i think u would gain a few hp to the wheels, how much idk, it all depens what u have done to ur car thats a good investment though if ur planing to build it. Just be careful with bbk all the stuff i bought from them wernt the best quality so i had to machine it my self.

well right now im pretty stock .. just a cold air intake... im gonna be putting some BBK headers 1 5/8" unequal + BBK H pipe or X pipe.. after that.. MSD distributor spark plug wire from MSD i guess or ACCEL idk yet... after that... no clue tho

i see thats cool, well from the results that i seen u do get a few hps to the wheels, when a product advertises there hp gain something els is done to the car to gain that much hps out of it, so jsut give them a call and see what they have done to there test mule to got that horse power they claimed an intake helps out if u get the right one, all that sounds good jsut get cats with that, cause ul loose back pressure and some of ur bottom end

could i just buy some Magnaflow High Flow cats and weld them in the BBKH pipes or X pipesor do we have sensors in ours cats..?

thanks

well if u ask me theres no such thing as high flow cats, if there is its a verry minumal differnce in flow. i wouldnt do that i would jsut get the whole xpipe or hpip with the cats, i think that would be better theres no need to not get cats unless ur planing to make a lot of hp or boost ur car then getting rid of them would make sense, yes u got o2 sensors that go there.

75mm is way to big, You will lose horse if anything. I would go 65mm for your car and port out your upper intake throttle opening. If you plan on a h/c/i swap down the road go for a 70mm. That won't hurt you too much for now. Bigger is not always better.

Your car would also run like **** with the 75

would the car need a tune after the 65mm trottle body is installed?
