Gazboy Posted February 2, 2005 Share Posted February 2, 2005 Hi- did a search, but it didn't answer my question, so sorry for a potential re-post: If you remove the second cat, but leave the first on, will the car still pass the MOT? If so, if you leave the first cat on, could a Blitz SBC raise the boost over factory? What is a quiet, yet decent breathing exhaust? (cat-back- can't have loud stuff as my wife has a major hearing prob) Instead of using a FCD- could a GReddy E-manage be used instead? Would it be better? Would it be more cost effective to use a Blitz ECU (like that one on Fensport) than an E-manage and a boost controller? Cheers. Quote Link to comment Share on other sites More sharing options...

Yes a boost controller will be able to raise the boost, would get the Greddy E-01 Boost Controller if you are getting the e-manage as they can be linked. 3. You don't need the FCD if you have the e-manage fitted, definitely better but more expensive. 4. I would definitely recommend going with the Greddy e-manage and Greddy E-01 Boost controller.

SimonB Posted February 2, 2005 Share Posted February 2, 2005 If you're only going to remove one cat I would take the first one out and leave the second - the first one is the more restrictive. That's what I did originally. Quote Link to comment Share on other sites More sharing options...

That's what I did originally. I agree. Also the cats retains a lot of heat so taking away the one nearest the engine is probably a good idea. The only downside is that changing the front cat is more difficult than changing the second one. Quote Link to comment Share on other sites More sharing options...
Gazboy Posted February 2, 2005 Author Share Posted February 2, 2005 Will it still pas the MOT? Quote Link to comment Share on other sites More sharing options...
SimonB Posted February 2, 2005 Share Posted February 2, 2005 Will it still pas the MOT? Yes, mine did (just). I have a *friendly* MOT place, so it passed the last time too, despite having no cats at all, but it passed the time before legitimatly with the 1st cat removed.

Jake Posted February 2, 2005 Share Posted February 2, 2005 Yeah. On my 93 RZ I just put the second cat back on for the MoT and take it off again immediately afterwards. Quote Link to comment Share on other sites More sharing options...
