Vti-r exhaust size

[quang]

sorry just a quick one, i searched around but everyone is talking about vti's or gli's none for vti-r's, which one would be better 2" or 2 1/4" all the way through (i.e headers, hi-flow cat and cat back). Is the performance difference the same as the sohc engines or would it be different for the dohc?
thanks :D

most common size for cat back would be 2 1/4 inch.

i went for a 2 1/2 inch and its not too bad.

2 inch is too small for the B16a me thinks

[tRipitaka]

i think this has been covered before,
but u'll see that most people will recommend 2 1/4 inch, as it is an all round performer..

[sirvtec]

go 2 1/4, with straight through cat.

[samsider]

i got a 2 1/2 inch stainless steel exhaust all the way through with extractors

once i hit 5.6 revs (vtec) the exhaust screams

[CONAN]

5" all the way !!

nar sorry, my recommendation would be 2 1/4", so would most exhaust shops.

Maybe u can get some japanese brand sizes, cant go wrong there.
i.e trust, toda, mugen

i wouldnt get any bigger than 2 1/4 as any bigger is just waaay too loud.

[Hondavirgin]

don't most of them work out to be around 2 1/4 i think or a bit more? 60mm?

[Astro]

2 1/2 inch is good for me..

gain some good top end :)

[Fro-Daddy]

im guessing thats 2.25 press bent?

[Astro]

nah man 2 and a half mandrel bent

[DNYALL]

2 1/4 with hi flow cat and 4-1 headers = :thumbsup:

Mine made a very decent performance improvement

[raff]

2 1/4" all the way!!

with high flow cat and headers

[hkcivic]

Whats the stock size for a Vti-R 2"inch?
I heard that Type R is 2 1/4 inches is that correct?

[CONAN]

what car is this car?
brand new or used?

got a picture?

[steve]

sorry 2 jack ur thread but do any good brand name headers come wit a 2 1/4" collector? i kno spoon/mugen/toda all come wit 2 1/2" collector, meaning its prob best to run 2 1/2" all the way thru, if running these manifolds that is

[quang]

so is 2 1/4" still good for everyday driving with the vti-r's? or do you lose a bit down low?
also what hkcivic said does anyone know the stock exhaust size for the vti-r's?

[pillow]

You've driven my car Quang, did it feel like it had less power than yours down low?

[**Ghost**]

stock exhaust size for EK4 (i've measured myself)...

this is going to sound weird but from cat to the final "bend" its 2 inches... but after the bend to the muffler its around 1.85inches

[J-MuN]

2 1/4" is the best imo...
