Most people don't need a pipe, they want one and there is nothing wrong with that. You wont ride much faster unless you commit to a few more upgrades. I know riders who prefer stock pipes because the noise isnt a distraction but aesthetics are another thing and I think the Akra's are styled well, you wont find an ugly can in their range. The prices are ridiculous for a bit of welded tube but then again plenty of people think nothing of blowing 500 bucks on a Friday night out so each to their own. I'll also stand by my previous comment that an expensive pipe doesn't add much value to a bike, especially as it gets older, but for sure discerning buyers would go for 8k Akra over stock all things being equal.
The short version of the above is, if you have the $$ get the Akras but dont expect to get your money back, these are toys not investments
