Catted v Uncatted
 

Just a quick question before I make up my mind and dish out some green, does the off-road H pipe from MAC sound THAT much louder than the catted? Thanks

a catted pipe always more quiet then a non-catted. for my Gt's case it is WAY louder without cats...dunno with your V6...but yes it will be louder with no cats.

It will be louder without cats, yes, but some people say that taking the cats off of a V6 makes it sound raspy at higher RPMs.

that raspy threat is all i need to hear to steer me away from off-road, but i just dont want it to be quiet with cats, but this would be the h pipe and catback, not just a y replacement, so. im lookin for as beefy as my six can be and sound like a mustang, thats it.

maybe find High flow cats for it. louder than stock cats but quieter than no cats. I am unaware of the options for a 6cyl. car though.

I like catted pipes because they smooth out the sound.A catted X pipe is alot louder than the stock H pipe.

well the h-pipe would be louder than the stock y-pipe for sixers. Looks like im goin catted! I just wanna spend the money and finally experience dual exhaust.
