The modeled after the iconic Quad-Tip Exhaust system for the Acura TL-S. Using that influence, we developed this unique, fully custom built exhaust tuned just for the 2009-14 Acura TL SH-AWD (3.7L model, both automatic and manual transmission variants).

The ATLP Quad-Tip Performance Exhaust exhaust emits a subtle and smooth tone while cruising, and a deep authoritative roar at full throttle. The J-series engine, especially the AT models, are notorious for drone, and the lack of low end throttle response. ATLP tuned the Quad-Tip system to keep drone at a minimum, while also improving throttle response. This updated second version (V2) of the iconic ATLP Quad system for SH-AWD 4th generation TL models answers customers' needs for a system that has milder interior sound free from resonation and drone, while still emitting a smooth, throaty, aggressive tone that compliments the TL's sporting nature without drawing unwanted attention. Mid-range and top end power was increased. The results satisfy, and exceeded our expectations.

Exhaust bolts on to the third cat and runs at 3 inches, and splits off into a dual 2.25 inch diameter rear section that directly feeds into the mufflers. We were able to increase flow, while keeping throttle response peppy and lag-free.

Muffler Features

  • Four 4" 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 2009-2014 Acura TL SH-AWD (Auto/6MT)

Customer Questions


Can this SH-AWD exhaust work on the Base 3.5L model TL motor, If you Install the SH-AWD j pipe. Reason is i would like the larger diameter mid pipe used on the SH model for my 3.5L.


This system is not designed for a FWD TL. We could not comment on the degree of customization needed to get it on. It is possible that a 3" FWD version could be offered in the future.


What is the expected power and torque gain? The car is 305 HP and 273 lb/ft.


This system provides a power gain of approximately 5-8 ft-lbs throughout the rev range, and roughly 8-10 hp.


Will this system pass a smoke check or emissions inspection?


Yes, this system does not effect emissions in any way.




This system is not known for being particularly loud, however it is audible from within the car. A resonator will reduce the interior sound of the system.


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.

Q:What is the expected difference in loudness, overall sound, and performance between using this exhaust with and without an aftermarket performance J-pipe like the RV6 or XLR8 J-pipes?

The j-pipe and 3rd cat deletes do not change the loudness of the exhaust remarkably. Mostly you will get a little different tone...a little more grumbly. But not really louder.

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.

  • Love this exhaust! January, 11
    By Gabe F, Spirited/Stylish Commuter
    I am very happy to have gone with this resonated system! I am very pleased and impressed with overall quality and fitment of the system. Sound wise the system is very impressive. It had a very nice deep growl as I wanted when driving aggressively, and it is as quiet and deep sounding as I wanted for everyday normal driving. Thank you Heeltoe for this excellent system!!
