_Shane_ Posted May 22, 2014 Share Posted May 22, 2014 Lads what would be the best way to reduce the emissions of my supra so it will pass the nct I have a 4'' straight through system from downpipe back, car is running a hks T51 turbo kit, hks downpipe, hks exhaust etc Would a sports cat help me pass the test. I didnt put it through the test yet but thats the only thing that i can see the car failing on (the emissions) Any help advice appreciated Thanks Quote Link to comment Share on other sites More sharing options...
Fizzy T Posted May 22, 2014 Share Posted May 22, 2014 Most people swap out their decat section on the exhaust for their standard cats prior to the test, that or have a friendly mot tester. A sports cat will help bring the levels down but whether or not it's to a level that will pass is anyones guess, The price of those sports cats are quite high too so I'll always opt for 15mins under the car refitting both my cats than £300 on a sports cat that might not cut it. Some sports cats can be found here... http://www.jetex.co.uk/website/sportscatalysts.php?eng=Turbo+or+Supercharged&hp=326-375bhp&dia=3.0+inch Quote Link to comment Share on other sites More sharing options...
_Shane_ Posted May 22, 2014 Author Share Posted May 22, 2014 I dont have either of the 2 oem cats that came with the car plus the car is single turbo now Would much rather fit a stock cat rather than purchasing a sports cat if im honest Quote Link to comment Share on other sites More sharing options...
Fizzy T Posted May 22, 2014 Share Posted May 22, 2014 (edited) Completely agree A quick look on ebay says this link is a 1JZ / 2JZ cat... http://www.ebay.co.uk/itm/Toyota-supra-soarer-cat-catalytic-converter-1jz-2jz-/271495776035?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item3f3668c723 Looks like a 2nd cat to me as it's got 2 bolt holes on each end, I'm pretty sure the downpipe is a 3 bolt hole pattern. Someone else will confirm hopefully.(just noticed it's actually stated as a 2nd cat on the ebay link haha) Sounds like you'd need the first cat too or a first decat pipe to hook up to your current system.
