Re: pre-cats
Fumes an issue for me - but going back to cats and loosing some of the power.... I'm equally not so keen on.
Not sure what to do...
More I drive the car- the more I love it's power. Couldn't go back to stock plus

He means the 20-30 BHP he has gained from having catless downpipes, he would loose it if he went back to cats.

Re: pre-cats
Just getting back to this gent's and tomboy (amanda).
I've started gutting my spare downpipes now ready for saturday morning, but one thing i noticed in the srs thread posted in here, the guy mentioned that he ''re-fit the o2 sensors the same amount of turns back in as they were removed''. Now, i'm swapping the sensors off my old downpipes onto the new gutted pipe's, am i going to have problems here?? I thought they just get put in till the threads bottom out??

Re: pre-cats
Yep, screw them in until they're tight - i've heard of people using spacers to raise the post cat sensor out of the exhaust stream to help fool it with emmissions, but i personally think this is a pile of crock... Pre (main) cat sensor should be screwed in all the way

Re: pre-cats
Yeah, I'm not sure about why those spacers would work. Get a smoother 'average' maybe...

Re: pre-cats
Could be Shopp - i know folk use R/C networks inline with the post cat o2 sensor when they've removed the cat... Presumably to smooth out the signal.
Still, would always advocate screwing the o2 sensor in tight - dont want uber hot gas escaping from there please!!
