hopefully this will help get more power out of the supercharger. I read somewhere here that in FI applications, the TL has a very restrictive J pipr or something of the nature. I would recoomemend getting abefore and after dyno of the the car.

Some N/A accord did and there one of the accord dynoed 252whp with other mod Im I think to custom a Jpipe too and try any gain or not either 2.25 or 2.5" piping

Congrats Ussi, this seems to be much better than the stock pipe but I'm not crazy about all those bends and the pipe seems small in diameter. ESP j-pipe looks a bit different but the concept is similar. Can't show you the pic though, since they didn't come out with the product yet.
My car is sporting the ESP one-off j-pipe at this time for my personal use and to a lesser degree for their testing of course. They did most of their testing on the Accord which shares our j-pipe and exhaust, they had a great success. The release of their j-pipe should be imminent since it's a great power-maker for a minimum buck, and that's what they are about. The gain in power, especially the low end is unbelievable. I believe that the outside piping diameter is 2.45in at most. But the most gain comes from eliminating the restrictive bends and crashed/narrow sections of the pipe. I'm not advertising for them or anything, I'm just telling you about my personal experience with this mod. Definitely worthwhile change to the restricted stock j-pipe.
Here is a pic of the factory TL j-pipe:
You can find my diameter measurements in the Type S j-pipe vs. regular j-pipe thread, do a search.
Can't wait to here about your experience and may be a dyno run, good luck!

^^Good info Actros.
For those who don't want to search here is what Actros posted about the stock J pipe
2 Inlets- 2" outer/ 1 3/4" inner diameter each
1 Outlet - 2 1/2" outer/2 3/8" inner diameter
I think my Jpipe is quite different from yours. Mine deletes the third cat so the "2" pipes are longer. When it was fabricated by Labree there weren't going to be bends, but they decided against that to keep them equa-length.
We'll see, I wish it wasn't such a freaking pain in the ass to get dyno'd otherwise I'd do a before and after. For now i'll just install it and do a before and after following my HBP install scheduled late next week.

Yeah the ESP pipe doesn't eliminate the 3rd cat so it is shorter than yours. I told them about making the pipe longer sans the cat but they were wary of the possible emission problems and possible CEL popping up. I don't know about that, but I didn't argue with them, I'm just happy that I got hooked up. Hopefully they will be willing to develop the "off road" version of their j-pipe in the future but for now...
I remember when I dyno ran my car with the new j-pipe the gain was a massive 20-25 lbs of torque more in the rpm range. The hp gain was less impressive but still significant 10-15 across the rpm range. Expect to see similar increase if not more since you won't have the restriction of the 3rd cat. Plus you're 6spd, the manual car always gains, revs faster and even sounds better, and in general adopts to mods better.
Man there is just a lot of variations with the AT car like mine, torque converter health has a lot to do with it.

I was going to get the J pipe you got, but decided to get this one instead because of the 3" outlet.
The J pipe I got is not equal-lengthed. Some say it would hurt performance, some say it doesn't matter. I guess we won't know until we try it out.
Can't wait to see your dyno to see how much we could gain by removing the super restrictive stock J pipe. Have you ever thought about removing the two precats as well?

^Yes FI and kicking, 320hp to the ground, baby! Those are surging horses though...not healthy
The HBP's high boost is slowing getting to me, the surging has become unbearable lately with the hot temps weather. I think I came to a point where the fuel management is crucial to the longevity of my car. Only there is no fuel management for our cars out there, besides the Greddy E-manage. Before I do anything else the fuel tuning is my main objective.

^Tell me about it man, more like a PMS or something, I wish there was a pill for that too. Honestly, to me it takes the fun out of driving the car, always needing to go WOT to avoid the surge.
Do you have anything in the works in regard to the fuel tuning. Oh I recall that you have the flash correct? Lookinco was trying out the E-manage but so far no news from him on that. I know for a fact that a couple of Accords already use that piggy-back successfully but I don't know anyone adopting it for the more complex TL.
Hondata is taking their sweet time, more like forever, last time I checked they removed the TL reflash info from their site, not a good sign, unless they made a mistake of putting it there initially. I mean c'mon, they have already flashed a lot of cars successfully, I wish I knew what's holding them from releasing the product.
Lookinco any updates E-manage?

j-pipe design is crucial. it's not as easy to design as it looks. thats where 90% of the backpressure is created. if you design it poorly, you will lose all backpressure. i think thats the main issue with the large j-pipe lookinco purchased, the rear cat has very little area to create backpressure, althought his car is much more modified than the TL it was previously on, so theres only one way to tell. p.s., you guys should send those to jethot, looks like the OP did.

Nice thread!
ussi you're doing big things with your TL and i commend you. Keep it up.
As for the EShift j-pipe release...hopefully it will be soon because from the looks of it the oem design looks like ass. You can just see the restrictive airflow.

ussi, def call me and let me know how the dyno went.

after i installed the greddy emanage ultimate, i must have gained another 30whp after tuning and eliminated the annoying surging problem. its funny how boomslang doesnt make a PnP harness for you TL guys, but have them for the 03 up accord v6's, it doesnt make much sense. i dont see how there is more demand as they say for accords then TL's? shoot, i had to throw on a SC kit for a TL cause they dont make a specific kit for my car.ive been sitting on my HBP for awhile now, but im waiting for some bigger injectors and a custom FMIC which will be done soon. hopefully it will turn out well

^^thanks for hooking up the pipe sean.
so i've been driving on this for only a day and all i can say it is a MUST have for those with blowers. i think this is the only mod where i've felt an increase in low-mid torque.
it also makes my exhaust sound nice except for a nasty rasp. . . looks like the midmuffler is def going back in.

Can you get rid of this bend to produce more power? I think it might make the exaust more restricitive...

ussi.... starting to get mad at you !!! j/k
where are the dynos?? with the P&P, Cams, new Pipes... you've been telling us all soon, soon soon.... i wanna know!!!
my guess... if your 6MT.....335whp? make us proud.
also, for Actros & ussi... have you contemplated some kind of boost cooler? methanol i believe they use?? not too sure about the details, but this car in general is a beast in the heat... i can only imagine a F/I TL....

i have been thinking about boost cooler for a while. 1) i'm worried about my cats and 2) i want to be able to tune it..

performance mods are,
comptech SC
eshift pro-cats
comptech catback
griffen custom radiator
greddy emanage ultimate (tuned)
boomslang PnP harness
4gauge pod set-up, all aem digital A/F, boost, oil temp, oil press
05 TL 6spd tranny (same gearing, but my accord 6spd had no LSD)
NRG torque dampener
tein ss-p w/EDFC + camber kits
f&b TL-S sway bars
19 racing hart r7 pro's 19x8
powerslots w/ hawk pads
HFP body kit
when i race, i use my BFG DR's 225/45/17 on my stock 6spd 17' wheels @ 22psi. that is the key ingredient on helping me get my 60fts in the 2.0's
