I have a 2005 STR and so far everything is bone-stock. The stock exhaust note sounds good at WOT but other than that its too civilized for my liking. I have been researching performance exhaust systems for about a week and have come to the conclusion that it will be cheaper to buy each part separately from a supplier instead of the entire exhaust system (aka catback from Eurotoys). That being said...does anyone know the specs for STR exhaust system components (length, diameter, etc.). For now I am just looking to modify everything before the catalytic converter but it its affordable possibly all the way back from the manifold.

Also, I know I could just add the Milltek rear mufflers to replace the stock ones but I am not sure how much that would make a difference. I am a newbie at this so I am open to any and all suggestions. Thanks for the help in advance!
