Finally, some answers to the H vs ProChamber questions.

[95Vert]

Well guys, I had been running the prochamber for over 2 years now and wasn't all that happy with it. So, I borrowed a BBK h-pipe and put it on that same day. OMG, what a difference everywhere.

1. It's louder. Not annoying but rumbly and loud. Can hear it standing in front of my car, not only the back.
2. I can hear my cam lobe A LOT better.
3. Sounds more aggressive.
4. It's lighter, the box on the prochamber is open. I have no idea what the purpose of it is.
5. No more vibrations at 3k. I have no idea why my prochamber contributed to this, but it doesn't happen with the h.

6. My exhaust seems to flow a lot better. I can feel it in the gas pedal. By this I mean that the car feels lighter and not as sluggish as with the pro. It feels like it gets the air out quicker allowing more air to come in quicker and so on.
7. The scream at WOT is sick!
8. My car doesn't scrape as much.

I wouldn't recommend for anyone to get a pro over an h. I mean, I can't find a reason why. The reason I bought it was cause it was said to make more power, but it sure as hell didn't feel like it.

PS I have a prochamber for long tube headers for sale.

Hmm, interesting. I have a prochamber and I hate how mine is the 2 peice design. I'm constantly scraping it and it constantly comes loose and starts leaking. I put the stock H pipe back on it just because I like ride quality better over my car feeling like a peice of crap. Even if it means it doesn't sound as good or run as fast. I always thought of getting an H-pipe or welding the prochamber into one peice and taking the flanges off in the middle.

Do it, you won't regret it. And I have the mac flow paths as well.

No doubt it does mellow out the engine a bit - talking w/ sage2k the other day, it's almost like a 3rd muffler (the prochamber).

well what about an x pipe? pros and cons on them vs. h pipe

You will get to hear my straigh pipes with the BBK H this weekend.

You will like it, trust me.

I don't have the pros or cons of h vs x. I have a buddy with an x and I don't like it. Too raspy(metallic) for my taste.

i am running a prochamber with my mac longtubes and i really dont have any complaints. now i'm contemplating just getting a regular mac h pipe.

 

[95Vert]

don't get me wrong, the pro is a good piece but when you compare it to the h, it just doesn't match up. I forgot to mention that the drone has also minimized. The rpm drone range went from 1800-2100 down to 1100-1400 rpm. Good part about that is that I'm never in that rpm range which means that I hardly have drone.
