I just ordered a RSR Downpipe with the cat delete on the same pipe. I was wondering what I should do to avoid a CEL? What exactly does a 02 sensor do and where would i place it on the pipe? Would I have to weld it on? thanks for answering:P

Also my clutch is slipping so I think i'm going to get a exedy hyper single. One question is where should i go to get a new TOB? My friend said my current one is loose and therefore makes noise...are there ones that wont become loose and if so where can i order it. Thanks

 

Actually another thing about the clutch :P

Anyone have any opinions on whether i should get the hyper single or an ACT with a fidanza Flywheel? Does the hyper single come with a pressure plate?(Dunno too much about what composes the clutch). Thanks

 

The best and cheapest fix for the CEL is to get 2 18mm anti-foul spark plug adaptors from the "help" isle at Pep boys. Drill out one of them with a 1/2" bit, screw the drilled one into the other one and screw them into the exhaust, now screw your O2 sensor into the adaptor. It takes the O2 sensor out of the exhaust flow enough to keep from throwing a CEL.

Why only go Hyper single? For another $400, you could get "literally" twice the clutch with a twin plate. The Excedys come with fly wheels.

You can get a TOB from Mitsu or ACT.

If you order from any vendor, they can get all for you.

By the way, the CEL fix was given to me by BPClements, no CEL in hundreds of miles.
