My turbo exhaust is really starting to annoy me and I would like to know if any of you have any success with exhaust combinations that keep power but cut down on noise. Right now I have the FM midpipe and single outlet turbo muffler. What can I do to cut down on the noise? Heat coating, going to twin muffler, custom exhaust, what?? When I get back in town I am going to install the 3.636 ring and pinion gear mainly to cut down on the highway drone. I already have dynomat installed in the floorpan and in the passthrough area between the cockpit and the trunk. Any (non sarcastic) suggestions?

I'd suggest a Magnaflow muffler of the appropriate type. They are nice and quiet yet still flow well.

Resonator?

What type would that be?

Not sure. I think Ben would know more or maybe you could look it up.
I just know they are allot quieter than most mufflers and flow just as well.

I only have a straight pipe with a Borla muffler and my friends make fun of me because of how quiet it is. I tried adding a resonator to my civic and it didn't do much. I switched to an oem header and added a old performance cat and now its tolerable. I'd switch mufflers if I were you. Should be easy enough if it is clamped on right now.

I've probably got the quietest turbo miata. Im obviously sacrificing some power but it's a trade-off I'm willing to live with.

I would get one of these if they weren't so damn expensive. Maybe I can make one? Hmmmm

Just pop a resonator in the catback. Fast, cheap, effective.

I have a custom Magnaflow catback that was lound and lots of fun at first. It got tiring in a hurry. I went back to the shop, installed a resonator, problem fixed.

damn- I've got the exact same exhaust in a 3" version. Cheap bastard! :gay: Yes, I've received numerous comments on just how quiet the car is. I think the biggest risk you run using these cheap mufflers are broken welds leading to rattles. I hope to check just how much of a power loss the "turbo" muffler is causing at the next dyno since I've got a flange right in front of it.

I have 2.5" pipe with a 18" resonator and it really isnt that loud.

SO I think adding a resonator will do it.

If not and you want to go way budget the summit turbo mufflers are legit. I have gone that route on cars I Track. I have them flanged so I can take it on and off for track days and street time

I've had a summit racing turbo muffler on my altima for years. i wouldn't actually put it on a turboed car however, it will impede performance.

no doubt but it's crazy quiet. Id like to buy (or make) one of those virtual exhausts and put it on a solenoid so I can choose to have it open when I hit, say 5psi or so.

like have it boost actuated, like normal but be able to choose whether or not it opens in the first place. I bet I could do it with an old throttle body. Gotta see how much space I got for that though.

you couldn't hear my 2.25" borla dual exhaust.... stock was louder.

That and blowing the stuffing out of the inside eventually.

would this take the place of my current muffler or is this an inline install in the midpipe? That performancepeddler site has them for a little over $50. Not too bad.

If this does replace my current muffler, I assume I am going to have a muffler shop make a flange so it can fit to the midpipe?

When you guys say loud, is that just plain noisy all the time?

What I want in an exhaust is noisy when accelerating hard, but quiet on the highway. Possible?

Edit: I think I want that awesome exhaust cutout.

nah fit it on the midpipe.
