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:I have a 04 Acura TL 3.2 4 door will this fit the 4 door? new to the Acura so I don't know much ab them
A:Yes sir, actually all the TLs are four-doors and this kit will bolt up perfectly. Although the tip cutouts in the bumper are not going to be wide enough for the stock tips. You'll need to install a Type-S A-Spec rear lip to install this exhaust.

Will the atlp v2 quad tip exhaust system fit a 03 cl type s


No it will not.

Q:I have a 2005 TL 6MT with the a-spec kit; will this fit my a-spec bumper?

It will only fit if the A-Spec lip is a TL-S spec. For a Base A-Spec lip, the tips will not fit in the bumper cutout.

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:What is the decible they produce?? I want a exhaust that isnt stock but is more quiet. I have the Greddy Evo2 catback now, and wanting something more chill sounding.

We have not published decibel ratings for this system. It does not sound stock but it is much more refined sounding than the more aggressive systems from Greddy and XLR8. It is a smoother tone that will drone less and draw less attention, but you will still get many compliments!

Q:Which is louder? resonated or non resonated.

Both systems sound basically the same, although a resonator will make the system quieter INSIDE the car. It is designed to reduce drone, or resonation, in the cabin. It is especially helpful on auto-trans cars.

Q:If I have purchased all the parts up to the cat back. And the j pipe it's 3 inch ,then is not going down in diameter a bad thing as this cat back is only 2.5 inch ?
A:No, it is not a bad thing. That's totally fine. You will just have the reduced performance of a 2.5" compared to a 3" that would have a little more performance.

    I've had this exhaust on for a couple of months now & its safe to say I do not even have one ounce of regret. The system makes the J35 come to life and really delivers a nice deep tone at idle and low rpms. No issues with drone for me without the resonator either!
  • Aggressive sound May, 14
    By Erik Santiago, Grocery Getter
    Bolted right up and fit perfect. Sound is very low and aggressive with no rasp.
  • Perfect! May, 6
    By daniel xaysongkham, Spirited/Stylish Commuter
    Definitely a perfect fit and what I needed to complete my Type S conversion. Thank you Marcus! Plan on doing business with you for awhile
  • Superb product August, 6
    By Jordan, Street Performance Enthusiast
    Took 4 months to get due to group buy on Acurazine but well worth the wait. Perfect sound, good gains. - I got non-resonated version and have RV6 j-pipe and HFPC's and with this exhaust the note sounds like a stock E46 M3.

    Extremely loud at WOT if you are non-resonated with supporting exhaust mods - no drone though. Could not be happier with the product.

    My favorite part is the nice low growl when accelerating at low RPM's that lets you know there's some work done to the car, but it's not overpowering to the ears.
  • Wow Amazing!! September, 6
    By Travis Hood (Bubz), Street Performance Enthusiast
    Super fast shipping!! Installed it myself and everything went together great! All the welds were amazing. Sound Quality is great! Took about 2 days to get broken in. But sounds good. Thanks ATLP!
