Fire popping exhaust
« on: 18 August 2012, 11:03 »
Since fitting my de-cat i have(other people behind) have told me that when i change gear(5000rpm +)
the exhaust spits out a flame. :cool:
What damage will this cause,if any?

I have a straight through exhaust with de-cat,pipercross panel air filter and have no engine mods.
I will try get a pic sorted of the popping flame.
It has been running like this for more than 8 months now.I have had no running problems apart from the maf sensor,which i sprayed with some sort of electric cleaner and has been fine since.
Oh and she does run a little rich

Over fuelling, damage will be done to valves and rings etc and not your exhaust.
You will be down on power and probably fail an emissions test
Can wreck a cat but this is not a problem for you :grin:

I have this going on at the moment, sounds like a V1 when engine breaking into a corner :grin:
kind of gone too far with a dremmel :lipsrsealed:

Unless its massively overfuelling it's fine. All engines would spit flames, the thing that stops it is the cat and any silencers in the exhaust, and as you have none then you have flames. If it is overfuelling a lot with strong fuel smells and massive flames then it can wash out the bored and cause damage but that's in extreme cases.

If yours has no car or any silencers how bloody loud is it?
I removed the middle suitcase box on my black golf just leaving the cat as backbox and it was so boomy inside the car that it made my eyes shake and my vision go blury when driving. I had to change it back after half hour of doing it.

How can you see your exhaust tailpipe from the drivers seat?
