Exhaust Popping
Hey, just a quick one like
sometimes when changing gear after quick acceleration my car pops from the exuast! it sounds wicked, just wondering if anyone knows how to do it as it seems to happen when it wants lol steve |
Yeah mines doin this since i fitted my jap style magnex.

its igniting the unburnt fuel in your exhaust.
happens more than likely when the exhaust is hot. it means you are running rich |
is that a bad thing??
|
running rich is better than lean... too much fuel means you'll make less power, get worse MPG and chuck out more pollution, but running lean can cause det which can do nasty things like melt pistons. :eek:
It's more likely to pop (and maybe even flame) if the exhaust has been de-catted.... and that's what I'm hoping when I get my decat fitted next week! :D |
Mine pops and bangs all the time, sounds :thumb:
|
i have a type r and mine pops and bangs like its gonna blow the street up sounds fantastic and i get flames all the way up the v6 spoiler really cool if your in a narrow street when everyone ducks down because it sounds like a shotgun:lol1:
|
Must admit mine was popping and banging like a b astard the other morning on the way to Oulton, partly because of Bobs map and partly down to two bottles of OB. Mine has no cats whatsoever, which, as pointed out above, does help. Throws rather a lot of flames too.
|
i tend to find i cant make it pop more by gently tapping the throttle as the revs start dropping. sounds awsome, jus like a shotgun!!

One of my mates had the same problem. Think the garage fitted a std ecu to get the right figures then changed back to his 'chipped' one. Think there was a thread on it a few weeks back. Might be in the Scotland section.

Hopefully i will have my full decat fitted soon! Got thinking what is going to be like!

There's one in the downpipe and one in the centre. The downpipe cat is the big one and so if that's been removed then there's still a chance it will fail the MOT even with the centre one still there.
