Will you get burble, crackle, by changing exhaust without ECU tuning?

Will you get burble, crackle, by just changing exhaust without ECU tuning?
Let’s say Akra or FI exhaust - catback, no downpipe

You need a tune if you want burble

No.. maybe a little burble but for the most part you need the increased air flow. You can upgrade your exhaust to get more, but a tune and intake will make everything sound 10 times better.

I have a burble with just the akra

Did you get a new downpipe with akra? or was akra catback? Tring to figure out if the burble is related to a new downpipe or not.

Mine will do it with comp exhaust on downshifts and revs.

Flying Ace · 05-23-2018, 12:20 PM

no, again, we all have stock everything except the exhaust. Even stock CP exhaust will have the burble.

Mine is akrapovic evolution which is same as the m performance exhaust , i have stock downpipes , i run 93 octane and it sound nice with little burbules and some times bangs with hard shifting in manual mode , i have also ecu tune but without the bang and burbules option .

I have an eisenmann race on stock tune and downpipes. I get some pretty crazy Pops and backfire on deceleration. ECU tuning will provide a lot more Pops and crackles though. Really depends what kind of sound you are looking to get

No, and I wouldn't recommend it.
