Had my K1 fitted today - sounds awesome!
However, the fitter did say my Y-pipe was blowing bad - he has done a temporary bodge/fix for now. In retrospect, I should have bought a new Y-pipe at the same time to replace stock, but didnt think it necessary. Is there much of a benefit getting the Japspeed Y-pipe over stock? - And while I am at it, is it worth replacing OEM CATS?
I have read through many post tonight and whilst De-Cat seems the cheaper option, it also can mean more hassle MOT time and also a drop in torque (although this is aparrantly disputable on here??) It looks like High Flow Cats are the way to go...
Ignoring any ECU resets, what gains could I expect from 1/ Japspeed Y-Pipe 2/ HFC?
In order to save £££ in fitting - if I'm going to get a new Y-Pipe, possibly new HFC - is it worth looking at manifold as well?? - what gains could I get from a new manifold?
Obviously costs are now escalating, and I'm starting to scare myself how much this will cost me, but I look forward to any recommendations (with corresponding gains and costs) you can advise on.
Thanks in advance, Dave (couldn't find a smilie for 'looks for scissors to cut up credit card!')
edit - I say ignore ECU reset, because I have a 2002 JDM, and apparently they dont auto reset any gains (still needs confirming)
