Exhaust Pops & Bangs discussion

[lc8]

Hello everyone,

Has anyone experienced the fact that the exhaust pops and bang disappear after an hour or so of spirited driving?

I was told that this is perfectly normal, however, for me, half the joy of driving the N is the sound.

As far as I'm aware, this happens because the exhaust gets too hot. Considering the fact that it was only 6 degrees outside, does that means that on a hot summer day the exhaust will get quite very fast?

Cheers,
LC8

Hi,
as I have never been driving hard for such a long time I can't tell. But after cold start your N my exhaust doesn't pop when I lift off. So maybe it's not related to exhaust temperatures but to the engines temperature?

Interesting to know. I wonder if others have experienced this on test drives?

Now that a few have had the cars for a while - can anyone confirm whether the OPs observations are true? Do the pops and bangs disappear after a short time?

On the test drive I was on the 2nd time they did disappear along with the rev matching, but I did have the 4 way flashers on under heavy braking as a bin lorry appeared from nowhere. I just changed rev match from on to off then back on again and all was good! Not sure why it did it but I'm sure having more time with the car will help!

Rev it harder!!

Rev it harder!!

Ha, ha, ha. That’s exactly what the dealer said to me. I’m being all gentle revving to 3000rpm and he’s the one all excited next to me telling me to floor it!

Ha, ha.That’s brilliant. Well, Hyundai have practically told us to do that anyway, haven’t they?!

When you lift off in any gear between 4 and 5k revs it pops and bangs.

I went through a tunnel yesterday and changed from 2nd to 3rd and the bang was so loud a pedestrian screamed

Mine pops and bangs every time too, as long as you take it above 4K.
Regarding the bangs disappearing when hot, last week I drove it on the motorway for 4 hours before putting it in N mode and having some fun on a country lane - the engine and exhaust were obviously very hot but it still popped and banged exactly as it should so there's no reason it should stop after a while.

Anyone experienced a loss in exhaust notes i.e pops and bangs after remap?

I've recently fitted a TDI tuning box and although the increase in performance is impressive I've lost the pops and bangs that came in stock mode. I've turned the box off, the pops are there but very muted. Anyone had similar issues?

 

[coxy 2 carpets]

what are you revving it to?

 

[gmacman]

Depends, normally around 4-5k

 

[coxy 2 carpets]

take it up higher than that mate, drive it like its meant to be, pops around 4-5 are usually muffled but above 5 they should be nice and crisp

 

[gmacman]

Yeah i get that in stock mode but not when the TDI tuning box is turned on

 

[coxy 2 carpets]

Then thats down to the box, obviously the box only tricks the ECU into think it has different parameters to what it does, get in touch with the manufacturer

 

[Mr.Gobsy]

Yeah i get that in stock mode but not when the TDI tuning box is turned on

Which has more worth to you? Popping exhaust or extra performance?

 

[gmacman]

Contacted the manufacturer waiting for a response. Both would be great but performance over pops all day long.
