RV6 I4 PCD/Downpipe for the K24Z3 08+ Accord and 09+ TSX
#361
There is another guy on the tsx forum, Jeroplex who installed the same magnaflow mufflers, but with the CT-E mid muffler from their cat back system. I think it sounded great! Not overly loud, but had a good, deep tone. Granted that is with the stock downpipe though.
#362
this is going to be disappointing for you asian_candy, but i only have like 9 days left at home with my car, so if i cant schedule everything in a timely manner i may not end up getting to install the exhaust as quickly as i like.
that being said, i know where to get magnaflow stuff cheap online if/when anyone is ready to buy, and i will also do some TL research on this topic

Awesome info KillerG!!! So it seems i should install the magnaflow resonator between my RV6 HFC and the stock resonator?
The 12640 is a f'in beast! 6"X27"! I have the 6"X14". Guess I'm exchanging it. Will 27" resonator even fit there?
KillerG, what website do you recommend? I got all mine from Advance Auto.

Ok, i did some more research AZN, it seems like you can do one of two things: either replace the stock resonator with a larger one, or add on a second one.
This is a guess on my end, but I would add a second one. If your exhaust shop is chill, they should be able to work with you on it if its not what you expect when its done.
Looks like it should go in between like you said, and also you can get a smaller diameter if you are lowered and concerned about scraping,
I also use advance auto, if you look up there discount codes on retailmenot.com you can score some sweet sweet deals. Got both magnaflow mufflers shipped for 210, and if you add a resonator on it wont be much more (30-40) with coupons

I think I'll try adding a second resonator since it seems people had more success going that route. Right now I have a 6"X14", but since I am going an inch or so lower, I think I'll go with a 4" or 5" and measure the space between HFC and stock resonator to see what length would be good.
Hope you get yours installed in time KillerG.
#369
BTW, one guy on one of the TL links you posted had a white TL. I love the way his exhaust sounded!!
I believe he had a RV6 downpipe and either HFC, or was cat less. Had stock exhaust, but added a magnaflow resonator to kill the rasp from the downpipe.

I got a 20% off code for advance auto from some other coupon site, so use it anytime I order from advance.

Yes, everything from the HFC back is stock.... For now
@KillerG, yes I have the resonator already. I don't remember the part numbers, but I have 6"X14" magnaflow resonator, 2.5" inlet and outlet. 2 polished magnaflow mufflers, center/offset. 2.25" inlet/outlet. I also have 2 tips. Think they are 4" diameter, 7" long.
I basically copied Jeroplex's setup, but got a magnaflow resonator instead of the CT-E mid muffler.

you would definitely be right in stating that
, but the HFC is an expensive part and works well (gains wise) in tandem with the PCD. You gotta cut up the exhaust to get rid of PCD rasp anyway, so you might as well leave in the HFC and make the whole thing work while you are it
my 2 cents, but yeah, u right

Thanks KillerG. That is what I was thinking also.
I was debating about installing PCD but since I figured out that Asian Candy had the HFC also, that maybe by using the stock cat, I could keep the raspy-ness to a minimum. Kind of hit my budget limit on mods (just bought wheels and tires) so HFC and additional exhaust mods are not in the picture right now.... Will go with PCD and stock cat and will post my observations once I get it installed.

Honestly, what we need is someone like killer or anyone with an aftermarket exhaust to test this out...I really think, actually, I know, that the stock muffler / resonator combo is conducive to this raspy noise...it was the same case with nearly any other honda that runs a header on a stock cat-back. #truestory
#378
My exhaust guy suggested I lower my car before he does the exhaust. I was hoping to install my Coilovers this weekend, then exhaust following weekend. I'll be out of town for 2 weeks, for work, after that.
Doesn't look like my Coilovers will be here in time to install this weekend, so everything will be pushed back a week. Have to wait till I get back in town to do exhaust. So prob looking at a month or so dealing with the rasp

Just got my downpipe and testpipe installed. Man the gains are definitely noticeable ..i was grinning after my first little run on the highway. However, I totally understand what people are saying about the rasp. It is not like a nice G35 or 350Z rasp..its a more hollow sound than that. It is not my ideal sound right now but I definitely see potential for the car to sound good with maybe different mufflers or a custom cat back exhaust because I personally am not too big a fan of the typical "tight" honda 4 banger sound.

OK, here is an update in case anyone is interested.
I installed the RV-6 PCD and also put in an AEM CAI. Big fan of AEM Dryflow so for me, it was the obvious choice. However, this post is to provide more info about the PCD and possible rasp issues so will stick to that!
Installed the PCD but worried about rasp given all the posts. Sure enough, evil rasp. However, only really noticeable between 2-3k when accelerating as pointed out by previous posts. I have a 6MT so figured I could "drive around the rasp" by minimizing my time between 2-3k but after a week, found I was still annoyed by it. On the other hand, the power gains were truly noticeable! Car pulled harder to redline and a noticeable bump in mid-range torque. I had done something similar on my 08 TL (JPipe and CAI) and those 2 things just wake up Honda engines and let them breathe.
So, what to do? Loved the power, hated the rasp. The solution; get a second resonator (as also mentioned in previous posts, these forums are great!). However, in doing some checking, it seemed that the Magnaflows mentioned were too long for the area right behind the 2nd cat. Did some research and came across this: Vibrant 1141 2.5" Ultra Quiet Resonator. Only 14" long overall with a straight through design. $80 and 3 days later, I had it. Now, the real test, would it kill the rasp? The rest of the exhaust is totally stock, including the stock 2nd Cat.
Well, had it installed today and in one word; Abso-fn-lutely.... Rasp is gone, replaced by a nice mellow growl. So, got the performance gains and have a nice mellow sound and no more rasp! The performance gains of the RV-6 PCD are worth the price. But, if you are not a big fan of rasp, get a second resonator, get it installed and enjoy the benefits of the PCD!

I can tell you that before I added the resonator, I heard the exhaust all the time. Now, I hear the intake and a nice low growl in the background....
By the way, pic of the car...

However, I had a Vibrant exhaust on my Legacy GT and it had a great sound so I was already considering their resonator when the rasp issue came up. Either way, Vibrant FTW.

^the integrated header design is what's causing the rasp / sh*ty sound. Removing the cats completely will make the car louder, warranting further sound suppression. WS2 Muffliers, like what Ben has, are great at suppressing sound.
