I am in the process of dropping my MG but <>2.5" and fitting competition leaf sprrings etc ...

However, my housing estate has rather mountainous speed bumps. The lowest part as I see it will be the exhaust centre box. I have read this can be removed and replaced with a straight piece of pipe. Has anyone done this ??????? Any concerns ... loss of power ??

Thanks

Andrew

You won't lose power, you will probably gain slight amounts, but don't get excited you won't feel it, you will however end up with a horribly noisey exhaust.

The owners club sell a stainless system with a bomb centre box, this damps a bit of the noise and provides far better clearance, but I warn you it is still unpleasantly loud and loses that B sound.

If your centre box is catching it sounds to me like the exhaust is not fitted correctly tbh.

I've got a club stainless steel exhaust with a bomb twin pipe rear silencer and no centre box. I use the car for everyday use, 70 miles round trip on dual carriageway, B roads and white lanes.

It's a little loud at motorway speeds, but drownable out with the stereo. It's fun the rest of the time, has a tendency to set off sensitive car alarms in car parks and narrow streets and gives a pleasant bark.

Because it's a straight through system, that and the lcb manifold, stage 2 cam, freeflow head, 1 3/4" SUs with hot needles, balanced and lightened crank, K+N air filters, lumenition electronic ignition etc etc I'm getting 105bhp at the wheels. It's still only an 1850, having heard stories about the 1950s being a bit weak.

I wouldn't have any qualms about using the exhaust; the guys down at the MG / classic car garage love it too.
