My 4" maggie was MUCH quieter than I expected...

Mine wasnt 4", but my MAC midlengths, 3" ORY, and Magnaflow catback was surprisngly REALLY quite. And it would get decently loud at WOT, but it wasnt enough for me, so thats when I got the E-cutout. Best decision I ever made. I can close it and be super stealth, or open it and make a billion alarms go off.

Also, on a side note, if anyone cares. When I was dynoing my car, I did a pull with cutout open and closed, and with it closed I lost 68rwhp. So if that convinces anyone with turbo the importance of a freeflowing exhaust system.

I had a qtp e cutout. It doesn't hold up good at all. Maybe a dmh would be better?

Magnaflow 14161 here, its a 3.5 in/out 6" round. I have 3.5" single to behind the rear wheel. Im really happy with the sound, a nice rumble with very little resonance. Also running a E cutout.

whats a muffler?

Find a slp dual/dual catback or just the muffler to replace what youve got and retain the cutout. They flow pretty good for a quiet muffler. You can wire the cutout to something either rpm or boost activated to open/close it if you get creative. I really don't think you're going to find anything that stealthy thats free flowing.

Im building a new exhaust for my car now just waitin on a vband flange, its 4" from the turbo and i have a 4" magnaflow muffler that you can see straight through with a dump right before the axle.

U think this system is gonna be restrictive, i didnt plan on putting in a cutout
I have a 370 with a pt88
I had open downpipe b4 and not looking to lose any power lol

I have the same combo and first tried it dumped up front under the hood. That was about as loud as my old 402 with dual 3" XR1's dumped before the axles. Then I went to a 4" mandrel to the single 4" magnaflow dumped before the axle.

That quieted things down alot but I am a big fan of stealth and that just wasn't quiet enough. So I had my exhaust guy take the 4" over the axle and split into a single 4" with a flange and a plate on the passenger side and a 3" with a single Xr1 going to the drivers side. So for street duty and low boost (12psi), I cap the 4" side and run all the exhaust thru both mufflers out the driver's side rear.

Thats the same muffler I had cobra killer. I switched to dual 3" magnaflows and to be honest its a little too quiet now...

No such thing as too quiet. I wish mine made no sound at all. Like a Lexus. When hunting predators, it's best to sound like prey.
