I have had my exhaust for a while now, but one problem with it from the start has been the rattles. It shakes,knocks and rattles untill it came to the old zipties!

 

has anyone had this problem before?

 

My exhaust has been bent over the diff to suit like the factory one but its soo hard to get wright.

 

I'm thinking of geting it changed to under diff so theres not so much complications!

You have to make sure that the exhaust hangs freely and does not rub on any part of the body/drivetrain.

Then use the original rubber hanging mounts, if they are not used then I would not be surprised that it is rattling.

Yes it is quite hard to do as I have done a custom exhaust myself, I am in the proccess of modding it to fit better.

I wouldn't advise on uder diff exhausts as you could ripp off the exhaust if the wheel drops too mutch and there isn't alot of clearance to do it anyway.

 

Are you able to mod the system yourself? If not you should learn! It really isn't that hard to do with a hacksaw and welder.

A cutoff saw and gas Mig help even better :)

nothing wrong with over diff exhausts....

 

i have 2.25 over diff in the ke70, car is just legal height (only just). and ive never had a problem with it rattling or anything.

 

Under diff makes NO sense on a live axel/diff car (ie ke70).

 

as much as i am a fan of DIY, in my oppinion exhausts are something you just pay an exhaust shop to do. you can get an entire new exhaust fitted properly for under 200bucks. and if it rattles you take it back for them to fix it for free.

 

if you are going to go the DIY route, you need to buy the proper bends, cut some straights to suit and should be good. thats how mine was done anyway, few off the shelf bends and a bit of straight pipe to join it all together.
