I have 7th Gen V6 sedan.
I used to have Magnaflow cat-back but it was a little TOO loud and when cruising highway, it was very very annoying.
So I went back to stock and Magnaflow is just sitting in my house...
Does anyone tried or have anything else?
how about the one from Mugen?
Can you even get it in US, and if you can how much and how's the sound?
And 03-05 sedans have bent tip so you can't really see the exhaust...someone asked why I took my exhaust off when I had magnaflow...cuz they couldn't see and it was loud...haha
Can you use ones for coupe if I get the bumper cut or put aftermarket bumper?
Are they the same size and everything except the tips?
p.s. let me know if anyone is interested buying magnaflow for your V6 sedan...
It sounds awesome, only thing I hated was that I had to hear the constant noise while cruizing70~75mph...somewhere between 2000rpm and 3000rpm is the loudest...you pass that, CAI takes over...so it was quieter going 80mph and over...

Well I've enjoyed my GReddy SP2.
It's not too loud, and when I cruise at 2000-3000 rpm it's just a small rumble in the back; something you can overlook easily. Give it gas and you'll hear it growl up some, but nothing too loud or raspy.
My CAI is louder than my catback easily.

I have a WS2 setup. I got it because it was the quietest performance exhaust that I could find. It is very similar in design to the SP2. What model did you have that was too loud?

Does Greddy make one for 03-05 V6 Sedan?
There were only a couple I could find for V6 Sedan (with bent down tips)
The Magnaflow cat-back I have doesn't really have a name I think...they only make one for Accord V6 Sedan.

if the magnaflow was too loud, stay away from the EVO2 ...... the SP2 will be quieter

klrspz, thanks for the post.
but there isn't one for the 7th gen v6...
maybe i should get custom pipes?
could I keep the magnaflow mid-pipe and maybe put the SP2 mufflers???

ive been thinking of ways to reduce the cabin noise with my exhaust...Falkore do you have experience putting a glasspack in where the reso or pre-muff was? Ive thought of this but havent heard of anyone saying that it would help reduce the cabin noise....I have the magnaflows too, but custom piping..I dont think its too loud on the outside, just in the cabin....

I agree with bssmagik83.
it's not too loud outside but in the cabin...haha
so glasspack is supposed to reduce cabin noise?
and in the description from that website, it says it should placed at the end of exhaust at the end of the car...
so if you put one in midpipe, will it still work???

I don't have experiance with the spiral thingy .... it just looked like a design that could work. I wouldn't replace the resonator with a glasspack, rather add it in line. The resonator is tuned to the engine and it should remain to avoid backpressure bubbling when you let off the gas. The cabin noise is a tricky thing. Most of it is generated by the resonator. I'd expect that a glasspack upstream of it would help, but I really can't be sure as I haven't seen the installation. The theory is that the glasspack would smooth out the flow a bit before it reaches the resonator leaving less energy in the exhaust stream to produce the puffing that causes high and low pressure waves that generate sound. Like I said, I'd expect it to work, but can't say for sure. The spiral thing should act similarly except that has vanes that will cause a spiraling effect which would allow the center to flow much faster than at the walls. This variance in flow rates would cause evening out of the total volume of flow to reduce noise by the same principle. I'd expect the glasspack to work better since it is a larger plenum than the pipe; the spiral thing will cause an increase in backpressure, which may or may not be as or more effective. I'd prefer the glasspack install.
