h pipe to an x pipe

[udlooz]

went from a h pipe with no cats to a x pipe with two high flow cats. how much power did i lose if any at all.the car feels the same but the noise level is half.

You probably lost a little, maybe 5-10hp, but i wouldnt worry about it. The noise reduction is from the cats, not the X. If anything you might have lost more torque due to the X pipe than anything.

i thought that an h pipe makes more hp up top but less torque down low, and the x pipe was vise versa; more torque down low with a few less ponnies up top???

nah, vice versa, x makes more HP up high but loses Tq, i want to get a Prochamber myself and have the best of both worlds, maybe next month.

Pro Chambers are nice, this is my first one and i've had plenty of Hs and Xs, i'd have to say i like the PC better than both. Funny thing though, is if you get a cross section picture/diagram of a PC, it's actually very similar to an X, only MUCH more flow between the entire area. Definately gives a totally different sound than either H or X.

MAC has a great sounding exhaust, some love'em some hate'em, but when you pair up their entire setup like i have in my sig, it flat out screams at WOT, and has a really unique "glub" to the idle. VERY little drone also, but that's mostly because i run above 2k rpm with my 4.10s.

Hey udlooz,what kind of x-pipe did you get?
