Octavia III Exhaust Thread

[99Reza]

Scott, thanks for sharing your experience and your thought. That's awesome and exactly what we need to hear.

What dimension is the resonator that you have installed on your current car? Any particular brand?

Would be very interested to hear how Hitech muffler sounds on our car (a plus for being a local manufacturer too), might have to put a hold on my muffler project until you have finished with yours

Quick update: Installed 18 inch long bullet/hot-dog style resonator the other day to see if there's any changes. The sound from inside the car is very close to stock with slight growl at low rpm. The harsh note previously experienced is now replaced with subtle deep bassy tone. The DSG fart is still there but very2 subdued. I have yet to push the car with the resi on, so can't give comment on the high rpm/WOT sound, it will probably lose the awesomeness at high rpm.

I found the 18 inch resonator kill too much noise for my liking, especially straight from no resonator. My main goal was to remove the dreaded harsh note thus choosing the 18inch, turns out it was too effective on doing that. For those coming from OEM setup (well, we all are initially), the noise increase from the 18inch resi will probably be enough for most people.

If I were to do it all over again, I would replaced the stock resonator with a 12inch or possibly smaller resonator and call it a day, the stock exhaust has actually a nice character already.

The cost of the resi was $50 bucks and cost the same for installation, took only half and hour to fit, it's a reasonably cheap and quick mod. This is a glasspack resi, eventually the packing will burn out and need replacement, those are the only type available from my exhaust place. A longer lasting steelpack or ceramicpack can be sourced reasonably cheap from ebay I think.

Nice update Reza! I'll definitely give the 12" resonator a go. I might couple it with a sports cat setup later down the track too.
What diameter are the OEM pipes? I think I'm going to keep it as standard and not go up to 3" pipes on my Mk3.

[99Reza]

The standard pipe is 2.25" in diameter.

I've been eyeing Jetex component for a while, I might give those a go later down the track. Hopefully our dollar is stronger too .

[Fireside]

Cheers thanks!

Yeah I started having probs with the full bore 3" Miltech, not much back pressure meant every now and then I'd stall at idol (on a DSG) so I doubt I'll go past 2.5" system.

[99Reza]

Oh wow really? even with DSG? I didn't realise changing the pipe diameter can have that effect.

I do notice that since putting the 18inch resi on the exhaust the car feels stronger than just with straight pipe. Maybe it's just in my head. Perhaps the exhaust noise level is now more balance with the engine noise and alter my perception regarding the car performance.

[zei20t]

backpressure? the turbo is the back pressure, you may have had other issues.

youll probably get better results (tiny) with a 2.75" cat-back. the exhaust has cooled and you want velocity to get it out faster. 3" probably wouldn't be as effective, but to the average joe, youd never notice.
