Honestly, I don't feel any difference in HP after doing the quad exhaust. Regarding the air filter, it won't help with anything unless you get a tune to match your mods.

My car is a 545 so the diameter is 2.25", on the 550 I think it's 2.50".

make sure you keep the stock cats and stock front resonators if you don't want the exhaust too loud.

Oh okay about the dinan. I don't have the porche tips I saw them in a website and thought it would be different. Did you go to a indy shop? Or a muffler shop? What was your ballpark cost

I forgot the exact price as I ordered them a while back. The last time I contacted them for another set, they quoted me 350 shipped for a pair.
Unless your indy shop is capable of custom muffler work, take it to a real muffler shop. I paid about 250 for the install.
