The Original Quad-Exhaust system for the TL-S! While already special in this sense, we partnered with Stromung Exhaust Engineering to create a unique, fully custom built exhaust tuned just for the 3.5 TL-S.

We were able to create an exhaust that emits a subtle and smooth tone while cruising, but a deep authoritative roar at full throttle. The UA7 engine, especially the AT models are notorious for drone, and the lack of low end throttle response. This cat-back is tuned the to keep drone at a minimum, while also improving throttle response. Mid-range and top end power was increased. The results satisfy, and exceeded my expectations.

Exhaust bolts on to the third cat and runs at 2.5 inches, and splits off into a 2.25"" diameter that directly feeds into the mufflers. We were able to increase flow, while keeping throttle response peppy and lag-free.



  • - Four 3.5h polished 2-Piece tips shows the attention to detail.
  • - Staggered offset accents the body line, with or without the A-spec kit.
  • - A matte finished face and hi-polished canister gives the entire exhaust a distinct look.
  • - TIG welded seams.


  • - Fits 2007-08 Acura TL-S (Auto/6MT)
  • - Fits 2004-2008 Base TL (Auto/6MT)*
  • - *Bumper must be fitted with a Type-S spec  required.

Customer Questions


How much softer is the resonated? I want something louder than the stock, but not a lot of drone. Should i get the resonated or non-resonated?


The exhaust without a resonator will have an increased sound over stock, but will also increase the cabin noise. To reduce this to a minimum the resonator is the best thing you can do. The system doesn't drone a lot without one, and we have had people say they thought the system was too quiet with one. But if you are concerned it may be best to just get one since it won't change the sound out the tips much at all and it will be less prone to drone.


I want to do from the header all the way back . Do you have a header that fits to the j-pipe, then exhaust?


Your vehicle is not be equipped with traditional "headers." Before going further, we would suggest reading this article regarding the exhaust layout on your J-Series Engine equipped vehicle: An Outline Of The Exhaust Layout On J-Series Honda V6 Engines

We can provide a complete set of exhaust components from the engine to the tips, and will be happy to consult you on the needed items.




Yes, it is.


If I get the 3 inch exhaust is it going to be louder?

Note that this system is a 2.5" system. The 3" V2-R is available here: ATLP V2-R Quad-tip 3" Performance Cat-Exhaust System, 2004-08 Acura TL & TL-S


We are not sure if you mean louder than stock, or louder than a 2.5" system. While it will definitely be louder than stock, it is not a lot louder than a 2.5" ATLP quad cat-back would be.

Note that this system is a 2.5" system. The 3" V2-R is available here: ATLP V2-R Quad-tip 3" Performance Cat-Exhaust System, 2004-08 Acura TL & TL-S


Is the 3 inch exhaust going to have clearance issues are on my type S TL?


We have designed the ATLP V2-R 3" system to fit the vehicle without interference and excellent ground clearance. No clearance issues should exist.

Q:Can i fit this on a 06 with a Aspec kit really don't want to change to a type s bumper ??

The A-Spec kit for a base will not accommodate the tips on this system. You'd need to change to an A-Spec lip for a TL-S model. You would not need to get a complete Type-S rear bumper.

Q:I currently have excelerate v2 j pipe. Will I run into problems installing atlp resonated catback system. Do you have a picture or video of the catback resonated system. I don't want any droneing sound in the cabin. All new resonated system comes with larger magnaflow resonator. Will my excelerate v2 j pipe cause some droning with atlp exhaust. Thanks..

No the ATLP system will fit perfectly fine with the XLR8 J-pipe, and no the j-pipe will not cause a drone. We've got some videos of the ATLP and XLR8 systems on our YouTube channel. You won't really hear much difference between a resonated and a non-resonated system in the videos though. The drone will be a lot less with a resonator, but a video does not show that well.

The ATLP systems now come with our own ATLP resonators which have been more effective at reducing drone than the Magnaflow ones.

Q:What resonator is used in the resonated ATLP systems?

A hand-made ATLP resonator is used on ATLP exhaust systems. The non-resonated systems do not come with resonators.

Q:Hello I have this exhaust system and I would like to know if I am able to remove the resonator or is it not removable?

The resonator could be removed by cutting it out and welding in a straight tube in it's place.
