so im putting my old stainless on my 1600 tomorrow as the original one off a split that the engine came out of i dont like so mine is going on but talking to a mate he says sometimes it can mess with the engine when changing over and putting stainless on like running funny and chuggy :\ what would this be down to ?
It would be down to your mate not knowing what he's talking about . If the stainless physically fits, it should be fine.
Have a go. You may find the exhaust doesn't fit. Getting the manifold nuts off may be tricky, so take it easy!
Stock style stainless or 4 into 1 stainless (quiet pack etc) type? If the former nothing will change, the latter could possibly (though probably not noticeably) make the engine run a little leaner due to the freer flowing nature of the exhaust.
yeah i get what you are saying its a 4 in 1 also cos my bus is so slammed it has worn a small hole on the edge of the back box now i dont think its worn thru into the box i think its just worn on the weld but looks like a hole now if it was would that do anything ?
