Just looking at my exhaust on the V8 (series Designa chassis with coils). It is a real pain to get it down and up over the gearbox mounts so everything is out the way and not subject to grounding so........

How stupid would it be to

1. buy some laser cut flanges like these and make up some pipes that go out over the chassis rail, into the front wings and down under the sill exiting infront of the back wheel. A link pipe would be difficult but I understand that only reduces some bottom end grunt a little.

2. Reverse the standard manifolds so they point up - yes up - and have tractor mufflers out through the bonnet? I could have a kettle alongside

I have pipe bending facilities

ewww coiled series

Well I considered it myself.

Purely for ease of side exit pipes.

I thought about cutting a hole through the chassis rails and welding in a tube and passing the pipes through the chassis.

Going under without a cutout is a bad idea but I thought a hole through could be easier.

I decided against the idea with the basis of performance and off road protection being priorities.

Out the front arches is fine, I mean you can take your exhaust where you want as long as it works.

HOWEVER

Seeing as you have considered through the bonnet you are clearly a legend.

I was considering it but wasn't sure if I could get away with it

It would work and it would be awesome!

I spent a lot of time considering the merits in having two exhausts going up either side of the windscreen - like truck stacks. It would be very easy to do and would avoid a lot of pfaffing and would look fantastic. However, given that I want to drive it (an not just take to meets on a trailer etc) I eventually decided that the in cabin noise would be pretty intolerable after a while.

Mine are going to go out of the rear quarter panels now (one on each side). Not sorted routing yet but looks easy enough.

A bit radical but if you had a roll cage you could route it out through that perhaps??

some old tipper trucks (Hino for sure) had the exhaust running through the frame of the tipper boby,

Yep, it's a good way to stop the load freezing and sticking to the tipper body, lots of the larger off highway dump trucks were the same

Now that is a thought. My HM cage was only meant to fend off some trees but as the bars go over the roof not just around the screen it could work. Do ya think I will need a muffler?

I'd be more concerned about it being so restrictive.

Run each bank of cylinders down each side of roll cage perhaps?

Even so, that CDS tube is pretty measly inside diameter isn't it?!

In theory it would work of course, but I also reckon it would resonate like bastard, burn the paint off, burn your hands off when you're scrambling around the car and generally cause mayhem!

...and keep you warm in the process - gotta be done

All the same, having two stacks out the top of each wing using the roll cage as a support with the pipes going back over the roof also appeals..
In one of the mags there is some stuff on a long nose LR. Looks like the manifolds are flexible pipes joining a tube. So S/S flexipipes joining a tube which sits under the wing and exits like a snorkel?

I hate to rain on your parade, but a mate from uni did something similar a little while ago, I don't think he has returned to LZ since!

Plenty of MGB V8's out there with headers through the inner wings and running along the chassis.
Every single MG RV8 left the factory just like that too.

You can't have an exhaust through the bonnet and use it on the road. You can perfectly legally have an intake though...
Here's one I made earlier...
