Exhaust

[Birdsnest55]

I have a Steve Parker fitted to my station wagon, 200 TDi with 300 turbo, that has only one box but it at the very back.
I have the original exhaust in my shed, it had been fitted new but never used. I think that has only 1 box.

Didn't think there would be much difference but obviously the military one seems to be, is that exhaust for sale Paul

Leave the big-bore 2 inch stuff alone for obvious reasons. Boy-racer f*rt-can science only. If we want the 4-pots to breathe better, gas-speed should be up, not down. Better extraction, vastly more powerful cars run our size as stock. If large bore worked, 12inch bore would too.

I see SP and others sell a big-bore variant,  shall not blame them. Performance innit.... sell what people buy.

Didn't think finding a full exhaust system for my 1970 series 2a 109 ex military would be impossible

I bought a Double S from Paddocks many years ago. It's still going strong.

Me too - fitted earlier this year. Still sounds like a fart in a metal drainpipe, but burning E5 it should soon enough line the rear box with black fur and de-tinny it.

It'll soot up soon. Mine did.

If you what a good rasp try fitting a 4 into 1 manifold and a rear free flow ACR stainless back box, you can wake the dead with that.

Not really a Land Rover sound though, more like a boy racer.

It is what it is, ACR promote it so can't really say much more than that, if you have a problem suggest you speak with them.

The stock single -box is quite restrictive, the quick way to remove that restriction is 1 x straight-thru. With emissions and competitor considerations that'd also be why come the mid 80s, LR specc'd 2 x straight-thru boxes. Quiet and performance. It won't be the 4:1 doing the raspiness with the ACR set-up. That'd be ACR's straight-thru 1 x box. Two would get the noise down.

Modern systems are found twin-box for the same reason.

Mine's 4:1 twin-box, and quiet

Back in the day, the other way was to put 1 x box well forward. Does kill performance, and noise.
