The manifolds will improve the whole package, there are gains to be had there. At £330 they are a steal and are on my list for 2009.
Likewise. I think my mods for the START of the year are going to have to be mannis and a quaife diff. Am also looking into getting a new set of wheels for the beast which will allow me to refurb the ones i have on at the moment and get some decent track tyres to fit to em.
so just to confirm all this what bhp gains are to be had with the manifolds, de-cat and cat/de-cat back. around 10-12bhp i would expect to see there. and a total of what, £700???
in my opinion the mani's make alot of difference, seems more willing, maybe it shifts the torque im not sure...but worth the money bud...they sound so raspy, gorgeous sound, hhmmmm :-P
i think between 185-195bhp would be a good figure to get from having "the full package" (including induction kits etc..) but of course it all depends on engine variance.....they are built to a fairly close tolerance....but technically speaking not all of them are going to be bang on 179bhp.....be less or more....so its hard to judge...in my opinion....fitting the full works to my car was worth every penny.....strongly recommended
a cat back will get you next to nothing in the real world. Changing the manifolds and Cat are the only real ways for getting more power from the exhaust
Spot on, the induction system on a 180 is the most restrictive thing.
