if you have a h/c car like your sig says I'd recommend getting some lt's, 3" catback or duals, and a tune

im just not sure about the 2 1/4 out of the headers... is that enough or is it the 2.5 thats restricting me?

Your whole exhaust is restricting you.
You need some LT (long tube) headers and 3" piping to the back (your choice of Y or X pipe).

thats exactly wat I had figured, just didnt know how bad it was restricted... cause it pulls pretty hard thru 6500 when i shift... when I have my exhaust closed up I can hear the collecter at the cat hissing cause of the restriction...

An exhaust leak is just that, a leak. It has nothing to do with your restriction.
As mentioned a better exhaust system, including a set of LTs would be a nice improvement on your H/C car compared to shorties.

no dude not a leak, i can hear a hissing noise down by where the cat is when i give the car a little gas in like 5th... there is no leak, but thanks for your input it is much appreciated! now i just have to wait for that money to start growing on trees!
