Hello,
Has anyone here fitted an exhaust? Is it hard?

Iv been told you have to drop the engine..
But iv also been told that you dont have to drop the engine..

Help

exhaust fitting is relatively straight forward with no need to dropping the engine out. what exhaust unit are you fitting ? standard mini or performance ?

Peco Straight through

I thought i would be hard seeing as the engine bay is like really small

Without the engine in place and the manifold fitted there won't be anything to actually attach your new system to at the engine end. Fitting is pretty straightforward, virtually all the work is done from underneath the body of the car rather than in the engine bay

Yeah thats the only part on worried about is getting the manifold off and putting new one on..

It's fairly easy using a few 1/2" sockets, extensions and spanner.

Does your new system include an exhaust manifold?
Do you also have a new inlet manifold to fit?

To remove, take off carb, remove exhaust clamp at back of engine and drop the pipe downwards.
Then undo the engine steady, allowing you to rock the engine forward to take the manifold off.

You may find it easier to remvoe exhaust studs then lift the manifold straight up.

It's fiddly and awkward, but it's the only way to do it really - you'll never fit the manifold to the engine whilst its out of the car and be able to lower it in as one unit. I fitted my manifold a couple of weeks ago and found that with the top engine steady undone there was enough movement to get it in place OK, just be patient with it.

It a Full Peco Big Bore Straight Through exhaust system..
So yes its the full system..
Is it a home job or a garage job?

A full system doesn't normally include the manifold

Have you got an inlet manifold too? As the standard inlet and exhaust manifolds are itnegrated, if you are replacing one, you have to replace both!

Exhaust change is an easy job at home, especially if you have a pair of them little ramps to get the front up a bit, (helps when dropping the old exhaust out, then you can just extract it from under the front of the car.

What sort of manifold is it? Even with ramps I found that I didn't have sufficient room under the car to feed the manifold up from below. As it was an LCB, if found it much easier to fit by removing the Y peice at the bottom and feeding it in behind the engine from above in two parts, then connecting it back together again once it was in place.

Have you got an inlet manifold too? As the standard inlet and exhaust manifolds are itnegrated, if you are replacing one, you have to replace both!

This is a good point, if you're replacing that standard cast iron manifold then you will need to get yourself a seperate inlet manifold too. Either that or be prepared to do some serious work with your hacksaw in order to separate the standard inlet from the exhaust manifold!! Personally I'd go with a gas flowed after market inlet though, as this will improve performance over the standard item.

You will need a new inlet manifold, assuming your car is standard. All relatively easy to fit, don't forget to use new gaskets and use some exhaust sealing paste at the joints

Yeah that's an LCB (Long Central Branch) manifold, in the pics it's already been separated into two parts (the two outer branches that join together into one pipe - on the left in the pics) & (the single central branch that is a separate pipe - on the right in the pics) both pipes are then held together by the Y-piece, that has been clamped onto the end of your exhaust in the pictures.

You will also need a manifold-to-gearbox steady bracket (that connects the manifold to the back of the gearbox), as I can't actually see one in the pics. If you fit it without one premature breakage can occur due to engine rock.
