Ideas To Protect Low Slung Exhaust

[Flintstone]

Right you lot. If you're so clever help me with this one

I had a 4-2-1 manifold made up for the Banham but as I've lowered the suspension ground clearance is minimal.

So much so that the insulation wrap has been scraped through in no time at all. I suppose I need a bash plate or protector but a big plate fixed to the chassis would reduce clearance even more.

I could just leave the lowest part unwrapped and secure the insulation either side. I know this will create a hot spot but will it cause problems?

Couple of steel plates under the engine mounts????

That's still reduce the clearance.

I may have to raise the suspension again but these things look really gappy around the arches unless they are low.

But won't that raise the engine slightly and therefore the manifold ground clearance?

What's the main problem here - grounding low slung exhasust or trying to protect underside of car from hot exhaust?

If it's the latter then try aluminium backed asbestos or similar stuck to floor above exhaust rather than heat wrap on exhaust.

If it's the former the best you might be able to do is to fix skid plates to the exhaust to make sure that you're at least hitting with a sloped face rather than an upright one.

I had a TVR with only 3 inches of ground clearance (due to many mods, including large diameter exhaust system) I had skid plates welded to the exhaust boxes in the appropriate places and although they would ground, it would push the exhaust up on its rubber mounts.

However if you are grounding the manifold then thats a different matter as in quite short time you will end up cracking the manifold at the headers (or at least braking the welds)

I can only suggest that you look seriously at raising the car on its suspension (or making it firmer) , changing the manifold or driving more slowly!!!

How dare you suggest such a thing on this site? Now go and wash your mouth out with soap and water.

Beat me to it Lexsport!!

Sorry Ex-Biker, I mis-read your reply. Raise the engine, hmm maybe.

I'm going to have to do something otherwise as grahambell says I'll end up doing some damage.
