Karlp Posted September 13, 2011 Author Share Posted September 13, 2011 Karl - please please please go and do some reading - SEARCH IS YOUR FRIEND Vik, you sound like lexx , I did just checking if you do get any bhp increase 5-10% and is torque much better? Just trying to see what you would recommend for a noob? Quote Link to comment Share on other sites More sharing options...

Vik54 Posted September 13, 2011 Share Posted September 13, 2011 If you have read around you will know that without the Uprev you are unlikely to see any consistent long term gains We love having noobs asking questions - but I think out of your 300 odd posts at least 200 must've been questions - c'mon luv do some research Quote Link to comment Share on other sites More sharing options...
Neilp Posted September 13, 2011 Share Posted September 13, 2011 karl, the decats will give you lots of rasp and rattle like you heard from my exhaust. Don't forget I did have the scorpion exhaust which is pretty raspy itself. You wont make anywhere near as much power as you expect. I made 305 with a plethora of stuff done. The stainless headers you have usually show a better gain but usually not cost effective due to time to fit. As they are already fitted then its a win situation for you. However, to see any power gains you will need a remap as the ecu will map back to factory settings after it realises stuff has been tampered with.

Karlp Posted September 13, 2011 Author Share Posted September 13, 2011 Sorry guys, as you can see I'm a bit impatient but appreciate the replies too I know a uprev remap is the way forward for any sort of lasting gains. Will crack on with the research Quote Link to comment Share on other sites More sharing options...

Karlp Posted September 13, 2011 Author Share Posted September 13, 2011 Thanks Neil The sound your zed makes is pretty sick! So think a decat is worth a £150 punt for some more rasp? Quote Link to comment Share on other sites More sharing options...
Neilp Posted September 13, 2011 Share Posted September 13, 2011 Thanks Neil The sound your zed makes is pretty sick! So think a decat is worth a £150 punt for some more rasp? it suits some people and doesnt others I really love the sound of my car especially under load on full chat. Pm Zmanalex and see if he has any laying around as if he has the will obviously be of a suitable quality. I have cheat japspeed decats and I know the will eventually crack and need changed. Horsham Developments also do a resonated type decat also for a decent price. Quote Link to comment Share on other sites More sharing options...

Dblock Posted September 13, 2011 Share Posted September 13, 2011 Silenced decats don't rasp but straight decats might. Decats have made my mpg a lil better and it feels faster too. Quote Link to comment Share on other sites More sharing options...
Wasso Posted September 13, 2011 Share Posted September 13, 2011 I don't have any rasp from the japapeed decats, but wonder if that's because of the xyz pipe Quote Link to comment Share on other sites More sharing options...
Neilp Posted September 13, 2011 Share Posted September 13, 2011 I don't have any rasp from the japapeed decats, but wonder if that's because of the xyz pipe its more a rattle I have when letting of the throttle or using engine braking. The scorpion is raspy with normal cats lol Quote Link to comment Share on other sites More sharing options...
evilscorp Posted September 14, 2011 Share Posted September 14, 2011 Hdev silenced decats are brill but my car is as loud as I wuld want it. Its worth building ur exhaust in stages so you can get it to your taste, ur manifolds will be even louder! Quote Link to comment Share on other sites More sharing options...
