Help s2000 family! I'm new here and also just got an s2k. I recently purchased an HKS HI POWER SPEC L exhaust for it and I was expecting it to be a little bit louder its sounds really good at high rpms but lacking in idle and start up I was looking into buying a test pipe for it... although i dont know if it will make a noticeable difference. I'm looking for a deep aggressive sound with NO rasp... Any advice out there? Price is not important here! THANKS.

 

If you ask me, the best exhausts are quiet when you want them to be and loud when you want them to be... quieter at start and idle and highway cruise yet loud when you go WOT. I would also rather an exhaust more on the quiet side than on the loud side.
A high flow cat may give you a bit more sound though if you are looking for that.
