go to installs, theres even a way on there to trick your o2 sensor so it doesent come on.

Waste of money.

so is a 250$ intake that gives you 5 hp... its all about what you want to do to your whip.

Cars built in the mid ninetys and later COME with what would essentially amount to a high flow cat. They don't come with anything resembling an AEM V2 intake.

ShavedH22CL

well dick sorry but my hiflow cat is a 2.5in pipe Hollow straight through no baffles like the stock cat and its not even close to what my stock cat looks like inside

LLWesMan

Take your namecalling back to your kindergarten class please. Grow up. You made a thread, people posted their opinions/responses. Don't get your panties in a bunch because we don't all love you.

its way different from stock.. besides the baffles..i put mine on and my car went from a constant low rumble to what sounds like an srt-4 girgle. i took it back off, but only cause it was 1.5" too short and pulled my tips really close to the bumper. now i got it streatched, and i do plan on puttin it back on as soon as i make the o2 sensor mod.

i tried to do it the cheap way and hollow out mine and sounds like shit...i regret doing it.

so i put it on today and i do have pics of the old and new inside and out and size and it sounds amazing. Next week is Energy Suspension Hyperflex Kit and then after that the H22 goes in hehe with A Greddy Header VAFC and Skunk2 intake manifold, huum what a nice $1000 bonus from work and its already spent.

And the hi flow cat has no O2 Housing o well haha

IMO a "high flow cat" (which is really a test pipe with the honey comb looking shit inside to muffle a little bit) is a dumb thing to add. itll make your car louder(which is sometimes needed but to a point), more annoying, and VERY raspy and ricey sounding at high rpms. all three of the people i know who have test pipes, the obx thing or an ebay one or even hollowed out the cat, thay have all ended up sounding pretty shitty and they all regret the decision. so if you were to go get an actual high flow cat, catco makes them.

I have a Catco High Flow cat and i really like it. it doesnt make my car sound ricey at all. as a matter of fact, coupled wit my magnaflow and 2.25in piping it sounds really nice. and it has an inlet for the O2 sensor (which i have to change cuz mine is SHOT) so u dont have to trick it out. it was only like 110 too, good buy in my opinion

wilp99

i think it was one of the ones from ebay.. straight piece of pipe with fittings on the ends and a bung for a o2 sensor.. i bought it from cocoa

h2o-pr00f

i want my shiz to sound like that.. when you get it done u gotta make a short vid i wanna hear teh rumble

bkmc24

by this post i thought you were putting the shitty oBX one on not catco??

The ricey sound you get from "straight pipes" also comes from having shitty exhaust/engine type/pipe size.....and a few lil factors. Try saying the cars at the tracks sound "ricey". Those things are sick, and nothing beats the sound of a back fire. My car is straight piped, cant see myself without it. As well as all my friend's. The only car that sounded close to ricey straight piped, was my friend's EM2, but then again he has a crappy muffler.

bkmc24

haha okay ill agree with you, but all of the 4 cyl and v6 ive heard with them aound like shit! lol but ya know, i love a V8 with strait pipes so yeah

iTrader: (2)

oh man....those thing crackle like no other. I love v8's straight piped. But I wasn't trying to convince anyone into agreeing with me, just giving my 2cents in it. But, go to the Ontario street races, and EVERYTHING there sounds ricey. Like you said, it just depends on the cars your around.

h2o-pr00f

chris what kinda straight pipe hi flow cat do u got goin?

Cocoa

iTrader: (2)

I took my cat out and beat the shit out of it on the inside.....(hollowed it out)

bkmc24

haha i kind of have that done, i cut out the shit by the header. idk what it is tho, its got kind of a smaller hole in it, just to give it some sound and little more flow, but trying to keep it un raspy

ghost_masterCL

so do "high flow cats" not have naything in them to change exhaust gases, or are htey just a more efficent way of doing it?

If I were to put one in, would I not pass emiisions?

bkmc24

they are basically atest pipe, the obx one and ebay ones are strait through and have the honey comb looking stuff thats in after market mufflers to quiet it a bit, but catco after markets i think are diff, dunno tho.

emiisions, if you buy ebay or obx, doubt it, but catco, not sure aagain sry

ShavedH22CL

You would not pass emissions because in a real cat there are these little balls that soak up a gas that ur Motor makes(i forget the name of it) in a Hi-Flow cat those little balls are not there and that is the easiest way to put it. it reaks haha but it sounds good and l enjoy it alot you can tell that it isnt as restricted anymore i have pics of the old vs. new and installing if you would like them.

wilp99

balls...? mo man theres no balls in there.. theres a material called catalyst almost made like ceramic.. and the gas is called emissions. (emmission vehicles)

ghost_masterCL

ok, I just wastn;s ure if hte catalyst was lining the walls or something instead of being a huge chunk in there.

You will pass emmissions with high flow cats. Practically they are made with less catalyst making them "high flow", but nevertheless, does in fact function like a normal cat. They will say they are legal high flow cats on the box, or say that they'll pass emmissions, blah blah blah.

Test pipes, race pipes and straight pipes will not pass because it is hollow, thus meaning there in nothing in it! There is no catalyst in the pipe, it's just goes straight through like normal piping.

Hope that helps clear some things.
