prety much. is there any way to find out what kind of flowmaster is on my car it was on there when i bought it

primetime5.0

I think there all just stamped "FLOWMASTER" I dont think they list a part number on there

LX 90

yea all thats on there is patent numbers

actually if you want to get technical h-pipe sounds better, x is more performance, and the chambered h-pipe is not much better then the reg h-pipe it just gives it that flowmaster sound because of the chambers, an x will outdo an h anyday, dyno #'s ask anybody that dynos stangs. x = owns h. h just sounds better IMO.

x owns h by a few ponies its a trade off whichever sounds better

yea and the x is only like 2-4 more hp then the h. i like the deeper sound but ive recently started taking a liking to the x-pipes, plus the x is cheaper then h, or the h and x i want the x is cheaper. + im not a big fan of mac.

yea they're all basically the same... i bet if you installed one and then drove then installed the other you wouldn't tell a single difference... only in sound

read this

http://www.bbkperformance.com/products/exhaust.shtml

this shows acording to BBK that an h-pipe gives more ponies then an x-pipe

LX 90

either way its not a deal its just a difference of like 5 hp so it all up to personal preference in the long run

Ecstasy

i dont see anything in there that says that and i dont care what bbk says, im going by what i seen on a dyno from switching a friends car from an h to an x.

not to mention if you read closely under the h, it says 15-20 hp, if you read under the x, it says rear wheel , you cant go by that, i bet their h-pipes are more expensive then x.
