Catalytic converter
#1
Has anyone any experience or thoughts about removing the catalytic converter from an Impreza Turbo? A performance co. is offering a straight thru' system that does away with the cat., releasing 20+ bhp...

Thanks for your reply...yes, I am in the UK and, off hand, I think you're right about the MOT. I queried this point with the supplier and the reply was "well, you could always put the cat. back on for the MOT". Re. the emmissions, in their experience they (the emmissions)would still be within legal requirements. My Impreza is 1 year old, so I would have 2 years to play with it, but is it worth the hassle after that.
I was wondering whether anyone has had experience of using a road car without the cat. Re. the issue about leaded/unleaded petrol, I wonder how environmentally friendly cats. are, anyway. But that's another story.

I've been running a MONGOOSE system for a year and a half(see JANSPEED EXHAUSTS QUERY),having had to refit the old exhaust back for two MOT's so far(I find this takes a couple of hours or so) and I'd say it's certainly worth the effort in relation to the performance gained.The only possible problem I've encountered has been that the system does hang rather low making it somewhat vulnerable(though I've yet to ground it in everyday driving)

I de-catted my Renault Alpine A610, I could do this legally because it was made prior to the cat law restrictions 1992J K reg plus require cat legally.
However my car abslutely walked the emissions test at MOT time with no mention from the MOT testing station.
Don't make work for yourself if you take the cat off, only put it back on if the testing station fails it because of its absence, re-test is £5.00 I think?
