UPR X vs Mac H vs ProChamber

[sixstringthing]

Down to those three, having trouble deciding. Ive got Flowmaster Super 40's right now

UPR X: Great quality, most hp. But is this one of the few ones that sounds good with flows?? I hear some X's are pretty bad. I drove a car with an X and it made all this rasp and rattling inside, the tone was killer though. Im not sure how this one is though, I hear it has an awesome scream.

Mac H: Deep idle, more of a muscle car tone which is cool but I hear they can get really choppy at higher RPM's and drone pretty bad. true?

ProChamber: Ok this is ideally the one i want but ive heard alot of people saying its not all that loud and that really worries me. I want to get noticed w/out having to floor the hell out of it. Thats the prob with my flows, they are soooo quiet... i have to stomp on it to hear them.

so which is the best w/flows in your opinion?

I use to run the (40 series/ mac O/R h) combo on my last gt, it was nice and loud, it sounded very good actually.But i wanted to try something dif this time, so i chose magnapacks.Truthfully they have a deeper sound, i actually like these better.But as far as a pipe i was actually thinking of a upr x myslef.More power, less drone, and less crackling.

The prochamber does have a drone but then again, don't all exhuast product have some kind of drone? I have the prochamber and personally think it sounds great. I also have LT's though so thats kind of why.

As for power, there are mixed debates over which will make more power. Ive heard the prochamber is more for sound than power and that the standard x will make more power. Then again, Ive also heard the reverse of this story. I suggest doing some searches using the search feature on this site and see what you come up with. If you have questions, just ask.

You don't have to worry about the Flows being quiet with a prochamber. You will definitely hear them and it will sound like a Mustang should. I heard a mustang with BBK x with Flomasters and it sounded terrible. The regular MAC will sound good and should be a tad bit louder than the PC. My vote is for the Prochamber.

I vote for the prochamber because it has a unique sound to it. But the main reason I chose to buy it was because I have always heard that on a stock or close to stock car that the prochamber has always come out on top power wise when compared to h and x pipes. If you are looking for straight power then the prochamber or x is the way to go....but there are things to look at also, since you are running an off road pipe you are going to want a baffled or chambered muff like the flows or spintechs etc. so you will have enough back pressure to keep your low end. With that being said the x is made for a straight thru muffler and not a chambered one and gets raspy with chambered muffs. The h pipe is inferior in all aspects to me. plus everyone has them. I think you get what i'm getting at here. best of luck

Go with the upr x-pipe you wont be disappointed. The sound is mean.

I just put the UPR x on my car this last weekend and I love it, I was not sure how it would sound with my catback since not too many like dynomax. it was also real easy to install. taking the stock piece off sucked though

I've had the UPR X for almost a year. I have jba shortys and flows and it sounds kick ass you'll love it

I've had my Pro Chamber for about 2 weeks now and I just can't stay off the accelerator. The sound is just . What made me decide on the PC was a friend of mine had one matched with some 40 series Flows and it was . So I got me one and matched it to my MAC catback. Alot of people don't like MAC for rusting, poor quality..etc and I agree with some of it. But I have not had any trouble or problems with any of the MAC exhaust products so far (Thank GOD!!). I've had my catback for over a year and it still looks just as good as the day I put it on. I know because my friend and I install the Pro Chamber. I'm sure any aftermarket mid pipe will be WAY better than the factory POC power & sound wise.
