steady_dave Posted January 2, 2009 Share Posted January 2, 2009 Right, the time has come to MOT the Supra. I've had it about 2 months now and all seems well so really don't think it's going to fail. However, the car has an aftermarket exhaust with a 3 inch pipe fromt to back with 2nd de-cat. The Cat on the manifold is still in place however: 1. Will this still adhere to MOT emmissions regulations and 2. Will it pass noise restrictions with this in place...it's quite loud! Quote Link to comment Share on other sites More sharing options...
supraspeed Posted January 2, 2009 Share Posted January 2, 2009 i was under the impression it will pass with one cat or both cats in place Quote Link to comment Share on other sites More sharing options...
Benjy Posted January 2, 2009 Share Posted January 2, 2009 It should go through the BET (Basic Emissions Test) with one cat, and the noise is pretty much down the to MOT testers disgression. There is a RFR (Reason for refusal) for "Vehicle much louder than a similar vehicle fitted with a standard silencer", but tbh, unless the tester's a PITA, it should go straight through.

Dazzi Posted January 2, 2009 Share Posted January 2, 2009 2nd cat in place usually passes emmissions, not sure with the 1st cat though. Some garages can be quite picky with loudness etc Quote Link to comment Share on other sites More sharing options...
supraspeed Posted January 2, 2009 Share Posted January 2, 2009 its one of those "who you know" situations ive never had to put a cat back on or silence an exhaust noise Quote Link to comment Share on other sites More sharing options...
steady_dave Posted January 2, 2009 Author Share Posted January 2, 2009 Ah nice one guys cheers for the info, the guy who does it is a family friend. Just don't want to put him in an awkward situation. Guess we'll find out, lol. Thank you! Quote Link to comment Share on other sites More sharing options...
DaveR Posted January 2, 2009 Share Posted January 2, 2009 My car passed the emissions test and everything else to boot with a 2nd decat and an HKS Super Drager exhaust, which sounds similar to how yours is set up. And that wasn't through a family friend or anything else. You should have no dramas. Quote Link to comment Share on other sites More sharing options...
