Which do you guys think I should get? How much Hp would I lose by getting the one with cats?

shame no-one replyed, I got the one w/out cats, and it was one of the best mods I have done. Just keep the stock one for testing time.. Well worth it for you.

Yes, get the w/out cats. If you have stock mufflers still. It is not that loud. But a lot nicer sound

I plan on going with a full MAC exhaust. MAC longtube headers, prochamber and axleback. I was going to get theprochamber with cats for emissions purposes. Anyone have any thoughts on that?

If you keep the cats. It might not be to loud. But usually, when you do both mid pipe and mufflers. it can be obnoxisoully loud

I don't want to be obnoxiously loud, but I want to be pretty loud. I guess I'll go with the cats so I can pass emissions and still be loud.

Timmay!!!

The O/Rprochambers I've heard on SN-95s 2V and 4Vs seem to be a little quieter than O/R H and X-pipe but deeper than both. Great happymedium.

I have the mac long tubes with a catted prochamber and roush off road mufflers and it sounds great to me. I will try to get a sound clip for you. I also heard that mac stopped making there catted prochamber.

I have the Mac catted prochamber and Mac axlebacks. It is plenty loud, and gets complimentswherever I go.

If you ever plan on getting LT's, I would be very sure you are okay with a VERY loud car if you go with the O/R Prochamber.

What you could consider is going with the catted for starters, and if you change your mind just call Mac and order the O/R legs.

i would go with cats. i think it would be too loud without them
