Default I need advice about my exhaust ...

Ok so at first I had Borla Headers - Stock Cat Section - 2.5" catback.

Yesterday; Borlas - 2.5" ALL the way back. Its way to ****ing loud... like rediculous. It sounds mean but way to loud. So I dont know whether I should try to find a cat, or put the stock section back on... anybody have a similer situation and fix it?

i was thinking of possibly buying an STI muffler to look stock, but it will inhibit flow a lot more than a resonator.

What kind of muffler did you have on it?

No muffler = real f-ing loud... you can put a resonator on it if you want, but it will still be real f-ing loud...

Resonators do cut A LOT of noise. I helped a friend install a turbo back exhaust this past weekend. We drove it with the resonator and without. Huge difference between the two. Without the resonator, we could not hear eachother in the car without shouting. With it in, it was slightly noisier than stock. It was definitely restrictive though; the difference in power was noticeable.

I think what im going to do is weld on an STI muffler. I like the stock look... and it may restrict a lot more, but it wont be as bad as having the cats.

A straight thru perforated core resonator shouldn't restrict a thing.

Are you talking about the plug that goes in the tip? If so.. that's not a resonator.

Perhaps. What I am talking about looks like a slightly conical shaped pipe that fits into the short pipe sticking out of the muffler. My apologies, if that is not a resonator. That's what I was told it was. If not a resonator, what is it called?

As Piker posted, BPM calls it a "silencer." We'll know for sure in a few weeks exactly how much HP loss it causes when I go to the dyno. I'd guess about 1/2 - 1/3 of the overall gain from going to a 3" TBE.
