If it's spitting out flames then there is unburnt fuel coming through. Won't be a problem with your exhaust being welded.

Possibly. He would need it looking at by a garage to determine the cause.

Sounds like major overfuelling, especially to shoot 2 foot flames, you will need a hell of a lot of whack to do that.

I cant see how changing the backbox would cause it to do it. It might be understandable if you fitted a ful system. The cat would of been destroyed by now, and id never seen a standard car flame like you said, especially with a cat.

I sorry but it all sounds like a load of poo to me, get a video up to try and explain it.

thats why it shoots flames then, its overfueling slightly.

and with no cat the flames wont have a restriction.

mmm only the backbox and its doing that :S , i have had to have a full de cat and no silencers only the backbox as the silencer on mine for it to backfire :)


I would take it to a garage and let them have alook at it or try and read up on it somewere? as you might be paying for labour and them not doing anything to it :)

I only said that mate because you said that you changed the backbox thats it.

You didnt mention it doesnt have a cat or a mass air flow sensor, the missing parts which is causing it to flame :rolleyes: :rolleyes:

not wanting to appear as being a killjoy but...be careful if u cant control it flaming and the police see u....they'll take the car off u there and then, and impound it. or worse they'll scrap it. they dont take too kindly to flames etc.
