Wow thanks to everyone who replied and took their time to explain it in so much detail. However my current system is an axle back with a straight through muffler, not a muffler delete, so the effect of a resonator delete might not be the same as for you guys. But your feedback is still very useful. 
 

another question i have is that the sound of the exhaust comes back to almost stock at high rpms which i find weird. Is it the axle back pipe being larger that the rest of the pipe? Im not sure how big the pipes are from the 3rd cat but the exhaust shop did install 2.5 inch pipe after the y split. Any ideas?

Is the resonator delete louder compared to a hotdog resonator, or is it just raspier? Looking to make my system louder but not sure whether hotdogs are worth it compared to a resonator delete.

It looks beautiful Jay. Super clean with a nice stance to match. Just be ultra careful with that front splitter when pulling into front kerbing. I always make a habit to back it in wherever I can, not that my car is low, it's just what I do anway. Much easier getting out too when you have better vision across the bow.

Well done mate 

Thanks man👍🏽

Claims seem to be anything from "no change" to "huge difference". I honestly couldn't notice a difference, unfortunately. Was expecting something - a placebo if anything. 

Though, if you can do it yourself, it's probably worth a try/to experiment. 

The only way to find out is through a dyno run unfortunately. I’ll have to find another way to add power while keeping it n/a.

I seen one of these today & particularly noticed half the muffler shows along with the entire tip from a side on view. The tip would have to be welded straight onto the muffler or would look funny, if ya know wat I mean

I wonder if a Mercedes diffuser could be grafted on.... 

Yes that’s what i hate about the stock tips because they shows the tiny pipe inside.😂

Similar to yourself I have previously reviewed a number of threads on this Forum about this Y pipe modification. I understand that the torque curve mores more towards the top end.  This does not suit my driving style and conditions where I prefer more torque in the lower rev band.

I made particular note of 1 post where the member did this modification then changed it back to factory standard.

End result is that I upgraded the rear catalytic convertor to a high flow one. Not going to give it a personal recommendation but something to consider as an alternative.

As a welder, you should be able to easily change this rear catalytic convertor and change back, if required.

Appreciate the feedback!

I agree with Metal_Head about using widest possible oval tips. I think that it will better suit the Aurion from an aesthetics perspective. Also consider a slanted cut for better ground clearance when vehicle is going up or down a sloping driveway.  

Im not the biggest fan of the oval tips but i will still consider them. As for the slanted cut, that is a must now that my car is lowered.

Regarding exhaust mods you have to choose mufflers carefully. You may spend 700 bucks and find u can barely hear it, or...... The drone will drive u insane. I went with a pair of redback A534GP resonators along with 100mm tips which I found fairly quiet so I had the middle factory resonator removed, whereas another member here found them a bit boomy. Everybody's ears are different haha.

https://au.toyotaownersclub.com/forums/topic/58070-rear-muffler-delete/

A pair redbacks are 140ish and tips less than that. Get some more quotes

Cheers man, greatly appreciated. I’m wondering if 4” tip is too big or not or if i should go with a 3.5” instead. Here is a comparison of the 4” and stock:

I have read through the collector pipe mod and as a welder i might consider doing it in the future. Although i still cannot determine whether this mod is worth it or really does make a difference because there are no dyno results. Also, does it provide extra low end torque power or top end? Below is the photo of the collector pipe where it squishes up as it joins together.

As campbeam mentioned, the sportivo already has an upgraded rear sway bar so I wouldn't bother. If you still wanted less understeer, then make use of the coilovers and dial in less negative camber in the rear than the front. Example: fronts set at - 1.25 deg & rears at 0.75deg

Thanks for letting me know before i wasted my money!

When u say axle back, do u mean just the rear section (2 mufflers)? 

Basically the axle back is everything after the 2 flanges that connect the exhausts.

That's a sexy aurion, welcome. Regarding police, there's not much u can do as the "P" plate attracts their attention from the get go. If u have a driving history then it just gets worse from there. 

What will be the specs of the exhaust? 

Thanks mate, 

I am not too sure about the exhaust yet but the guy quoted me mild steel piping and sports mufflers with either a 3.5 or 4 inch stainless tips. In total he quoted me 700 which is abit pricey for an axleback in my opinion but the shop is highly reputable with 10+ years of experience. Let me know your thoughts if this is too expensive.

I have to say the stock brakes are excellent and stop very well so not sure how much better a 2 piston caliper will be. The Stock Aurion caliper has one big piston whereas the Kulger will be two smaller pistons. So is it a case of a placebo effect ? Who knows.

If that’s the case it may not add too much braking performance but i’m pretty sure it’s not a placebo, it’s definitely there.

Thanks Campbeam,

i will be looking at good quality tires in the future but as of now the set that i have on will do, for daily driving. No police have pulled me over yet and hopefully putting on the exhaust won’t attract them. After all, its a little sleeper car.😉 And the exhaust that i want to put on are not extremely loud, but just abit louder and better tone than the factory.👍

The disc and brake pads are also in really good condition and brakes well but i do want the klugger 2 piston calipers.

Welcome to the Forum. As a P plater, suggest that you keep a low profile to avoid unwanted Police attention.

The Sportivo already has an upgraded rear anti-sway bar so maybe a bit of research to confirm whether it will be worthwhile.

Best value upgrade is a set of quality known brand tyres. With 18" wheels, there is a good choice of sports performance tyres with excellent grip.

Have a search on this Forum about what disc brake pads, members are using and recommending.

I have a set of braided performance brake hoses on my eBay watchlist but unlikely to buy because I mainly drive sedately and avoid hard braking situations.

Hello Jay and welcome to the forum mate.

Your Aurion looks shmick and tastefully done. The ride height is spot on. too. Well done. 

We will need more photos 😄

Thanks tony, 

I will definitely upload more photos when i get to wash the car and take proper shots. I’m also keen for the exhaust which may be installed in 2 weeks time.😁

Hi guys i’ve been lucky enough to get myself a 2016 toyota aurion sportivo as a p plater in SA. I’ve always read through this forum since my ownership but only decided to join now. I am abit late but who cares, up the aurion! The mods i have done to my car are as follows: 

- 18x8.5 +35 aftermarket avid av32 wheels in gloss black (i should have bought real wheels but i was in a rush) 

- cheap tires size 245/40/r18

-  gkteck extended lug nuts

- bc racing br series coilovers

- rolled rear guards

- pedders camber pins 

- tailight & reflectors vinyl tint (light smoke)

- gloss black ebay rear window spoiler

- custom slim plates with glass cover

No interior mods because i dont think it needs any. As of now i have not seen any gsv50 aurions done as clean as this one in SA. I am planning also planning to put an ultra racing rear sway bar and get a custom axle-back exhaust installed by a shop in the future. Here are some unprofessional photos of my dirty car.💯
