You can experiment with different cans and db killing baffles all day long. Sure you could buy a power commander and squeeze out a few more ponies with an exhaust of your choosing. But my opinion is if you want "gains" you get a Fireblade. I'm playing around with VFR exhaust cause I like the sound. Now if your Power commander reasons are for smoother fueling and throttle feel, ok I'm cool with that but. "iM geTting mOrE POweR" 🤣 buy a CBR. To be fair, I think re-tuning post-exhaust change is to keep the engine running well (e.g., not too lean) for longevity purposes - performance gain reasons excluded. Quote

It's fine. I've had all sorts of random cans on 5th gens of the years. Stock, mild steel collector-link pipe failure on ride so trek home 100 miles was open header, two bros, Yoshimura, various Delkevic. No mapping for any. Here's Delkevic's eBay listing for their 8" shorty with link pipe for 2014 VFR800F Quote
