Exhaust Popping

[DVS R34]

I have a non-turbo R34 and the exhaust keeps popping. a mechinic told me that it was the high tension leads and that i will need new ones? another mate said that there aren't any leads there!

so i was wondering if there are any or not and how do i fix this popping noise?

poping noise would be running rich, a tune up would be best.

No high tension leads on RB's so he probably doesnt know them.

My exhaust pops all the time on my R33 N/A.

It has a 4" catback 5" tip. IF your car does it while slowing doing its the depressurisation in the exhaust (apparently). I wouldnt be concerned about it, unless it does it while ur driving along normally.

You're running a 4" exhaust on an N/A 2.5L! Jeezus christ.

When slowing down, you will find that the cylinder isn't getting complete combustion (Because of pressures between inlet manifold/cylinder/exhaust and basically, since the revs are up, but no huge volume of air turn over, the exhaust sucks out alot harder, and it also stops alot of the combustion from taking place inside the engine, and draws it out into the exhaust where it "pops"

Normally reffered to as cackling.

But if it pops like back firing, time for a tune (Although mine creates some MASSIVE back fires when using second gear to hold speed down steep hills (60km/h speed limit) and just tapping the throttle on and off slightly creates even bigger ones... Good way to get people off your ass...

get a smaller exhaust!! No need for a 4inch on an NA.

Same thing to my mates gts. A lot of popping on that huge exhaust..Swapped it for a little smaller one.. Much better
