R33 Stock Dump Pipe Size

[paulos]

i was taking a look under my car today as i was hoping to get a dump pipe and high flow cat fitted to my car

it seems that the dump pipe which is on there is just as large as my custom cat back exhuast which is in between 3inch-3.5inch im not to sure honestly

but its a big bloody pipe thats for sure

does any body know how big they noramly are stock as i have no idea????

also getting some prices for aftermarket ones fitted getting prices like 950 the cheapest so far is 750 with high flow cat fitted seems to expensive for a bloody pipe with two bends in it.

cheap ones here, bolts right up to stock turbine housing. i'm using one on my r32 had no issues so far. cats are over rated

cats are over rated

This is crap.

A good flowing cat is a must if you hope to get the most out of your setup.

if you want to upgrade the stock dumps go for a pair of BNR34 items

they are larger and should be a direct fit to your existing stuff
