I've decided to piece together a custom exhaust. I want something with nice deep growl but not lound and NO hightway drone. I've listened to a bunch of clips no youtube bust still can't make up my mind. I'll also be adding a ebay test pipe. I just don't want this to sound like a punch high school kid's civic

I'm assuming I'll need two mufflers and two resonators...but I'm confused as to what exactly I'm looking for. For example, when I go to summit's website there are an insane amount of magnaflow mufflers...what are all the differences?

I don't plan on going BT, just a 1+ so from what i've read I'll want 2.5->duel 2.25's.

A muffler will quite it down and a res will keep it from droaning on the HW. If you need one or 2 will depend on how you run the pipes. 2.5 will flow enough and be quiter than a 2.75-3". As long as you use a use a magnaflow or borla muffler, you will get the sound you are looking for

Would there be a benefit to running 1/2 resonators? I'm assuming 2 will be a little quieter.

Looking at mufflers on summitracing and they have a TON, I'm guessing I'll want to go with the turbo variety like this:
