My cat. need replacement, soo Which one would be better a hi-flow cat or a test pipe? And which hi-flow cat is excellent?

 

Depends on budget and sound.

louder? = Test Pipe
Cheaper? = Test Pipe
Less Environmentally sounds = Test Pipe.

I say high flow cat. Heard decent thigns about stillen's high flow cat (~$250)

 

Im looking for something to give me power, sound nice and not ricey.

 

high flow; test pipe sounds raspy.

 

Custom Enterprise has a high flow cat for $150..doubt its stainless, but its an option. You might even get better performance with it. A test pipe would be way too loud under the cabin, anyways.

 

Any cat > test pipe. The Cattman cat is pricey but very nice.

 

... like all cattman products.

Wish I could afford their products.

 

You will get more power from a Test pipe but dont plan on passing smog

 

i had a high flow cat than i switched to a test pipe. it is only raspy when the car first starts up it goes away within minutes.

 

Gains will be minimal .... if any.

 

if you had a turbo it might be worth the extra 2-3 p.s.i. but otherwise, its just gay for a NA car.

 

My cat also needs replacement. Im going with a hi-flow for 2 reasons over the test pipe. 1 I dont want to be putting in a cat each time i have to do emmissions, as the gains from hi-flow vs test pipe are, as nmexmax said, "minimal .... if any". And 2 im getting a hi-flow cat in exchange for an axe, which i found for free, and stock orange corners. (Long story on that) Anyways, if i was u id go with a hi-flow cat as well.

 

Dont go with a test pipe, they sound like **** and do nothing. Get a hi-flo from warpspeed for $100, I have one and have no problems. The sound of the exhaust didnt really change. The only reason I got it was because my cat was bad, infact that is the only reason you should get one, they give no gains.

 

lol an axe.
and i thought the gain of the hiflow cat was minimal. it sounds like your saying the DIFFERENCE between the test pipe and the hiflow cat are minimal.

 

well its kinda hard to ask you since u had a bad cat, but so do I. Did you notice any gains, and is the sound clean.

 

I currently have the CM hi-flo, and it doesnt sound too bad.

 

can emissions be passed w/a high flow or test pipe???

 

Not with a test pipe

 

Didnt really see anyt gains. It sounds slightly different, but pretty much the same as the stock one.

You can not pass emissions with test pipe, but you cna pass with a hi-flow.

 

I say OEM cat. Unless your cat really need to be replace. I have a test pipe right now because my stock cat was clogged up, had a opening size of a nickel. What do I think? I don't like it. Don't replace your cat unless you have to. I'm looking for either OEM cat right now, might just go ahead and go with a brand new OEM cat. Anyone know if muffler shops carry OEM type cats?

 

i have a test pipe. love that sound. 20$ on ebay

 

You finally put the clears on

 

I think his car was one of the few that actually looked good with the ambers on.


Cumalot: the difference between OEM and hi-flow is negligible. Do you have any idea how much an OEM cat costs form the dealer? Its a few hundred bucks. If you need a new cat, a hi-flow is the best way to go. Its cheapper than OEM, it barely changes the sound if at all, it will still pass emissions, and it might add some slight HP.

 

my test pipe sounds exactly how i want it to sound

not very loud while just cruising
LOUD as SH*T when WOT

F*** a test pipe tho, get a cat

 

But going by what I've read on here, it wont last as long ....

 

Yea it did look pretty good, I'm just a fan of the clears over amber any day. I think it looks better.

 

Both sentences hold true no matter how u look at it. The differnce from OEM to hi-flow is minimal as well as hi-flow to test pipe. Main reason to get a hi-flow is because its cheaper then the OEM, and yet still has the same effect for emmissions as the OEM cat, where as the test pipe will fail.

 

well put.

 

You know you want to get it. . . . . . . . . .

i have the CM resonated test pipe. i got HUGE pop and rasps but it was b/c i didn't make everything flushed. after i spent about 2hrs carefully reinstalling it, it went away. sounds fine

 

You've been on the .org for 3 and 3 months years and you are actually asking questions about "growling intakes" and high flow cats vs. testpipes?

 

I may have been on this site for a long time but dont invest a lot of my time on the site. It doesn't hurt to ask fellow org member who have diff things. I of coarse don't have a lot of money to say "Hey I tested every intake/exhaust setup". This is why we have forums to ask.

 

I had a random tech. Hi-flow cat on. My car is extremely quite, Im looking for maybe a deeper tone. Prob ill go with a CM hi-flow cat.

 

That's why you have cat problems/codes.

 

I have a CATCO CAT

 

just get a carsound cat...i passed smog in my accord with it

 

not worth the money for a test pipe unless youre going FI or you just dont want to pass smog. if youre thinking about a hi-flow cat, get one only to replace a bad stock cat. other than that its a waste of money.

 

With my random tech, when I went for inspection 3 months ago with a greedy exhaust/ stillen y-pipe I passed emissions. Nox was a bit high but the kid who did it ran it in 1st gear.

 

In the early .org days tehy were know to fail prematurely.

 

Thats good to know, It gave me a few problems here and there. I Decided to get the custommaxima.com One with the installation kit.
