PROBLEM! ANY IDEAS?

Hello people i need some assistance diagnosing a problem.
I thought i might have had a dying clutch on my hands as my little jimny wouldnt rev above 4000rpm and was struggling to get upto speed also the exhaust tone had got louder.

however i sat in it tonight in neutral with the clutch up and reved it towards 4000rpm when i got there it was like i hit the rev limiter it just wouldnt rev any higher!could this be a clutch issue even in neutral and stopped or is something else going on? im now thinking an exhaust issue maybe a blocked or collapsed cat? no warning lights have come on either.

im just guessing tho hence im asking you lot

It take its a twin cam engine

Start it up and feel if any exhaust gasses are coming out the exhaust or remove the cat and have a look inside it

yea its the twin cam, im assuming you mean out of the back box or am i looking for leaks along the whole system? is it easy to remove the cat ( on my drive with a trolly jack)?

Sounds like colased cat mine done this the other week

hows things? what sorta price am i looking at if that is the fault?

They have 2 cats well mine did mine was the second one along so I just nicked the rest out probley give it a beter flowing exhaust but engine light comes on they were quite expensive but on eBay there cheap and still have a warranty yer I'm good you
