Intake & Exhaust

3rd Gen Acura TL ATLP / XLR8 Exhaust Comparo Video

ATLP is a renowned brand in the Acura community for providing and exhaust with a look that is aggressive and timeless and a sound that is intoxicating without being overt. XLR8 is a staple of the Acura TL community as well, providing an exhaust that is crisp and clean looking but has the sound of a performance exotic. There are many videos online showing how each sound, but until now we know of no truly well-made video that compares the two back to back.

In this exclusive video, we bring the sounds of the ATLP and XLR8 Base and Quad systems to life in true HD sound, back to back on the same cars, for you to use to choose a system with confidence!

* Note, we have selected non-resonated systems for the sound test as the sounds will not be obviously changed with resonators, which are designed to reduce interior sound. Interior sound clips were taken but not used as they were nearly indiscernible from each other. The sound of both systems is apparent in both cars in normal driving, and the drone is minute. We realize drone and its impact on the livability of a system is a subjective balance. Heelote’s recommendation: If you want to hear the exhaust, don’t get a resonator. If you don’t want to hear it inside the car as much, get one. If you are not sure, don’t get one and weld one in later as needed.


2004-08 TL Front Camber Arms from Skunk2

UPDATE 6/11/10

We have just learned that the camber adjustment range of the Skunk 516-05-0004 kit on the 04-08 TL models is limited to 3-4 degrees positive and 1.1-1.2 degrees negative. For customers looking for more negative camber in the front, this kit must be modified in order to achieve the result. When you order this kit on there is an option for getting this modification done. Out of the box, we know the kit will correct negative camber you get from lowering the TL front end, but cannot provide adequate negative adjustment for extreme camber angles without modification.


Ok, so despite my previous professing about how a camber kit is not technically needed to prevent excessive tire wear, I have sold an unprecedented amount of them. Ingalls rear camber kits alone have moved more than enough units to support our WD program with Ingalls direct.

However, the front end of the 04-08 TL is not usually found far enough out of spec to warrant adjusting camber unless extreme lowering is performed. And in the case of extreme lowering, we find that the Ingalls retrofit adjustable ball joint, while effective, is a major pain to adjust, and does not provide enough clearance to the inner shock towers. This usually results in contact between said camber kit and inner shock tower!

Skunk2 has resolved this issue by releasing their ever-popular and much-refined camber adjustable upper arm for the TSX. As per usual, the TL got no love, but and Heeltoe Automotive has the exclusive scoop! This camber arm fits the 04-08 TL as well!

Check out the following pics to see the height difference between the stock, Ingalls, and Skunk2 ball joints.

Ingalls on the left, Skunk2 on the right (take note of the difference in adjustment and how much easier the Skunk2 kit is going to be to adjust after being installed on the car!)

So with Skunk2 the inner shock tower clearance issue is a thing of the past. Also, here is the part installed on a 04-08 TL:

Here are two pics showing the clearance to the wheels house at max and min camber settings:

Here are two pics KINDA showing the visual difference of the wheel hub orientation at max and min camber settings. The steering wheel is not turned, the car just has a toe impact when the camber changes. Just pay attention to the hub face and how it goes vertical when adjusted with the Skunk2 arms:
