Default 95 Turbo - where'd my exhaust go?

Hi guys, just turboed my 95 miata with an SR20 T25, FM mani/outlet/downpipe, magnaflow HFC & yonaka cat-back (2.5" exhaust). Got tuned to 185whp/175wtq @ 11psi. Feels solid, however the new intake noise totally drowns out my exhaust. What do you think I can do without affecting my brand new tune?

FM air box & hush kit? https://www.flyinmiata.com/na-fm-turbo-hush-kit.html (should fit w/ my current intake setup)
Resonator delete?

If you would REALLLY prefer the sound of your exhaust I would recommend building an intake box to reduce intake noise. Otherwise just enjoy the sound of the force of 1000 winds!

spool noise is the best noise.

Anyone know whether either option would likely affect my tune, and would the resonator delete sound decent? I'm sure I will still hear the spool...

If you don't enjoy the sound of a compressor intake spinning up, there's not much that anyone on this forum is going to be able to say that will help you.

Best case, buy the latest Nickleback album, and turn the volume up.

Jerry rig a stock airbox into the turbo intake to quiet it down and chop off your muffler. you will get your exhaust sounds back.

Yeah so just tried removing the muffler last night to see what it sounded like... no thanks lol. Too loud and doesn't sound good either. I'd consider swapping the muffler but don't know anything that would mate up to the yonaka mid pipe, so thought resonator delete would be the best route...

Intake noise drowns out exhaust
Doesn't want louder exhaust


Make a cold air intake by running hose/pipes from compressor inlet to front side of radiator somewhere and mount filter there. Piping will quiet the noise some and location will make it more difficult to hear from the cabin.

Also, some cone type filters come with enclosures that allow a hose to be mounted on them.

Just get the FM airbox. Not really for the sound, but it's just a good thing to have for reducing IAT's. Otherwise, upgrade to a proper 3 inch system.

Sounds like you want an all motor setup. With my 3in exhaust MKTurbo setup, once boost comes on there is no more hearing the exhaust really. I can hear it at lower rpm's, what's so bad about hearing the turbo over the exhaust? What Six and Goingnowherefast said are about you're only two options. Though like I said, 3in isn't much improvement in the sound department imo
