Hey guys,
Did a search but seem to have come up short.
Hope I looked properly.
What do people think is a good exhaust size for a TB45?
Have heard anything from 2 1/4 inch up to 3 inch.
Thinking extractors and hi flow muffler, but what about the pipe?
Also, she will be getting a snorkel later on.
Any suggestions along with reasoning would be great.
Cheers,
Evo
Extractors and eBay catback.Originally Posted by Evo
Mine has extractors, and is in desperate need of a free flowing exhaust.

Hey mate, when I had the 4.5 in mine. I put a 2.5" mandrel bent sports system on from redback. I used wildcat extractors, a stainless hi flow cat and a straight through muffler. It had no drowning noise and there was definate seat of the pants change to the power. It also allowed it too hold overdrive easier at 100kph.(auto obviously)

Considering the 2.5" or 3" route, have access to a 3" cat second hand from a mate (good nick).
Plus I have a 2.4 injected motor running a 2.5" so was thinking 3" on the 4500.
Also extractors.
Was quoted for extractors, full 3" system, $1000 fitted.
This a good price?
Cheers,

Check the vendors thread as there is an exhaust joint that does post nation wide there mate. Pm them for advice on size also. Sorry a diesel man here, can hall with the advice you need. I would think that a 3" was too big for a Petrol??

The only good thing about an 80 series is..... the front end?? Wrong!!, the Engine?? Wrong!! the Full Time 4WD system?? Wrong!! Its the NissanPatrol.com.au stubby holder fitted over the transfer lever.
WARNING: Towballs used for recoveries can, and do kill people and damage property.
Was told 3" too big and fitted 2.5 which is all good. Do the ring around. I paid $800 from extractors back inc high flow cat and muffler.
Cheers 4by
Can I put a Holden badge on my Chevy ?
3" is going to drone really bad. It would do my head in!!!!!!!!

I have been told by a mechanic friend if mine who has owned and loved patrols for 20 years that he wouldn't bother with extractors on my TB42e. Reckons the factory exhaust manifold was pretty good. Said to go 2.5inch, hi flow cat and straight through muffler. That was all that's needed for good all around improvement.
