gt4tosupra Posted September 20, 2009 Share Posted September 20, 2009 My cats rattling, so should i buy a whifbitz 1st decat, £160, or should i buy one from japspeed for £120, is there any difference? Or should i be boring and put a new cat in there! The second cat has already been removed, how loud would it be overall, with my Blitz Nur spec R?

supspower Posted September 21, 2009 Share Posted September 21, 2009 Agreed very loud!! I experimented and removing the 1st cat and keeping the 2nd cat made more than noise than keeping the 1st cat and decatting the 2nd! Link to comment Share on other sites More sharing options...

supspower Posted September 21, 2009 Share Posted September 21, 2009 The baffle reduced it alot for me but i prefered the noise without Havent got a clue, might be best sourcing a second hand one? Link to comment Share on other sites More sharing options...
gt4tosupra Posted September 25, 2009 Author Share Posted September 25, 2009 How many extra horses will taking the 1st cat off release? (with the 2nd already gone) 10 or 15 maybe? then i'll be closing in on my gt4 power figure:D Link to comment Share on other sites More sharing options...
Neil-NA Posted September 25, 2009 Share Posted September 25, 2009 I could be wrong but i dont think you will gain anywhere near that amount of HP. N/A cars are very hard to tune Link to comment Share on other sites More sharing options...
Missile Posted September 25, 2009 Share Posted September 25, 2009 I'm without both cats. Its loud but in a nice kind of way. Not a crazed duck waaaaaaaaaaaaaaaak waaaaaaaaaaaaaaaak. I took off my 1st cat, Bored all the internals out and welded it back up. Doubt it made much difference, But the clutch did fail around the same time (Slipping etc) so any gain was wasted in slippage. I have a spare 1st cat in the shed i could do the same too Link to comment Share on other sites More sharing options...
