+1 for Borla ATAK! Definitely a head turner, and yet drone free. I love mine.
It may not be the cheaper option, but its definitely worth it and the smarter purchase in the long run thanks to its brilliant modular design.
The quality of Borla's exhausts seem like they will probably outlast the rest of your car anyway... but the NPP valves are moving parts, and moving parts tend to fail at a point eventually, regardless of the brand and manufacturer... and thats one way where the Borla NPP option is the smarter one, as with their axlebacks, if a valve ever gives you issues, you can just swap out the outer exhaust tip which contains the valve, instead of swapping out the entire axleback or doing any cutting and welding. easy.

Just my two cents.
