Folks,
Hope everyone is keeping well.
Anyone have any experience with Blow Performance Exhaust?

 

I was looking at them for a few weeks because I really liked their kutbak exhaust with the copper heat shields. I came to the conclusion that the numbers they give for performance (HP and TQ) are fraudulent because they don't have any real dyno charts on their website or youtube channel. They claim to give gains greater than a 2into1, yet they don't even have a crossover port. I emailed their support several times for some actual dyno charts and was met with mild hostility. The fact of the matter is that the M8 motor does not perform well with a short 2into2 exhaust system.
