A couple questions. . .Ok, what is the difference between a "cat-back" system and a muffler? Does a muffler do anything? Does a whole exaust make that much of a difference over just an exaust? I was just curious, because you can pick up a muffler anywhere for $100, however, I can't find an exaust for less than like $370. So, if an entire exaust is better than just a muffler, where can I get a reasonably inexpensive exaust for a P5?

In other news, I pick up my P5 tonight. . .I saw it at the dealer today, it still has the white plastic all over it. I will post some pics of it tonight as soon as I get home and are done driving it for a little bit. Latas.

welcome, and congrats on your new P5

cat-back is basically a full replacement of exhaust piping AFTER the stock catalytic converter (hence the name CAT-BACK). A muffler is just a muffler (duh )

do a search on 'cat-back exhaust' or just 'exhaust' if you haven't done so already. This topic has been VERY VERY thoroughly discussed in the forum

also check out the FAQ, it is very useful because it's nicely organized and laid out on all the choices available for the Protege

Well I had a muffler only at first and it made no change at all.
Just got my new custom cat-back and I can tell a little difference in performance. 0-60 seemed about the same, but when I reached around 40mph or high RPM that where I felt the difference. My 40-60mph accel. seemed to increase some. Its not a huge difference, but its enough to where you can tell something has changed which is good enough.
