Does $$$ buy you a better sounding and performing exhaust? AVO Cat Back Exhaust Review

After one too many fault codes coming up it was time to fix the exhaust with a quality system from AVO through OnTrack 4x4. If you like hearing v8's on the loud pedal there is plenty of it but some good info too from dyno testing and comparisons

[@MudducksTouringAustralia]

Now that's how a V8 should sound!!! Awesome. Cheers Steve

[@daveclarke1466]

Just a great sound! Big improvement.

[@etonymouhanad3020]

Nice job man, I put Magna flow on mine and the sound became cool, this the only thing was missing on the Y62 cool sound

[@davekent762]

So much better!!! The resonator alone had that tinny sound. The new exhaust has an awesome throaty V8 sound 😍

[@brettjohnstone5829]

Sounds much better, Dave! Got rid of the crackle with the centre muffler delete

[@chrisoh6627]

Ditch the cats and put a snorkel on it with a huge filter ELEMENT in a sealed box then tune it! Haha. A good catch can system would probably help too! Running huge tyres might as well go the whole hog! I had a pretty wild naturally aspirated V8 with head work, cams, intake manifold porting, extractors and tune. Biggest gain apart from race fuel was removing the cats. They choke up a naturally aspirated engine soo much. The gain was over the entire dyno graph too and torque as well.

[@EXTRAWALEED]

Nice sound

[@TheHayabusa09]

Great stuff!! Reckon some extractors are next on the agenda.

[@DASHOffRoad]

Some extractors with a turbo on the middle???

[@aedeau]

new set up definitely got rid of the straight pipe, thong-slap sound, but it now sounds kind of stock. not sure i'd be too happy with that massive rear muffler (axle back) either. wonder how longer before you rip it off when off road? maybe try unbolting it and replacing it with a hot dog axle back to get your clearance back? Also, you should have looked into a custom length J-pipe with your old setup. It would have got rid of the drone but kept the loudness.

[@shreckm6470]

Put a Manta 3 inch cat back to diff $750 fitted and it sounds awesome none of that horrible cackle or droning when towing and lot of people have commented on good it sounds.

[@travismoon5290]

And coming back to tuning, what if I do not have a unichip? Should I still do a tune?

[@ptnzync9015]

Great vids Dave, I’d be curious to know what system you liked the best out of the ones you have tested and reviewed. Like you towning 3tn caravan, want I nice sound that isn’t over the top.

[@DASHOffRoad]

My favourite is the DASH system, that’s why I put my name to it 😅

[@ptnzync9015]

I’ll be in touch Thanks again mate

[@darrenwilkes3613]

Ok so I love the sound, What is the brand of this exhaust and is it a full system ?

[@DASHOffRoad]

AVO system from Ontrack

[@stephenwarren55]

If your first exhaust note was with the stock muffler, your exhaust note in the AUS is way louder than the stock exhaust note in the USA.

[@dolf3288]

Did you heat shield the new exhaust in the same spots as the factory one by any chance? Do you recommend doing so? Cheers

[@DASHOffRoad]

Negative. I don’t think anyone bothers

[@plakic]

Why not show the dyno numbers? They're useful for calculating a percentage increase across the rev range. Thanks so much for the content.

[@brettleonard8602]

Without extractors anything less is pointless in tuning and gaining power. Anyone who says otherwise is lying. That should answer your question mate.

[@rooster8039]

That's rad...That sounds fat...👌😎🍻...

[@ravscin]

I wish to put VK engine with this resinator to old Y60 and low it down :-)

[@Jay-_-Lee]

2:32 i'm not seeing any grin... not sure if you are actually happy with new exhaust or not.. sounds better in our ears anyway ;p

[@DASHOffRoad]

I’m very happy, and so is the family as they can speak to each other without drone now

[@ecithump]

Maybe it's me, or the mic, but there sounded like minimal change in drone between the 2?

[@DASHOffRoad]

Yeah, most mics are designed to get rid of that sort of noise, tried to use my phone to pic it up. I can assure you the new system is heaps quieter when cruising

[@geojase]

I am getting codes all the time now too....2013 build Ti-L 98k km....already has a CAT back exhaust....will putting the AVO second cat delete pipes help?? want to avoid the cost of a full system

[@DASHOffRoad]

It will help the system flow but the o2 sensor is before the rear cat so won’t help you with codes sorry. Speak to OnTrack about the “Super High flow” front cat

[@geojase]

@@DASHOffRoad got a website for them? My mechanic is telling me to go back to stock but dont think that will help either

[@DASHOffRoad]

Just call up OnTrack in Vic. I used to clear codes daily, now I haven’t seen a code since

[@MrMug4d]

I'd be interested to see if t there are any more gain with high flow car and performance extractors too.

[@DASHOffRoad]

Especially if those headers had a turbo in the middle of them

[@MrMug4d]

@@DASHOffRoad imagine that!!! I'd be keen to see something like that.

[@siralswidi]

i want my nissan to crackle like the svr range rover haha is that possible?

[@Stevegrande1]

They sound awesome

[@sammccarthy3736]

What are the straps on the inside of roof for?

[@DASHOffRoad]

Haha, just tying pillows up out the way on the inside of the roof. Was pretty loaded for this trip

[@sammccarthy3736]

@@DASHOffRoad good idear, i always try shove mine in a bag and end up ripping the bag

[@Stevegrande1]

I think your own centre muffler sounds way better that is in your other video. Much better burble with your one with out the cabin drone

[@titanx04]

When’s the supercharger going on?

[@DASHOffRoad]

Not interested in a supercharger

[@psy06]

sounds good but i recon it hangs pretty low, 1st time you slide off a rock, its gonna get rekt

[@060racing8]

A nice engine with a nice system that ends up sounding like shit because of an automatic transmission

[@MrMarkota85]

How much power did it make?

[@DASHOffRoad]

It added 16kw just by bolting it on

[@Rawsz_27]

better than land cruiser

[@maasai-]

The new exhaust looks like a cow calling its little child.

[@A.J.1656]

Loud exhaust on a truck is like loud exhaust on a Harley Davidson, you're making a bunch of noise for no reason. If you want to go fast and make noise get a fast car or fast motorcycle. Okay, I'm just bitter that the 4.0 in the Frontier sounds like a Honda Civic with exhaust. I'll put exhaust on it when I VK56 swap it... but loud Harleys are retarded.

[@mawhite000]

Resonator....

[@norcoshore6816]

Nothing special, sounds crap

[@geojase]

competitor trolling LMFAO.....sounds fkn great....

[@iampennochio]

Sounds way better than my td42 thats for sure.👀
