I have decided on the Mac Flowpath Cat-Back and Mac Prochamber.
Now, I don't know which one to do first since I don't have $500 laying around.
Should I just wait and do both at the same time?
Anyone know how long PartShopper will have that awesome price listed?

You can wait and do both or I would get the prochamber first then the catback. You will get more sound from prochamber than doing the catback. Alot of exhaust sound is rubbed from your stock midpipe. The catback also only gives you very minimal performance gain. The midpipe will help alot in this issue.

What kinda sound does the prochamber give out, One like an H-pipe, or X-pipe, or a sound of its own?

I did the catback first. I'm thinking I should have gone with the Prochamber first. Either way, I'm getting the Prochamber soon. I believe in this case, 5 + 5 = 15. You should see more benefit from having both, than just one or the other.

I have the same dilemma...cat back or prochamber first? Only problem here is that we have E-Check and I'm afraid it wouldn't pass seeing as there's no cat's. Would a catted H pipe really have any gains

I went with a catted x-pipe because of the E-check. So after about a year the damn check engine light comes on and I have to get MILS to shut it off. Now when emission time comes I have to swap the old stock h-pipe back in the car. This sucks balls! If I would have known this I would have gone off road in the first place.

My vote is also mid pipe first. In my case, I was quite happy with the sound and perf. boost for quite a while with just the mid pipe replaced with the stock catback. I have the older version of the Bassani catted X and never had a problem with the CE light, but have seen some of the later ones have this problem. Never seen any posts from the Magnaflow catted X's having this problem though and would recommend you looking into this type if you need cats for your emissions testing.

Definately cat back first...Work the exhaust from back to front. Why would you want to open up the middle without opening up the back? JMO...

The biggest restriction is in the middle. Why open up the mufflers when the midpipe only allows so much exhaust to past through to begin with.

I've done the O/R H and the Prochamber...kboy262 knows this personally...

The sound from the O/R H with the stock catback sounds good. The Prochamber is a little quieter but still has a good deep rumble although the pitch is just slightly higher than the H. Oh...and I would go with the mid-pipe first. You will still get a better sound and free up some HP at the same time.

You can't pass the emissions check with a catted X?
