Hi guys!

I've been a very satisfied owner of an i30 SR (PD) - also my first ever Hyundai -  for roughly 3 months now and everything I've experienced with this car has been fantastic (massive step up from my manual VRX Colt) but I've had one question nagging me for a while now and it is this:

Why do the US delivered Elantra SRs (Elantra Sport) and i30 SRs (Elantra GT Sport) get amazingly sounding stock exhausts, while we get a wheezy one with only a subtle hint of a burble? Looking at a couple of YouTube videos, and it's very clear that the US delivered models sound pleasantly aggressive with all the pops and crackles and it's making me wonder - what exactly is making all the difference in sound?

I'm no exhaust expert, so if someone knowledgeable can chime in with any info, that would at least give me some closure (lol). I'm curious as to why Hyundai would give the US a sick exhaust but then leave all the other regions with the petrol turbo models high and dry?

PS. Still love my SR to bits though.

Congrats on your choice and welcome. I would say the easiest way to make a difference is the choice of muffler. In the bad old days you could replace the muffler with straight through pipe or a 'hot dog' to reduce back pressure and free more of the angry rumble.

Take your You Tube video of the exhaust you want to a custom exhaust specialist and see if they will replicate it for you or make a better one for you.......

Any link to the videos in question? the US might offer an optional exhaust upgrade during purchase if they sound different unless the owners have done them privately.

From my brief lookover of the PD turbo the exhaust is quite good though the rear muffler is a huge monstrosity, you could opt for another 1 in 2 out straight through design muffler in and end to end type design like the first pic below if it's possible to get it to fit with minor modifications, or! you could also go for bottle type hotdog resonators...one for each side.

I considered something like Craig suggested when he first mentioned it, but from my experience these mods result in more noise at cruising speeds too which I prefer to avoid.  :cool:

Most of the crackles and pops I've heard have been on videos of the i30N (a different beast altogether)

PS. I love my SR too..  :happydance:

Hey Craig,

Inot sure how to post YouTube vids here but here are some links to clarify the obviously more aggressive exhaust:

Elantra GT Sport (i30 SR):

Elantra (SR) Sport:

:link: 2017 Elantra Sport Stock Exhaust - YouTube


And this seems to be only videos from north America. No mention of an optional exhaust system, as it seems all US bound Elantra and i30's sound like this.

You wouldn’t have to worry about the droning sound Dazz, with standard headers and the big factory resonator you’ll just get a nice note and the sports muffler or hotdogs will prevent the drone, similar to when I just had the rear muffler changed on mine and no other exhaust mods.

I can only go on what the videos state that they’re stock systems, if so then they must be different muffler setups.

The last video clearly has a different muffler to what is used here, it’s likely the US are also using group 5 catalytic converters now too for their emissions standards where I think Group 3 are still used here...maybe group 4 on the new model :undecided:

I see... Well if that is truly the case, it is unfortunate that we get a different muffler setup to the US. I've actually haven't had the chance to look at the underside of the SRs derriere so i wouldn't have known it was the muffler...

Cheers for clarifying that though, mate.
