Anyone done it?

Risk to damaging engine?

Basically I'm going for manifold/decat/cat back/air filter/70mm throttle and then ECU (not sure which yet).

I heard dumping a load of fuel in at run off from high RPM is good to cool the engine? Plus can result in hillarious over the top pops/bangs/flames which I enjoy due to being a massive kid

Can anyone comment on the reality of this? Have i been misled? will it be funny? Will I blow up my engine?

Aside from some oil contamination and a bunch of black soot on the back of your car, I don't think it would hurt anything (assuming you have a test pipe).

I saw a video of mine on track and it was back firing on the overrun with a 70mm testpipe and exhaust and not much else it looked wicked

My car crackles and pops on deceleration with my set up (see sig). My previous AP2 did the same with a similar set up. It's common on tuned cars with no cat.

Really? Did you hear it or did you just notice it on the video?

My H22 + S300 tuned by me + ice = loud ass backfiring from a couple bounces off the limiter in 1st gear. I had to have been shooting fire out the exhaust.
