Seany boy Posted October 22, 2012 Share Posted October 22, 2012 Hey folks, well the time has come to make the most of what I have, already have a true dual system/pop charger so the next step is plenum spacer and either HFC's or decats. Anybody reccomend a decent spacer as Ive seen there's a few on the market, Also arguments for and against Decats over the HFC's. I have a sympathetic MOT man so emissions isn't a problem, if the gains are similar I would rather opt for the Decats as there 1/3 the price. Finally anybody reccomend anywhere to do the Uprev? I'm in Newcastle Upon Tyne so the closer the better but I'm leaning towards RS at the moment due to there reputation. Any info is greatly appreciated folks Quote Link to comment Share on other sites More sharing options...
Tarmac@TarmacSportz Posted October 22, 2012 Share Posted October 22, 2012 I would go HFCs if you can stretch to it as less hassle as MOT emissions test will fail with decats fitted, I can supply either. Wasso is doing a Group buy on coloured spacers. Quote Link to comment Share on other sites More sharing options...
Arran Posted October 22, 2012 Share Posted October 22, 2012 If you have a good mot tester id say go decats, mark at abbey reckons they are worth 5-6bhp over hfcs and Horsham say they got 10bhp and 8lb ft with thier silenced decats Quote Link to comment Share on other sites More sharing options...
coldel Posted October 22, 2012 Share Posted October 22, 2012 Yes bear in mind a normal decat will be louder. HFCs, the Berks anyway, also emit a rasp which is very audible. Motordyne are the spacer of choice but as the guy says, Wasso has an offer on the go. Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted October 22, 2012 Share Posted October 22, 2012 i'd go hfc's, mot regs are being tightened, which also means so are the VOSA. also decats aren't road legal so technically your insurance is void as well. Quote Link to comment Share on other sites More sharing options...
Jez @ H-Dev Posted October 22, 2012 Share Posted October 22, 2012 (edited) As the others have mentioned, de-cats will give best power, high flow cats will give slightly less power but no emmissions problem, plenum spacer give more top end power too. HFCs, de-cats and spacers in stock http://www.h-dev.co....oducts_id=25344 http://www.h-dev.co....oducts_id=25343 http://www.h-dev.co....oducts_id=25052 We do a package, which is cheaper than the individual components, if you'd like it fitted and remapped with Uprev: http://www.h-dev.co....oducts_id=25356 Edited October 22, 2012 by Jez Quote Link to comment Share on other sites More sharing options...
ewan221 Posted October 22, 2012 Share Posted October 22, 2012 Friendly mot testers are becoming fewer and fewer, its just not worth the risk for them anymore. I know a few people with TVRs who have really struggled with emissions this year where it was never a problem in past. Quote Link to comment Share on other sites More sharing options...
Parsnip Posted October 23, 2012 Share Posted October 23, 2012 Would say HFCs - simply for the abilty to swan through a MOT without any hassle Quote Link to comment Share on other sites More sharing options...
Seany boy Posted October 23, 2012 Author Share Posted October 23, 2012 Cheers guys , iv jumped on Wasso's spacer group buy. Think il stick with de-cats tho , I work in a garage so it's not a massive deal if I need to change back to the original cats for mot. Still need to get the Uprev done tho, won't be till after the spacer comes which will be December time. Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted October 23, 2012 Share Posted October 23, 2012 i wouldn't be worried about the MOT, i'd be more concerned with an insurance company voiding your policy on a crash and you having to stump up the cash as the insurer won;t pay anything. most Decats are marketed as off road use only. and if they are and they are fitted to a car they aren't technically legal. and an insurer if the car is examined which they aften are could choose to void your policy, same as having undeclared mods.

Gonzodave Posted October 24, 2012 Share Posted October 24, 2012 I agree, insurance companies are getting quite hot on mods these days. I had friends that had there insurance company come to inspect car before they insured it. Quote Link to comment Share on other sites More sharing options...
