Car back-firing?

Nearly forgot to ask about this, but since putting a new back box on, no baffles witha 4" opening, the car backfires sometimes after i change gear and hit the accelerator. Any reason for this?

With no baffles & a 4" opening. I think it just released backpressure.

(muffled with the stock setup)

Re: Car back-firing?

mine does the same mate. had a funny experience passing a cyclist a few weeks ago. had to nail it in 1st to get round him on a back road. had to take 2nd just as i was alongside him. as i did that the car let out an almighty backfire which almost blew him off into the hedge
