What would you do first?

[martynh]

My car is standard apart from a panel filter, been thinking of either sticking on a cat back exhaust or having the manifold matching done.

Leaning towards the manifold work as it's cheaper than a zorst and more likely to get more out of the car in respect to bhp.


What do you reckon?

Well i was speaking to a forum member on the phone last night and he said he got about 10bhp and 10lbs/ft on the matching from BenR.

Thing is, power is great but you will undoubtedly get more satisfaction from a nice sound.

Scrap the useless panel filter and get a cold feed pipe with inline filter straight to your throttle body - route it so airflow is constant and not going through awkward bends. Then get your hack saw out and cut your catalytic convertor off and weld an 8 inch straight through pipe in its place. Then take your inlet manifold off and polish & port it yourself if you feel the need. You will notice an immediate difference in power from these mods. This is a budget way of uprating power on your car - there are proffesionals that will do the same but charge you for the privelidge.

Any tips and tricks on how too port and polish... tools etc? PMing me would be better as I'll probs end up I replied in this thread

I know what you mean, may be worth saving up and getting both done at the same time?

manifold matching is better for gains, you will get differant gains depending how mis-matched the manifold is

de-cat I feel is a noticeable mod as well as the manifold matching.

 

[martynh]

I know the decat is good for gains but I'm not bothered about it for MOT reasons, liking the idea of the manifold match, followed by a zorst.

Anyone had probs with the MOT and having a decat?

182's are easy to change over back to the original cat.
