Car Forum / MINI / May 2004exhaust systems
Gday all is there any real difference between using a side exit exhaust system or centre exit? Is the fact that a centre-exit system will be almost straight better or worse than having a few bends like a side exit system? I was going to buy a centre exit system, but was told that the decreased back-pressure might cost me some torque...???? is that right? thanks in advance Geoff > Gday all > is there any real difference between using a side exit exhaust system or [quoted text clipped - 5 lines] > thanks in advance > Geoff By the time the gases reach the first bend, all the power loss has already occurred. If I remember correctly, David Vizard established that the ideal exhaust for the A series was about 3 feet long! There will be absolutely no difference in performance between centre or side exit exhausts. One word of advice, unless you are going racing with a fire breathing motor, don't buy an exhaust bigger that 1.75" diameter. If you do, you are likely to loose power.

The lower the back pressure the better.

It is still, after many years, the system that all others are measured against. If you want best performance, forget all the fancy big bore stuff, use an RC40.

My not fit under the car snug either. |
