vibrant is 3" if ur keeping ur mods that u ahve now and not doing much more, go with 2.5, itll sound better.

i went witht the vibrant because my goal is 300 hp at least. the rule of thumb is every 1" = 100 hp

mine is loud when ur on it which i hate and might consider another resonator or something to quiet it. but normal driving its badass. but i also have a leak now whicih i need a new gasket blah! lol

 

vibrants downpipe is 2.5 I looked on there site and quite a few others.. they have to exhausts, one is 3 inch and the other is 2.5 i believe..

 

i got their header dp combo, its a 3" with a 2.5 outlet

 

oo ok.. i was talking about the combo, i thought it was 2.5 all through?? good to know Thanks buddy

 

no prob, i had to research for the gasket, learned about it lol

 

only thing that leans me towards zzp is the whole for the wideband, or does vibrants combo have it.. there site doesnt say??

 

you would have to go to a shop and have them weld it on separtly.. most shops will do it but it will cost you lol

 

how much do you think it would cost?? under 100 bucks??

 

most shops only charge like 20-30 dollars i believe, but with some u have to remove the header which then u have to had install which would bring it up to 75-100...

vibrant does not have it, i need one though lol

 

basically now its the flip of a coin, cause i wanted the zzp stainless dp, magnaflow cat, ceramic coated header and wideband port.. comes out to 610 or so.. which isnt bad..

 

the vibrant is 600 by itself i believe, thats what i paid

 

lol should have jumped on the discount train lol

 

i aint got money at the moment.. not for a few months or so, so it doesnt matter to me either way.. i plan to get the 2.5 magnaflow catback first (ss/sc version) then will do the header and dp.. i love the vibrant look, pure sex ::mouth waters::

 

i prefer the ZZP due to the multitude of options it has. It also has different sizes for the primaries for 2.2/2.4 and 2.0 applications. Im unsure as to what the vibrant's primaries are however. i couldnt be happier with my ZZP. also, to add a bung to the ZZP its only $10....it comes with one on the header collector point and one on the DP, but if you have the sensor for the header ( i believe 2.0's and SAI fitted 2.2s have it....my 2.2 SAI has it), they can include an additional bung for $10. Anyway, my ZZP performs wonderfully and sounds amazing! nice deep rich tone. ive also got the GMPP sport exhaust fyi

 

blah they will respond to your email but try to get something warranantied thats defective.

 

I'm very pleased with my Vibrant header/downtube. I didn't have any install problems and it didn't and still hasnt thrown any codes after about 1000 miles. Not bashing ZZP in anyway, but you can't go wrong with the Vibrant.

 

Thanks for all the responses and opinions! I am still undecided on which system I will get, I was leaning towards vibrant but I am not sure that I want a 3" DP on my car.

Does anyone here have the ZZP setup with ceramic coating? If so, do you have pics and is it holding up well?

 

Just so you know sir all zzp downpipes are 3 inches all they do is weld a 2.5 flange on so it could bolt up. zzp does not make 2.5 inch downpipes

 

somethings wrong. probably have a leak somewhere. my car got deeper when i put this combo on,




yes they do. i have a 2.5" downpipe on my car from zzp.

 

I have the Vibrant comb. Sounds like a Civic when the exhaust is cold but when the baby gets nice and hot, it is one deep rumble. You will also find that there is a loss of power below 3K rpm but the car really wakes up between 3200 and 6500 rpm. This exhaust is proven to add a min. of 1 lb of boost to the LSJ engine in the mid range which is good for 12-15 hp.

man u do not have a 2.5 downpipe u have a 2.5 flange why dont you email them and ask if they make 2.5 downpipes for your car.

 

I have the GMPP sport & Vibrant, I love the sound! Here is a short Video of what it sounds Like & yes it bolts right up!!

 

you're talking about just the regular downpipe. i'm talking about the downpipe that comes with the mid-lenght header, which is different. and i assure you that it is 2.5". look at their site, we're talking about 2 different products here.

 

mines ceramic coated....ive only got about 150 miles since install, but its holding up perfectly fine, and i pushed the car for everyone of those miles. not even any spiderweb cracks or anything.

 

Awesome! Great to hear!
