Ok, looks like we are just about good to go here. I need to get the original car back for testing of a final component...we need to add a couple flex-pipes into the system. So once we get Dope26070 back in here the total cost will be finalized and we can get cracking.

Hello Mr.MrHeeltoe
I'm in San Clemente, CA which isn't far at all from Mission Viejo and would be more than happy to loan you my 05 RL for test fitting. Please PM me to setup a date/time.
Thanks

Be sure to do some before & after inside/outside videos of exhaust note.
Maybe an inside 0-60 run before & after, plus standard outside start car, idle for ten secs, a couple revs to 4k, a couple revs to 6.5k
Honestly getting the numbers on the dyno counts about 50% of the way to making a sale. The other 50% (or some combination of both) is an exhaust note that doesn't sound like a ricer 1.3L squeeking out a tight high pitched mega fart.
A good dyno result will get people interested, a good exhaust note will get people to spend money.

I am in the midst of scheduling another test car to come in so we can put some final nails in this project.
I am examining the pic on page 5 and some of the comments made...
I am sorta wondering if this design is really the best idea. We know we can get 10-15 hp on the other acuras just from a J-pipe and cat-delete. Also, given the fact that even those who want sound are not going to want to suffer with drone. So, I know Mike had done the R&D on this kit, but it sounds like the dynos kinda need to be tossed out because of the non-awd nature of the test. I am thinking that we could have a nice product line of just a j-pipe, optional cat-delete, and then a set of bolt-on muffler axle-backs for a little more sound and a nice look. Whole kit would be like $1300-1500 I guess. $450 for a j-pipe and maybe $135 for a cat delete, $600-700 for the mufflers (just kinda guessing...)
What do you think about changing direction here? The part Mike made certainly looks cool, but I can't help but think most people will value the looks and sound of mufflers and the performance of a J-pipe that has the option of keeping the stock cat in place. I almost feel like we are going to make this mid pipe and lose people who want a stock cat option and then have more people asking for mufflers.
If we keep the stock middle pipe in place, there is an almost guarantee the sound will be just right with a minimal compromise in power... In short, if you want power, you can get it from a j-pipe and cat delete. If you want sound, you can get a nicer tone with new mufflers. The middle pipe would be a big advantage to higher modded cars...but that does not really speak to the RL demographic.
Thoughts?

I think having all those options is a great idea, as for broke people like me we can buy a piece at a time or and if you sell a package deal. Please check for clearance as my stock piping scraps. I am fully lowered on teins.

That was another thing...the wrap-around cross-over design of the j-pipe on the prototype has been known to cause some issues with ground clearance. Going with a design closer to the 3rd gen TL V2 J-pipe might actually provide the added benefit of less scraping with little or no compromise in power.
I guess what I am saying is, I am seeing you guys as being more of the "add power, sound cool, but don't f- up my RL" crowd rather than the "gimmie all the power and a sick looking part, and I can compromise on drone and comfort in the name of fashion."

I would certainly appreciate a no or less drone option. What are the performance gains of the cat-deletes versus increased sound and emissions? I think the more options there are, the better. Will there be any sound difference from just the J-Pipe?

Pre-cat deletes, from what I hear, have quite an impact on sounds. I would leave those alone, but then again that isn't what we are discussing here.
The 3rd car below the car is not going to have a big impact on sound, that is mostly a power mod. Same with the J-pipe...it makes the tone slightly more aggressive but if you never drove an RL you would probably never know there were any mods on it if all you had was a J-pipe and race pipe (3rd cat delete). Although it would feel a bit faster than the next RL...
The noise comes from deleting the stock resonators.

Don't think my RL would pass emissions test without a cat.
I think it would be safe to say more buy RL's for the luxury factor then the "drop it to the ground, replace the springs with bricks, and put straight throughs on" crowd that goes for a TSX/TL.

You are talking about the third cat in the pipes right? The one after the merger or the two pipes into the J-Pipe. Do you have an idea of what the assumed gains are of removing this cat compared to the J-Pipe alone. The other question was, will removing this cat cause a big jump in emissions? There has been talk earlier in this thread that even touching a factory installed cat will cause you to fail an inspection if the person takes the time to look.

if i bought a j-pipe i would certainly rather buy one that allows me to use my factory cat. especially so I could just pop my cat back in for inspection, then replace it with a bolt in straight pipe for the rest of the year.

I never mentioned anything about a pre-cat delete. You said,

You said "cat deletes" like you were saying delete all the cats. Deleting the 3rd cat we have seen on TLs take a J-pipe gains from 10-12 up to the 13-18 range. It doesn't sound like a lot more, but really it makes a significant difference.
There should not be a big jump in emissions, no. And we know many customers are able to pass smog without it in some states. That does not make it legal to remove it though so we offer it as a Race or off-road part only. That being said, our converter replacements keep the heat shields in place so as not to make the cat-delete obvious for visual inspections.
Ok, so it is soundling like my proposal is not such a bad idea provided we can show the gains on a dyno. I think the costs will also stay in check with this part and provide options for people looking to keep the car quiet and smog legal. For those looking for more sound, we can do paired muffler sections to add distinctive ATLP looks and tones. Who knows...maybe one day a middle section will make sense. Right now, to me, it doesn't.

Thank you for the good info. Looking forward to the dyno results. Although I don't look forward to hearing about our stock 200 whp again.

I'm down for a Jpipe and 3rd cat delete option only.
I really don't give an F about the dyno results. The fact is the part(jpipe) WILL make power. Don't care about the having to retain the 3rd cat either. Here in MD, if you have no CEL you pass emissions. No visual inspection either.

No updates at the moment. We were just about to start/finish the SH-AWD TL system today when we got word that our fabricator's dad was rushed to the hospital. Things are paused atm...this stuff is taking a while, I know.
T-jay, we may ultimately complete the system, but we will be doing it in sections.
