isuzu dmax 2010 exhaust

Jack p1
First of al,l a dump pipe is the bit which goes directly from the outlet of the turbo exit flange and is generally a wide oval shape which has it's large oval size, maybe 4" oval, gradually reduced to a size, commonly 2 3/4" or 3" depending on model.
The drop pipe which is next in line often has the large size, maybe 3" reduce down to the continuing pipe size used for the rest of the system ie 2 3/4" or may even remain the 3" size and it is continued right through.
I believe both sizes of exhaust are available.

Probably for normal use 2 3/4" will suit you well, Beaudesert sell that size while other brands may offer the 3". I don't think you will notice any difference between the two sizes but the larger might be harder to fit and clear all the gear and provide good positioning of all components.

You don't say if it is a dual cab with tub or tray. check your model carefully as there is some differences and one Dmax may not fit another Dmax.
The wheelbase of a dctub is 3050mm while others are 3200mm so yes there is a difference so you must get the correct one. Be aware of this when ordering/buying.

thanks guys just some people been telling me go for the 2 and half inch then some say 3 would be better i have the 2010 damx LE duel cab with tub in the LS model its only a 3.0 L turbo would it keep up with the 3'' exhaust

Hi jack p1

I have Colorado dual cab 4wd 2010 model put 3" exhaust right through including dump pipe got it from mob in Bris within 24 hrs fitted perfect did it myself had to modify heat shield at turbo flange slightly took about three hours without hoist on my own.
Results very inconclusive fuel consumption the same although did appear to have better performance through gears and better response from accelerator.
A month later put in K & N sports air filter which appeared to help acceleration and mid range torque also marginally better fuel consumption say 1 litre only, have now done at least 25k with this setup towing 23' van presently 68klms east of Southern Cross WA ,
Yesterday did 397 Klm starting east of Balladonia WA through Norseman to Kalgoorlie, were I filled up this morn with 56.31ltrs you can work out the consumption.
Please note yesterday there was none or little wind 25deg day rolling hills not using aircon till Norseman Kalgoolie leg run it at 85 to 95 in fifth but 4th below 80klm/hr(please note on windy day fuel consumption can see worst of approx 16 to 18 ltrs/100ks but my van is like a sail.
Exhaust cost $900. Air filter $100.
Hope this info helps

Jacko,
check out Beaudesert exhausts. They do a lot of R&D and I think theirs is 2 3/4 inch system.

Bigger is not always better.
