Precisely , the TORS don't need messing about with . Not sure about the power increase as I bought the bike with TORS already installed . I have installed Ramair myself and it definitely breaths better and is smoother on the throttle , maybe a slight increase in power but the one thing i did that did make an improvement in power not masses but noticeable was to install a Tuneecu download . The one I downloaded was from Martin-Brighton-uk he is on your thread . He had his bike professionally tuned then shared it on this site , For me it works really well so no need for me to pay to have it tuned I am happy with that .
No doubt a professional tune is the best thing to do but for me I am ok .
My bike is 2014 Roadster so Martins tune fitted my bike . You would need to look for a tune on here that fitted your set up and your bike a 2008 touring , TORS and Ramair.
Depends how far you want to go as your bike will have a Cat in the crossover , this is a big restricter and others have bought the cat delete to fit in its place . That would probably would see the most gain ( TORS , Ramair Cat delete ) for the least outlay .
Of course if you want to go further it would be Viking or zard exhaust and headers with a pro tune , its all costs though and where do you stop . Supercharger , Turbo .
