Octavia III Exhaust Thread

[Lucas_R]

How about VARDesign / Viezu? Supposedly Australian made exhausts?

Havent they gone out of business in Australia? Many of their previous resellers are no longer dealing with them, including Greg (Carformance) and Transporter.

Ah no idea, looks like it may just be a last ditch attempt in social media. LucasR is DNA tuning still around? I have been looking at alternative tuners and remember you had positive things to say about DNA. Don't suppose they have a hardware partner?

Yes - DNA are still in Melbourne, i had my GTI tuned about 6 months ago by John at DNA.

No hardware though, they only do tuning.

Got quoted $1650 and $2200 for a Milltek catback for the RS. At that price i may go custom or just a resonator delete.

ouch for a catback?? horrible pricing. go custom

Yep. Australian dealer. UK pricing in line with it too, though i suspect shipping adds alot to that price.

That price seems to be the norm for complete cat back system for RS. Bull-X and Fox system is similarly priced.

The resonator delete is great for what it cost, but there is brief resonance at around 3k rpm with 3/4 throttle or thereabout, more noticeable during warmer weather. I've done few thousand km with it, it has improved considerably but it's still there, i think it will be there for good. Not sure if it has something to do with the workmanship or just the character of the motor itself.

Perhaps experiment with Mufflers delete instead

I'm looking at piecing together Simons/Jetex component. One resonator + 2 muffler with shipping from UK is just under $600 bucks. I will most likely going to keep stock pipe if going this route. From reading around the net, Simons muffler is probably one of the quietest performance muffler out there.

I may just remove the large resonator and put in place a small hotdog one. Though I want to see what the car sounds like with an after-market DP first. It may produce enough sound for my liking. I'm just itching for more exhaust note, that's one thing i'm not happy with on the RS.

[99Reza]

I was thinking about putting small resonator to get rid of the resonance. More cost-efficient. I'm pretty sure the OEM muffler is straight through design.

As a sidenote, the resonator on Gti mk7 look exactly the same as ours from the outside. Looking inside there is one major difference, ours is straight pipe with perforation all the way whereas the Gti one is pretty much solid pipe with oval hole in the centre. GTI has deeper exhaust tone compare to ours.

I have been reading this thread for awhile Re exhaust for my upcoming VRS TSI. I have used my current car as a guinea pig (2012 MK6 GTI manual) I like 99Reza did a resonator delete to see what effect it would have, the GTI sounded much better on full throttle and a bit deeper and tougher at idle but had the same 3000rpm harsh zone on part throttle. Having today just fitted a small hotdog style resy the car is transformed. Volume has only decreased slightly but the harshness/resonance has gone. After this experience my plan is to maintain the std piping but replace the rear mufflers with a quality smaller set of rear mufflers and tune the sound with a straight through resy. The great thing with the resy is if you need to change it to either gain or increase volume you are only talking about $150.
All up I think a custom setup shouldn't cost more than $600-700 retaining the std piping. Then when you sell it you can always reinstall the std setup for a small cost. Just my two cents worth. As has been said before the RS just needs a little more beef to the sound to really give the car the edge it deserves, then turn down the sound gen a bit.

I'm planning on using Hitech mufflers as I had one of their full cat back systems on my R53 Cooper S which sounded awesome with plenty of pop and farts on the over run but no droning on the highway. I am based in Melbourne so I would buy the mufflers of HItech and get my local guy to do the fitting.
