Janspeed Exhaust Producing Flames...



I was out with some friends last night, and one of them informed me that my exhaust is producing a fair few flames out of the back, I have recently decatted it and it has no silencer, so it's basically just a backbox.

I knew it popped/spat on cold, but I didn't know it was flaming. Is this normal, or is the decat doing something it shouldn't?!

Probably just fuel igniting in the pipe mate.
 
Is that normal though?

Relitively normal on decatted vehicles. The popping you get is the igniting of the fuel you can vocally hear, before you decatted it the cat would have reduced this. Now you've decatted the system it is more free flowing.

If you've noticed no adverse running issues then I wouldn't worry.

Mine tends to pop when water is almost up to temp, and changing gear up to 4/5th at 40-50mph, and applying WOT.
Also if blipping a downchange after a long cruising period.
RS2 intake btw.
 
Mine pops/spits if it's stone cold and I take the revs up to 3-3.5k in say 3rd and let the revs wind down. It goes ape then!

Only other time is when I blip the throttle on downshifts, but only if it's quite high in the rev range.

Mine pops and bangs like mad when cold even at very low revs.. And still doesn't when it's warm but not as much.
