.
It would be good if you could compare before and after dyno graphs providing they are from the same dyno. Do you have an existing graph for the current setup?

Overnight delivery is £12.50. It comes to you wrapped with five new studs and ready to fit. Reuse your existing 3 bolt uppipe gasket.

Make sure you give me your name, address and what it is you want. Job done. You get it next day.

If the only modification since your remap is a swap from the supplied uppipe to my uppipe and on the same rollers then I suggest you put your graphs on here.

Do these pipes come in twin scroll as well?

Grant there is nothing wrong with the twin scroll headers as supplied OE so I don't see any point reinventing the wheel. I only want to design, prove and make things that give a genuine benefit.

Happydude: You also have a no cost option of uppipe with a boss or without. The purpose of the boss is to take an EGT sender or whatever so you don't have to hack the uppipe about to achieve that.

whats a an egt sender harvey or shoudl i be speaking to my mapper stroke builder about this

exhaust gas temperature sender mate,tells the ecu how hot the gases are or commonly known as cat on fire sensor.

Some people fit EGT guages to show exhaust gas temperature. If it is located in the uppipe you need a boss to take the sensor.

Did this a few weeks ago :) just need to get back to same RR to check difference. Feels better though ;)

TX.

have you have it dyno'd yet?
