what's a better catback for dc2r 2.25 or 2.5??

[jetdc2R]

just thinking on what catback size to get made up for my type r

[gach2]

stock dc2r is 2.25inch (might be just the axleback)
id recomend 2.5 inch mandrel bent

[joe.teg]

2.5inch catback is a bit big
go 2.25in catback with hi-flo cat

[geeang]

2.5" catback is not 'a bit big' at all, stock DC2R is already 2.25 so it's better to go for 2.5" to take advantage of the upgrade.

[joe.teg]

sorry
i was unaware that they were 2.25" standard. i thought gach had made a mistake
my mistake haha

[jetdc2R]

hmm....yeh 2.5 sounds good, im running j's racing headers and if i get a custom made stainless steel 2.25" cat-back with mandel bends, with a 1 resornator, and high flow cat, and a nice cannon..... will i notice a difference from the stock catback?

[jetdc2R]

lol haha joey u wanna put dc2r catback on ur v-tir?

[joe.teg]

hahah nah mate im duin a 2.25" custom cat-back with hi flow cat but i wasnt sure what the ITRs came with lol

what do u think

[DLO01]

Get some good headers with 2.5 inch collector. Run 2.5 inch hi flow cat back exhaust.

[jetdc2R]

ahk kool

yes i agree
why go backwards and waste money on a 2.25 inch exhaust
2.5 inch all the way

[cris88]

i know wat will solve this problem straight pipe 2.5" lol :P

[VTECMACHINE]

You guys sure stock ITR is 2.25 inch? I swear mine was alot smaller!
All the japs use 60mm for DC2R, which is 2.36... inchs. So I would stick with a 60mm pipe :D

im with you on that one ay
ive got 60mm with my exhaust :D

[Tegzieboi_BAR]

accordin 2 team-integra a USDM ITR is 2.14 inches or thereabouts from memory so i would hav thought AUDM would b similar... really doubt its already 2.25, maybe jdm tegs r though.

[joe.teg]

yeah i was under the impression that the exhaust on an AUDM dc2r was closer to 2 inches than 2.25 inches. i say for a catback go somewhere in between like a 60mm which is 2.36 as mentioned above. with a catback it wont make much difference unless your doing headers but the dc2rs have a good set already

[VTECMACHINE]

I just had a look at my stock exhaust, and it's no way near 2.25 inchs. Close to 2" i'd say.

But yeah, 60mm yO!

[VTECMACHINE]

Yeah, is the JDM one different to the AUDM one? I'm curious now... Thanks mannngggg!!!

56 mm

[joe.teg]

see 56mm is 2.20 inches and thats the JDM model is it not?

yeah jdm crap
aussie stuff better lol

[joe.teg]

haha
so what size would be most beneficial for a AUDM DC2R

[90LAN]

jdm 60mm or 2.5"

[hondar]

guys

if you custom made best size is 2.5inch measured on outer diameter of pipe

if japanese brand, it is 60.5mm measured inner diameter pipe

why measured using inner diameter? most good jap brand use thick metal that cause less droning and vibration sound as such if you measure them using outer diameter, it is almost 3 inch thick

Correcto!

My 2.25" fujitsubo is ****ing thick which is why it doesnt make the pinging sound :)

[duckey]

lol haha joey u wanna put dc2r catback on ur v-tir?

why? u selling dc2r cat back?

[jetdc2R]

im taking off my standard dc2r catback to build a new exhaust

[BlkR]

i wonder how much is it for a 2.5" bpipe to be done ?

[apparition]

I reckon that you might be better off getting a Japanese brand cat back exhaust rather than a custom made one which would just bolt straight on. I think my Fujitsubo RM01 was 2.38" (I might be wrong). Really depends on your budget tho.

[VTECMACHINE]

JDM "Vision" B-pipes are a fair price! Ask Leo from JDM concept about it.

bankstown muffler fit
do it for 300 2.5" cat with canon exhaust
