Hey guys. I’d like to have this awesome exhaust note for my 911 that is track only. I have a 3.6 with stock heat exchangers and a custom 2 into 1 open exhaust that sounds nothing like this.

Would this be the Stinger exhaust withOUT silencers from GT Racing Products? http://www.gt-racing.com/porsche-911-stinger-exhaust-pipe-no-silencer-part-911-stinger-ii/

Or the one from Tarett? https://www.vividracing.com/tarett-engineering-stinger-exhaust-system-finish-porsche-911-6589-p-151379360.html

Which one will generally give me a HP gain (or loss) and how do these exhaust systems get to such a high pitched note anyway?
