|I'm going to get the real video camera out (decent-ish mic) and record a small amount of how it sounds currently (normal cats (x2) and nothing else but correctly length exhaust. It will be slightly tainted with the rattle against the frame, but it will give a reasonable idea.
Wednesday, glass pack should be in and i'll do another recording after that.
I drove it just under 100 miles today, once again, worked great for the job i needed this for, snow and ice :)
I will enquire further on the bearings, they're obviously not going to be as 'needy' as the turbo bearings, but they absolutely matter, so i do care.
The 3 pre-cats were introduced in either 2001 or 2002, for which mine is the latter, in the same way the engine suddenly started specifying 5w20 instead of 5w30 (guess what oil it gets)
I believe it's all Café standards related, ie. un-needed (outside of government statistics) Pre-cats are only there for cold startup, to catch more emissions when the normal cats aren't up to temp (reaction requires high heat)
This engine and it's emission control system does not take into account the 3 pre-cats, they were just slammed on their, hence the problems they cause.
Short version of all that is that the engine was never designed to run with 5w20 or with another 3 mini cats shoved against the engine - worst place for cats as far as the engine is concerned? next to it, though it's the best place so far as cats are concerned.
Rally cars have their cats right on the tailpipe piece, trust me, makes a large difference in power etc.
I didn't have to change down going up the regular hills on the way home today, previously i'd have to drop to 4th, push the pedal hard, and it'd still loose speed up the hill, now it's no problem!
Gonna make this post a little more exciting, Christmas presents, well, one for now, some lovely new 06+ mirrors :)
