Here is the first of many products under our brand XLR8 for the 4the gen TL. The XLR8 test pipe which is a cat delete for the third cat which includes tabs for the heat shield is now in stock and ready to ship. This pipe is made out of T304 stainless steel with a 2.5" IN/OUT with heat shield tabs. It comes with all the hardware needed and gaskets for both sides. Soon, we will have the high flow cat available and the AWD prototype j-pipe is on the way to us now.

These are ready to ship!!

Correct me if I'm wrong. But you would need the high flow cat instead of this if you want to pass any state that does emissions testing right? This probably wouldn't pass MA inspection...

Lucky AWD guys!!!. So this wont fit the FWD at all? Do you know the hp/tq increases?

HFC and J-Pipe!! Ok just a few more weeks hopefully..

This thread must have slipped under my nose just like everyone else who didn't reply. This is exciting news, but the J-Pipe is the most exciting news yet, I simply can't wait!

Excelerate, would you mind giving us some preliminary pricing on the J-Pipe? We need to know how much money to save up! haha.

Also, I'm curious as to if the test pipe was tested and if it threw any sort of codes. If so, how do we correct them?

Nice! Glad to see something finally came out of my parts being sent over a year late. ;] It looks like a quality piece, but I'm personally waiting for the resonated version.

This will not throw any codes, all of the oxygen sensors are BEFORE the J-pipe, so no worries!

CleanCL, you've made my day! I would imagine this would increase noise output if I installed it, so maybe I'll hold out for the hi-flow cat instead... I just hope it doesn't go over $250, but I have a feeling it will.

im pretty sure you will still pass the emissions test. even tho i have a 3G, i have a test pipe as well and passed emissions just fine witht he 3rd cat removed. you defintely wont pass if you remove the primary cats

The j-pipe will be in the $450 range. This is a delete for the third cat; the oxygen sensors are in the pre-cats. This will not cause any CELs.

The high flow cat will be about $300. It will be full T304 stainless steel with heat shield tabs and a 200 cell high flow cat with metallic substrate.

Thanks again for the parts; I'm finally getting them to get these parts done. I'll be calling you soon. They are sending me a prototype j-pipe to test fitment before putting these into production.

We won't be doing a resonated test pipe. We will offer a test pipe or a high flow cat.

One more question (annoying, I know). I looked up the 3rd Cat on Acura's EStore, just to certify it didn't have any O2 sensors down there and while looking at it, I noticed the gaskets the exhaust system uses are metal rings.

I know from past experiences with 4-cylinder DC Sports Header(s) that they come with ring gaskets, which are supperior to the aluminized fiberglass gaskets as shown in the Excelerate Kit.

My question is twofold:

1.) Does the Excelerate cat.-delete test pipe have the ability to utilize the stock ring gaskets?

2.) If not, are the gaskets that come with it of high enough quality to withstand years of abuse?

I ask this because I had Megan Racing Header(s) on my Prelude at one point and they use the aluminized fiberglass gaskets that died out in 2 months. I even coated them with permatex copper spray just to ensure a good seal! When removing the headers, it was clear that the excess heat of the exhaust system had steadily burnt into the gaskets and it travelled all the way until the holes went straight through.

1. No
2. Yes

Megan is garbage. Their parts are garbage. We use high quality gaskets.

Look what just arrived!!! This is the prototype j-pipe for the 09 TL AWD. CleanCL should be down soon for test fitment and then these will go into production.

*jiiiizzzzzz*

Looking forward to the j-pipe and a high flow cat!

will there be a big sound difference between this and the high flow cats?

i will be getting a j pipe as well. just want my car to sound better and pick up some power

how did i miss this thread?

I would be the first to send my $$, if i wasn't in the middle of buying a home.

Saw the J-Pipe in person today--wanted to grab it and run out the door. Once there's some early adopters with some opinions, I'll probably go for it along with a high-flow cat if I can swing it...

Unfortunately the test fitment for the j-pipe did not go well on my car. It just needs a few tweaks, but someone please go to Arizona before I plan a cross country trip.

On a better note, we did install the test pipe. It fit perfectly, and the stock heat shields fit the tabs perfectly as well. From a sound level, it goes almost unnoticed. There is a bit more tone to the exhaust at low RPMs if that makes any sense. Maybe a bit more growl. At cruising speeds, zero drone, zero cabin intrusion. I was worried and was going to get the hi-flow cat, but I see no point! Also, Josh and I noticed the inlet is 2.5" but the outlet is more like 3" to mate to the bigger catback section of the car. In terms of performance, with no dyno it's hard to quantify a number so I refrain from saying anything to that effect, but the higher end RPM and throttle response feels a bit more 'free' with NO low end loss.

since the design of the jpipe looks similar to that of the 3g, will their be clearance issues for those lowered more than 2"?

More than 2" it is possible you may have clearance issues. We will check clearance of the j-pipe and take pics once we get one installed.

Im so suped for the j-pipe and high flow cat when it is finally tweaked out correctly to fit and all tests are Good. Keep up the good work

i'm confused where this goes exactly.

we have the primary cats in the block,

then we have jpipe

where the hell are the 3rd cats?
Is this it?

yes, that is it;

Cat is closest followed by dual resonators and finally mufflers at the end in to the tips (I believe).

anybody order this yet? reviews? i'm dying here, i want the full exhaust now, would the local acura dealer lend you a car?

I don't think this as been asked yet.... but what would be the difference between getting the test pipe vs. the high flow cat.

Pros and Cons of each anyone?

The test pipe eliminates the cat. The high flow cat keeps a high flow cat in place for emissions purposes and to reduce the smell you get from having no cat. You still will have 2 primary cats so the smell won't be that bad but you may get some smell. Keep in mind a good high flow cat will only cause you to lose about 1 hp over a test pipe so the HP factor shouldn't be an issue.

is there a diagram or pic of the primary cats? i'm curious how it's designed "in the block" and does that mean no aftermarket parts for that section?

any news on the j pipe?

nice stuff makes me wanna get a 4th Gen

nice stuff,

Is the j-pipe for the 09 TL AWD the same for a 2010 TL SH-AWD 6MT ?

IMHO they should. They share the same exhaust unless Acura changed something without warning anybody...

The big change for 2010 was the MT, not the exhaut system...

, YMMV!

Previous Acura models did sometimes change the j-pipe in the manual transmission model. This is because the transmission creates a different mounting 'situation' than the automatic. But I checked the parts websites, and every part from the j-pipe back is the same part number, so there should be no difference in this case.

Tadam! Her's the much more reliable answer!
