by the way, if you do the hogslayers be aware they will be a lot louder than TORS with the fact they have decat. The bike will not be properly tuned either because there is no standard tune for that by triumph, and the only one i know is a custom tune which i believe is not good. You will find arguments on that but i have reasons to believe that. I could be wrong, they could be wrong, but theres only one way to go where you can be 100% sure it's right.
Not to hijack but I have noticed that the Stayintune decats and uses a crossover to equalize backpressure but the Hogslayers are really straight pipe style exhaust. You can always dyno tune any bike if you have the correct interface software that allows you to adjust AF/ratios and timing. Does anyone you know of make a tuner for the TBird yet?
Will a powervision system work?
