So it’s +15 rwhp and +8 lbs rwtq from headers and midpipe over testpipes. The CNT rear exhaust was used with the testpipes and new system.
I’d guess a catless x-pipe would be worth 10 rwhp over test pipes and ~5 lbs rwtq.
Based on that, I’d say the headers and “larger” diameter piping midpipe are worth ~5-10 rwhp and maybe ~5 lbs rwtq over stock headers and the typical catless x-pipe.
Still worthwhile for someone chasing every gain or someone who is thinking about buying testpipes or an x-pipe. This outgains testpipes or a standard x-pipe for the price of a standard x-pipe.
