Well I finnally installed my header and 17% Pulley. The car is running great. It made a word of a difference. Thanks to Alta's 50% Off Sale. I also installed Tensioner Stop, New Belt and Colder Plugs.
I also installed a test Pipe. The CEL just turned on. I guess this is because of the Test Pipe. No have read somewhere about using 2 spark plug anti fouler. Do I have to do this to both sensors?
I also notice I tell the exhaust fumes are stronger. Is this normal? Thanks

Exhaust fumes will be strong as you have a test pipe and not catalytic converter.

Yeah, that's what catalytic converters are for. I don't think it's worth it to remove it for a Mini as the gain wouldn't be much. Plus, it hurts my head and I can't stand driving behind people that are catless. And plus the whole thing about me working to save the environment....probably wouldn't go over well where I work.
Ya I think I have to put stock one back on. I bought a aftermarket that came with headers but when I shake it sound like a box of BB's. So i think the Cat broke on shipping..

my exhaust rattles too ever since i installed my headers, but thats only when i put int in 1st or reverse and only when its at about the friction point. TFor me its just the heatshield rattling a little.
Soccer I did find what was causing exhaust rattle. It was the exhaust hangers in the center of the car. The Rubber/Metal hangers have a screw on one side and are looped through the bracket on the other. I used 2 self tappers ( 1 on each hanger and it took the exhaust rattle away. I found this out by putting car on lift and putting it in reverse. (not fully engaged) So I would try that worked like a charm.
DrSilver. I think you are right. I will take a look at that this weekend and see.
Now has anyone experience rougher idle with these mods?
Thanks for all the help and ideas.

Cat = catalytic converter. Now these are made of 2 different materials. Steel and Ceramic.. Since mini coopers untuned run very hot so it will melt the steel cat and cause a blockage in the exhaust. Now Ceramic can handle higher levels of heat so you will be safe..
