Cheapest way to get louder pops?? (Without catless dp or tune)

M2CBoi · 03-27-2021, 07:27 PM

Just picked up a 2019 HS M2C DCT!
Absolutely love the car, but was wondering what would be the cheapest way to get louder pops without doing a catless downpipe or tune? I want to be able to pass emissions with no problem.

Midpipe (catless and non-res) is your only option. Still will pass emissions.

Thanks for the reply - any recommended vendors?

If all you want is louder pops, a flash tune such as BM3 will allow you to adjust the duration and aggressiveness.

Cap gun out the window.

Do they still sell those things?

AA Single midpipe.

cheapest would be just put down the back seats. More noise will enter the cabin

1/2" drill bit. Drill hole in front of or behind resonator depending on how loud you want it.
Slip a band clamp over the hole when you want it back to stock.

We've got a winner

Aa single mid will blow you mind how loud the overrun from 6-7k can be. Straight up 5-6 gunshots in a row.

AA Single Midpipe +1
AA Signature Cat-back +3

Tangent trigger warning: I'm still in break-in mode and don't notice a difference between Sport and Sport+ in terms of the exhaust. Does that change above 5500 RPM?

Yeah S+ gives serious popage

It's like:
3k="burble burble"
5k="crack pop burble"
7k="snap crackle pop"

Sport mode subdues the burble to be really tame.

If I were you(and I once was) I'd:

Put down back seat(better sound)

Turn the car on - put it in S+ - touch the gas to open the valves - turn the car off - go in the trunk to the fuse box - pull the 2 that relate to the valves - turn the car back on - and enjoy a way better experience

Then paint your muffler sack
