does anybody get the flash or backfire some get when installing high flow cats or test pipes, i saw a video of a 350z that had test pipes and the injen exhaust and while sitting still revving it up, sometimes when he hit the rev limiter it would shoot a flame out of the exhaust, i was wondering if any Gs with test pipes and aftermarket exhaust was doing this.
