Sometimes when I change gear the exhaust gives out an almighty POP and scares the shit out of pedestrians!
I have a jap style back box, s/s system, decat. Is this normal??

Ive not owned an R for very long.

Also, my car is running 1.1 Bar boost. What gap should spark plugs be?

Muchos grassy arse.

Yes its quite normal normally the biggest bangs come when changing gear slowly :twisted:
Spark plug gap should be about 0.1mm smaller than standard think its 0.8mm :wink:

When i got mine it was banging off when changing gear, got a different exhaust on now as the old one was straight through with a very narrow and long silencer was probably a good exhaust but just a bit too loud :(

Check boost pipes.
Mines poping a bit at the mo due to a boost leak. It causes your car to run rich!

under 2000 rpm coasting is the only time mine pops a little, or if i really screw it for a few miles, then its every gear all the time untill it cools back down

I can play with the pops and bangs with the throttle on mine. If I just leave the throttle open a touch, whilst backing off. 2nd gear is the best from about 6k rpm. Sometimes it sounds like a gunshot. It's funny to see peoples faces when it's at it's loudest :shock:
I was out with the Honda Type-R boys last week and nearly burnt off one of their front bumpers. The guy said it was like an afterburner :twisted: :lol:

Flame on.....

Strange...I have a 5 inch full Mongoose system and mine only pops very occasionally. Is this a good or bad thing? :?
