rt high flow cat initial impressions
well, i finally buckled down and bought a rt cat because i couldn't find a good price on a 06/07 oem unit. anyways, the butt dyno tells me i got a couple more ponies lurking under my hood. as an added bonus, throttle response seems to be just a fraction better! the noise under normal conditions isn't bad at all, even at idle. however, at WOT (wide open throttle) that thing is waaaaaay to loud for my taste. additionally (only at wot) i've noticed a significant amount of resonance inside my vehicle. i'll head to napa to pick up another gasket (part # 31369) to see if that has anything to do with it. i have not installed the anti-fouler and don't plan on it, unless CELs start to pop up. overall, the mod is a good value if you can stand the increased volume both in and outside your car. check my sig for accompanying mods.

interesting man..... What prices were you getting for the oem 06/07 cat? The best I've been getting is from acuraoemparts.com or oemacuraparts.com, for $535 and 570. How much did you pay for the RT?
Even though the extra power is good, I think that the added throttle response would benefit us 5AT owners.

^ your absolutely correct about the the auto and throttle response. i payed $320 for the cat at a local shop - price includes tax and shipping. as for the oem unit, about $550. hondata will probably be the last of my performance mods and then it's time to address the a/v system

^^thanks for the info. I'd most interested to see if you get CELs anytime after a couple of WOT runs.
I'm now also wondering if the '06 OEM cat would also get CELs. I really have no idea what paramters the 02 sensors read as normal, but I would imagine that the 06 sensors might be set up differently than an 05.

The CEL will only pop up if I'm driving on highway (100km/h+) with stable light-footed low rpm range (2000-3000rpm) over 30mins, and it's gaurantee too. haha
BTW: I don't have a RT Cat, I have the Magnaflow Cat, so it might be a lil different.

Oh yeah, enjoy that "new cat smell" ![ugh](https://acurazine.com/forums/images/smilies/ugh.gif)
That was the worst side effect of any mod I've done to the TSX so far. I was double checking it for 2 days until it went away.

Update: it's been a couple weeks now and smell is gone, as well as some of the resonance inside the vehicle. i installed the napa gaskets as well, so it seems as if they've helped a bit. NO CEL YET

Don't mean to hi-jack the thread. What do you guys think about the random-cat w/ the stock 04 exhaust? I've searched the threads and couldn't find anybody running this specific setup. Maybe I should be the guinea pig.

Its only loud unless you are at WOT and its a nice whine/buzz noise.
GOes well with my icebox, comptech headers and pulleys. Not interested in any aftermarket exhaust system.

bringing this thing back to life courtesy of carbongrayearl. haven't experienced any CELs since the install. the decibal level has definitely gone up a bit with the cat, but it's bearable. however, the older i get, the more i seem to notice it

It may even pass visual inspection with the cat heat shield on.

thread revival: i ditched the rt cat for a carsound/magnaflow unit. this was my 2nd rt cat (first one slightly damaged from an accident). i had to re-weld one of the flanges on because there was a leak
also, i'm unsure y this cat is designed with different in/outlet piping diameters. the carsound unit is symmetrical and has dyno proven gains
