Q: Does a quiet 3in exhaust (like Fujitsubo RM01A) have the ability to flow similar to HKS Carbon-Ti? Is it enough to match up to HKS 7460 GTII or FP Green? Have heard good things about it Fujitsubo, but wondering if it has a limited appeal to some people based on their setup.

 

I do not speak from personal experience with these two exhausts, but usually "quiet" means more bends, resonators, etc, which would mean less flow and less power. That being said, I personally do not think the catback section matters as much as say...the down pipe and turbo dump as far as power generation is concerned. As long as its 3 inch, I would say just go for the exhaust note you like better.

 

Muffler choice and piping material = sound.

Ti are always loud and raspy. Cobb and a few others are "quiet" and still flow as much as others. Ti has a weight advantage...but if not racing, wasted $.

Pure hp numbers and enjoying the sound of the car are different in my book. I go for good sound over some numbers. Of course, I now am over the standard Evo owner age range here...tastes for annoying might be different.

 

Just so you know, Fujitsubo is not a true 3" exhaust. It is quiet because of the taper inside the muffler and or resonators.

 

Prefer something semi-discrete up to about 2500 - 3000 RPMs, after that i'm more open minded

 

That's the heart of the matter...agree...otherwise maybe more of a no-brainer...

 

Another Question: Would a 80mm/3 Inch system fitted with Apex'i Active Tail Silencer (ATS) be a better option?

 

if you want quiet exhaust, stay stock or just get a catback and no downpipe/test pipe. if you want quiet exhaust except when in boost, get a wastegate actuated cutout. if you dont car how loud the car is, get a full catless 3"

 

Buschur tbe with high flow cat and magnaflow muffler is relatively quiet until you get on it. It's deep, but won't wake your neighbors up. And then it screams in boost.

 

I agree. I just installed the same Buschur setup and have driven about 600 miles with it and it is very mellow sounding if you drive a gear higher than usual. Pleasantly surprised how well it sounds on the highway. Of course under full boost and throttle it will get peoples attention. With uncorking the engine it has more off throttle torque making it nicer to drive slowly .... If that makes sense.
