japspeed manifold and decat pipe

A mate of mine has one. Not bad quality and made half decent gains when it was rolling road setup. You pay for what you get , but there is alot worse out there....

By looking at the picture the de-cat is all in on the mani so the whole thing will have to come off.
I have been told that if you put your car in for a MOT with no cat, but you put a £10 or £20 note on the passenger seat some how the car passes emissions..... strange that one ;)

yes i heard that one to, will give it a go when it comes to mot time
 
Only if you have the car 'mapped' to run with the mani (so that means a Hondata ecu or other brand), otherwise the engine will run lean and thats not good, but yeah with a mani it will be a better improvement that just a de-cat.
 
Japspeed are well known in the scooby world, and they have just become traders on the MLR.

Not sure on what to make of them tbh, a decent Evo mani is about £800, japspeeds mani is £150... :lol: :freak:

nah just the 02 simulator that screws into it my check light would come on now and again but its just a case of pulling out the num 6 fuse i think and reseting it takes about 2 mins tbh
theres a lot of scare mongering about it will run lean etc but naturally the type r s run rich anyway so dont worry about that i had it on the rollers and the tester says it was fine :twisted:
