N4eay Posted September 19, 2017 Share Posted September 19, 2017 Evening all, Just trying to get some kind of consensus, I've recently had my HR UpRev tunned, the UpRev software enables an option to apply a switchable map called pops and bangs, I've heard that this can destroy OEM cats, is that accurate? Ive got the Cobra res cat back fitted. I wouldn't want it on all the time, but every now and again might be a bit of fun.

Ekona Posted September 19, 2017 Share Posted September 19, 2017 Short answer, yes. Very bad idea. The odd pop here and there is cool, but a road car doing it all the time sounds ridiculous imho. 1 Quote Link to comment Share on other sites More sharing options...
StevoD Posted September 19, 2017 Share Posted September 19, 2017 its a bit like dan. Interesting when its kept in small doses, but annoying as **** when all the time 1 2 Quote Link to comment Share on other sites More sharing options...
N4eay Posted September 19, 2017 Author Share Posted September 19, 2017 Thanks chaps, will leave well alone then. I like the crackle and pop the A45's make but I have the feeling it would be much more dramatic than them. Quote Link to comment Share on other sites More sharing options...
brillomaster Posted September 20, 2017 Share Posted September 20, 2017 to be honest I found the cobra resonated exhaust was just about perfect as it was - after a blast to get the exhaust hot I'd just sit there revving it and enjoying the crackles it made Quote Link to comment Share on other sites More sharing options...
monkeybrain1234 Posted September 20, 2017 Share Posted September 20, 2017 Overrun cackle I love. Pops and bangs i find very tacky 1 Quote Link to comment Share on other sites More sharing options...
Erni902 Posted September 22, 2017 Share Posted September 22, 2017 My decatted Nismo exhaust pops and bangs on overrun and crackles quite aggressively when rev matching on downshifts, with the occasional spit of flame, especially when its red hot. I love it but its all natural and not 'engineered' in. That being said, when it goes in for an UpRev I will be getting the engineered pops and bangs put on because I'm a child. 1 Quote Link to comment Share on other sites More sharing options...
