Turbo spool noise

So I wanna increase my turbo spool sound. Other than DPs and intake what else are some good ways of increasing the spool sound? Thanks in advance

That's literally it.

I was actually surprised that the DP brought out way more turbo noises than the intake did.

I’ve heard from some people that mid pipes or charge pipes might do it. What about a tune like JB4?

You could mount a speaker on the hood, buy an amplifier and wire up a mic to sit near the air box.

Just get a new DP. Even if it's a catted DP. I run the active autowerke catted DP and it's loud as hell.

For intake I'd recommend the $200 BMS one, it's plenty loud, love it

To comply with your question, there's some sound dampening foam (at least I don't think it has a real purpose) you can remove from under the hood that might make the intake a bit louder.

I couldn't really hear spool prior to changing intake though.

Intake costs $200, DP costs $400 for no cat, $800 for cat. Anything else would likely be more expensive. I recommend just getting the BMS intake if you're trying to save money. 10 min install.

Intake helps, I got an exhaust cutout before my muffler and that gave me some more turbo spool. The game changer had to be getting both resonators deleted. I can hear my turbo spool really good around 2.5-3k in manual mode.

Send your turbo to Turbo Labs and get the T51R mod, it's a anti-surge design that is known for having the loudest spool.
