Exhaust....how to upgrade?
Was looking at possibly getting a new catback, but funds are a little limited after having to replace coil/battery/misc wiring/distr. etc etc. Was wondering.....will i really notice a difference performance/sound going from the stock 2.5 crush bend (with performance muffler) to a 3 inch or 2.5 inch mandrel bend cat back? If the difference isnt much noticeable between the 2 choices, i may just stick with stock piping and get a new muffler. Also, is the dynomax catback any good? Makes me sad I can only find it in 2.5 seeing as how my slp y pipe is 3 inch.....

whatever you go with, get a 3" kit. Dont bother with anything smaller.

Yes you'll notice a difference going from a 2.5" cat-back to a 3" cat-back. Dont get anything smaller than 3", as said above.
But dont make yourself broke getting one. Food and rent are more important.
