Difference between Mac Prochamber and regular H pipe?

But Seraphitia, you being in CA, can u change mid pipe???

Chicane Sport Tuning is willing to change my midpipe. Everyone I've talked to there says it passes the sniffer portion of the test but not the visual unless "the original emissions system was broken" [gets a hammer] Since Ford does not produce anymore 99-04 exhaust systems, the man at Chicane told me that it's legal to get an aftermarket solution since the original manufacturer stopped production.

He told me what it doesn't like to see 2005+ Mustangs change their midpipes since it's fully working and Ford still produces OEM parts.

well I'll throw my 2 cents in here having had stock, prochamber, mac h, and now an xpipe.
Stock we all know what it sounds like and how it pulls.
Prochamber - lil throaty nice sound not real loud. strong from idle-5500 nice and smooth. WILL not clear a DS loop and allow tech to see it. UGHHH
Mac OR hpipe - sound makes me drool however mine would never stay sealed and exhaust leak free for more than a few days at a time. UGHHH pulled from 2k-5900 was nice felt a lil less torquey down low had to use the gears more.
Xpipe - sound is well an xpipe raspy kinda nascarish to me. kinda weird on the rpm badn though. Pulls good from idle to 2k or so then goes kinda flat till over 4k then rips to redline. So I've found I either have to use the shifter more to either get down into the low rpms for city driving or let her rip to pass on the interstates. very weird IMO. But it is leak free, and clears DS loop.

what's a "DS loop?"

Driveshaft Loop. It protects against the drive shaft snapping and launching your car in the air.

I have the o/r prochamber with magna packs and I even got pulled over once for it. The cop just wanted to know what my setup is. I love South Dakota where you can tell a cop that you stripped the cats off the car and he thinks it's cool. My combo is LOUD!!

I live in south dakota and i got pulled over for my exhaust on my pickup (not that loud, well wasnt at the time it is a little louder now ) I was told to fix it properly as soon as i got the money. Well i had the money then and i used it eventually.... to make it louder
