exhaust question

who knows if its true or not but iv always bin told that flowmaster and other mufflers with chambers work best with a h-pipe....anyway all the after market h or x pipes iv seen came with a pipe to hook the air tube to even my off road h pipe had this. and they all have bungs for the o2 sencers

Thanks Wayne, the pictures didn't show or tell if they could hook back up. Did yours improve performance or sound better? It was just such a pain to get the stock unit with the cats and whatever the other things are that are just below the o2 sensors removed from the exhaust manifold. Had a horrible time getting to the lower nut on the passenger side.

From my experience, anytime you get rid of cats, or pretty much any stock exhaust component, and replace it with aftermarket it is going to be a great sound improvement and in some cases a visible power increase.

a off road h-pipe is way easyer to install and remove cuz there arnt any cats in your way

I am looking at replacing my exhaust system too. Only thing is i live in ca. so i have to have the cats to run street but on of the big thing about going aftermarket H pipes with cats is that in stead of 4 cats on the stock it has 2 high flow cats. headers will also make a difference cause the stock headers i tiny. if you are going to go super or turbo it go for 1 5/8 if not go for 1 1/2.

i dont think removing the cats will have that significant of a performance gain. for the price of an X or H pipe with cats, you might as well stick with the stock set up. and since you already have the flows, it probably already sounds pretty good. is this your car or your wifes, because the new H pipe will definately be louder , and with flowmasters, it may just get annoying depending on your sound likings. also if it is your wifes car, unless she is a real hardcore gear head, dont go with the offroad pipe, because it is almost intolerable to be around the car while it is idling because the rich smell. (dont think she will like that too much.)
