Cheers for the directions and photos, im there tomorrow.

Hungrytang i have the same setup as you but prodrive sports cat and decat up pipe. let you no how i go.

 

Is your car a WRX or an STi?

Just wondering because I also have the Prodrive Sports CAT and decat to go on my STi and I am curious to see what results you get. Mine is going in next week.

 

mines a wrx. let you no the results though.
After i fitted them on sunday it does seem to rev up easier, and can notice the difference. Havent gave it too much though, waiting untill tomorrow.

 

Is it ok to just change the downpipe and not the up pipe??

Has anyone else got the same as me eg. Decat/sportcat down pipe and standard up pipe?

Is it bad for your engine?

 

I think it would be fine, dont think it could damage the engine in anyway. would of thought alot of people have just the downpipe.

As i could fit the bits myself i just wanted to get them both done.

 

I ran a decat down pipe for ages with a stock up pipe, in my 02 WRX, really felt an improvement when decatting the up though

 

hi i was thinking of getting mine done but its an 06 wrx and its pritty standard its got a ninja exhaust and a bailey dump valve so what sort of figuires will i be looking at .
i know it wiil mess up my warrenty but i was wondering how they will be able to tell if its been mapped
cheers

 

Speak to Zak @ Mocom mate (mention this thread), he will be able to give you all the information you require.

 

cheers mate

 

Ive just had my new H&S downpipe decat and prodrive centre decat fitted ready for remap on Friday.

There is a lot more turbo noise....... Which sounds awsome.

And its not too loud which will please the wife.

Also it seems to rev a bit more freely.

Roll on Friday....

Whilst I had the intercooler off I ditched the DV12 Dump valve and refitted the standard unit. As it was doing my head in.

My god I must be getting old........

 

Nice one Hungrytang

 

I've got the full PPP exhaust on my WRX. Kept the standard uppipe and the only cat is the sports cat in the prodrive downpipe.
Made 202bhp at the wheels before the remap

 

Still aint got my figures from Zak yet

 

I did remind him.

 

Cheers Foz

 

ok - done an up to date dyno run of mine with a breath of Mocom Magic dust

This was on Tesco 99 no octane booster. 13C ambient and about 2/3 tank of fuel.... as with frayz' figures - these are at the wheels

This is with current Mocom map as a before figure for mapping next week when we will increase the fuel pressure to get more life out of the injectors

Really tempted by this.

Rang Zak this morning to enquire as to the extra costs of the spark plugs and fuel pump, and as to what power gains I should expect. Considering the outlay the gains dont seem too great , not in my particular case anyway

Come on guys, need my arm twisting a little bit more

 

you can add me to that list booked for march 9th

Its not about peak figures.... its about the area under the curve. That's what makes the difference to the speed, driveability and rapid progress on the road/track. Peak figures only have a use in the pub and there will ALWAYS be someone with a higher figure than yours. I would forget the peaks and concentrate on what matters

Do it - you will not be disappointed

convinced yet?

 

Pretty much

 

Mines got a Prodrive one so need Zak did fit Denso Iridium plugs as part of the mapping though, i assume he's doing the same with yours ?

 

I think i may ask him to change the plugs on mine while its there

 

Totally agree, the cars a totally different beast to drive now, it pulls in 5th like it used to pull in 3rd, best money i've ever spent on it

Convinced yet ?

 

I want pub talk figures though

 

Amount of stuff u got going on with your car cookie you can boast about number of things fitted in one go, let alone BHP figures
