Customer Questions


Hey, what gives? I ordered a non-resonated system and what I got has what appears to be a round muffler-looking thing in the mid looks like a resonator! Explain?


That is technically NOT a resonator. It is a PRT chamber (Purge Resonance Technology) which is built into the system to make it less noisy inside the cabin. We have more on this part published here: XLR8 Performance Exhaust: Non-Resonated System Has A Resonator In It?


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.


Does this xlr8 catback exhaust system include the j pipe


The J-pipe is a pipe in front of the 3rd converter on the car. A "cat-back" is a system that is all after the converters. Therefore, no a cat-back would not include a j-pipe. We do offer j-pipes as separate items though!


What is the horse power gain with this exhaust.


You might expect a 5-8 hp increase with this exhausts. That is pretty typical of most cat-backs for this car.


Is the system bolt ons or there are some welding parts


This is a complete bolt-on system with all hardware needed included. It is a driveway job!

Q:Will this work with the v3 jpipe?

Yes this exhaust will work with any of the popular j-pipe options for the TL.

  • XLR8 EXHAUST AND XLR8 J PIPE October, 19
    By armando inoa, Grocery Getter
    Sounds great on my 08 TL. Would recommend to any other TL owner out there that's looking for an exhaust that's not too loud but sounds decent. Kinda like a low tone growling lion. Just like Hyder said^, in the cabin it sounds like a bunch of monks humming.
  • very nice May, 18
