ebay would be a good start. you`d need to have the cat on for an MOT so it depends whether you want the hassle of changeover every year

The stubby won`t give much BHP, just a throatier noise. Full decat would be needed for an increase in power, plus you`d need an o2 sim to fool the engine into thinking the cat is still there. The o2 sim goes between the 02 sensor and the exhaust manifold

thanks is the o2sim easy fit and is the vei the only civic with a cat on the manifold as i have seen decat pipes for civic.s. is the vei hard to tune if so do u know which 91 to 95 civic is best for tuning besides the obvious vti many thanks shaun
