R32 Gtst Cat

[WAN73D]

hey guys.

just wanna know if this is the stock cat or not for an 1990 r32 gtst. i have a 3 inch cat back system...just dunno about the cat.

wanna know cos i wanna complete the system so need to know if i need a cat as well

also IF this isn't the stocker...then will it bolt up to one of those 3 inch JJR dump/front pipes from just jap?

thanks for the help

(have searched...found no pics)

ps those pics are taken looking from the front towards the back so the pipe entering is the stock front pipe (left) ...covered in heat shield i think

You need a new high flow cat!

dag namit..... so that's gonna havta go as well...hehe

on another note i got my exhuast tested and it was 85db (legal's 90db in NSW) the exhaust is a HKS 3 inch cat back (obv not including cat) and has a resonator along the line as well....its not that loud right now

question: will putting in the 3inch dump/front and high flow cat dramatically increase this level. like i've heard decibels are not linear...its sorta like 3 decibels is almost double the current sound that we hear....so surely putting the rest of the 3 inch in won't get it up over 90 db will it???

just wanna know if people with the full 3 inch usually pass noise tests??? (ie under 90 db on an rb20det)

I have split dump, 3" front pipe, 3" super "hiflo" cat "pipe" into a 2 3/4" cat back with only the canon at the back.. nice idle noise, bit droney at 2000rpm in 5th but over 4000rpm damn does she sing
