I'm really happy with the top end though, It feels like it could keep on pulling beyond 7200rpm with ease. But being close to 100HP per litre at the crank leaves me pretty content until CT-Engineering gets their CARB approval for their supercharger.

Thanks

So I read through the forums here and decided the perforated resonator would be the best avenue to get rid of the rasp. I went to a local muffler shop and told them I wanted the longest one they had. So believe it or not I have a 24" cherry bomb resonator welded in about 3 inches after the straight pipe. Total cost was $120 and worth every penny. The difference was immeadiate and the car basically has a quiet normal sounding exhaust at all RPMs now.

So if RV6 is listening , I'd like to float the idea of having an additional secondary cat replacement option of a perforated resonator with flanges on each end in addition to their high flow cat and standard straight pipe choices.

Not at all, under normal boring driving conditions it sounds stock. Full throttle it is probably a bit louder maybe 1-2db and it sounds like a nice sporty Honda exhaust. But to be honest my intake pretty much over powers the exhaust anyway.

It has been discussed at length in the PCD threads, but it is likely due to the tightness (or lack of) of the defouler on the PCD.

Yea I threw codes a lot, pretty much all the time. it would go away after a couple of days then come right back. I just lived with it, but something happened when Hondata reflashed my ECU with the updated Honda/Acura image and it never came back. Then after the actual Hondata map and dyno tune it's still gone. So not sure what exactly happened, I'll just chalk it up to the newer ECU software version as the fix.

Lmao. Well honestly the smell isnt that bad. Just curious if I can pass emissions or would I need to put the stock header back on. Hope not though.

My 2011 TSX engine mods are as follows for anyone interested:
Full RV6 setup no cat with a 24" perforated resonator, only way I could get rid of the rasp.
Mobil1 0w-20
Air box resonator removed with a 4 or 5" PVC elbow from the bottom of the air box going into the wheel well to draw in cooler air. Search the forums as I posted pics of that setup.
Drop in K&N
Body and engine has about 7,500 miles on it, might see more power as the engine breaks in more.

I'm really happy with my tune. The car peaked out at 217whp which was quite a jump from the Hondata base map. Let me explain:

When I first went and tried to tune the TSX there was an issue with the ECU part number which you can read in the previous posts. So Church Automotive was only able to do a baseline run. When I wetn the first time the car put down 196WHP. That was with the Honda/Acura factory ECU mapping. I worked with Hondata and they were able to fix the issue with my ECU part number. I was unable to go back to the Dyno until a later time [today] but I did install/lock the flash pro to my car when I got home after the first attempt.

Fast forward to today, I arrived at church automotive and we did a new baseline and the power was down about 15 - 20 HP across the revs and was down around 20tq as well. I believe the first pull netted about 183WHP, I asked Sean[Dyno tuner] how come? He said it looks like the Hondata map needs more fuel. So he made some adjustments and within two runs he was back up to my original dyno pull at around 198WHP. Sean said he added some timing and lots of fuel to get it back up to our original amount. He then proceeded for about two hours and I believe about 25 pulls and said he thinks he has a good compromise with usable smooth power and peak HP, with a solid mid range. All said and done we hit 217.7WHP which is almost 20hp from the first baseline and almost 35hp from the first Hondata pull. Keep in mind this is a hub dyno and they tend to read closer to the crank HP than your more common roller dynos. I asked him what do you think the Engine is outputting...230HP? He said probably closer to 240hp. He said these engines are underrated from the factory.
,
If you don't know who Sean Church is, google his name he is arguably one of if not the best Honda tuners out there. So attached to this reply is his calibration for my car, feel free to try it out but keep in mind the mods I have and I was also running Cali 91 octane.

Here is a pic of the Dyno Chart. The Middle line is my original run about a month ago stock ECU. The bottom line is the Hondata basemap. The top Line is the Sean Church tune.

What did the dyno tune run you? I can't really find anyone by me who can tune. 1.5 hr drive to have the car tuned properly is worth the drive. I think my results should show a bigger increase than you saw. CT-Engineering icebox intake and custom exhaust. I'm looking at getting the rv-6 setup for my car as well. Any noticeable difference? They guys at Hondata recommended a high flow cat before I dyno it. Doug said to also throw on the CT Supercharger but I don't have 4k lying around right now unfortunately.
