Quietest Downpipe???
Hello all.
I'm looking for the quietest downpipe I can find. I have to replace mine as it was butchered before I bought the car and welded in front of the flange.
My choices are:
Stock
2.75"
3"
to run with a Tanabe Touring Medalion CBE and High Flow Cat I've already sourced.
I'd honestly go stock for noise, but I'm not thrilled with the super small stock size or the flat spots and restrictions. I figure while I'm changing it I might as well gain some power if I'm not putting on too much noise.
Chime in with your thoughts if you have changed downpipes and gotten louder or not gotten louder and the brand & size of your downpipe.
Thanks in advance!

I also have a catback + testpipe and when I ran a DP, the sound didn't really increase as much as I thought it would. In terms of a good downpipe for an EVO IX, make sure you get one that clears the ACD, as many of the ones available in the market are meant for the VIII's without ACD. My suggestion would be the megan downpipe 05/06 that is made to clear ACD, it's full stainless and fits like a glove on the IX's.

Also, how much increase would you say there was? How about in drone?
Thanks everyone for the input, I hope you can expand a little further.

FWIW, this is the 2.75 I was considering. At $80, the price is right, I think it would flow much better than stock, and be quieter than a 3". ebay downpipe
Considering that the Tanabe necks down slightly from what I have read to ~2.9" and I'm running a HFC that actually works (screen looking thing the length of the internals, looks like a hologram or something when looking through it)... I don't believe that 2.75 downpipe would be the restriction. I could be wrong though.

The Megan is not the same as the ebay one. I'm usually not a big promoter of Megan parts, but they have done their research on this piece. Due to many customer complaints on their 03/05 downpipe from guys with 05MR's and 06 IX's they completely redesigned their downpipe exclusively for the EVO's with ACD.
I had an HKS before, but ended up changing to the 05/06 Megan as the fitment was much better and the sound was more quiet. There isn't much drone over the stock DP and you can definitely feel the gains at highway speeds.

It is a downpipe afterall, not a part on your car that you should go completely baller on as it is just at steel pipe that no one sees at the end of the day

Are you gonna post these clips?
Does the Tanabe have some kind of resonator in the IP?
