Available now at ECS.com!

The perfect way to unleash hidden horsepower in a modern turbocharged engine is to upgrade the restrictive factory catalytic converter and resonator with a smoother, higher flowing unit. This is a great way to increase performance and add a nice growl to the exhaust note. Ideal performance is achieved through expelling exhaust gasses at maximum velocity through a larger internal diameter and a less-restrictive 200 cell catalytic converter. We measured maximum gains of +27 WHP and +46 ft/lbs of torque on our Audi B8 A4 (when equipped with APR Stage 2 ECU software and ECS Luft-Technik Intake, FMIC and Charge Pipes, when flashed from Stage 1 to Stage 2 software and bolting on our downpipe with high flow cat).
Our ECS Tuning High Flow Cat and Downpipe offer impressive real world results. Get yours today and experience the difference!
**NOTE: Aftermarket ECU software is required to keep MIL (Malfunction Indicator Lamp) off and is required to maximize performance gains as advertised. Individual results will vary.

The car is so cool when its not stock that he has to wear a hoodie lol

[@lukesoderberg3920]

Yoooo I know it’s so cool

[@Mikebike68]

I’m glad to see it presented like this. I don’t want a loud 4cyl exhaust- it just doesn’t appeal to me. Nothing but sound samples of ppl with other exhaust mods before installing this. To me this would make the most difference in flow with the least amount of noise increase. Tasteful sounding and would enable a stage 2 tune from what I understand.

[@souternazguy1988]

Sweet! I literally just putting this in my wishlist the other day.

[@DarNico]

Sounds good for just the free flow cat and down pipe. Not bad. The Valved muffler system is where it's at tho. :)

[@colethorin]

can you get just the valved muffler system or do you have to buy the whole exhaust?

[@dogchainsaw3923]

Yo this is what I was searching for! Ty

[@6402457]

I got this same set up. But with a center resonator delete. The exhaust note and sound is perfect not to loud and barely any drone. And the DSG farts it makes hella loud & aggressive that it breaks necks hahaha

Nice! but when is the ECS Mk7 exhaust coming out....?

[@josecoreas554]

How much of a difference in sound vs a catless downpipe?

[@lenwoodcruze3594]

I'm looking forward to something just like this but featuring a MK7 Golf,preferably a Sportwagen.....I have a 2016 GSW.

[@patrickpoelmans9923]

Still too quiet

[@MrGhoulie]

Loud 4 cylinders sound horrible. I like my 4 banger to be a LITTLE deeper and louder than stock. Let’s not forget the A4 is a luxury sedan and not meant to be loud. The S4 is where it’s at

[@thenotoriousjoey9956]

Mr. Ghoulie I agree I want to upgrade my exhaust on my a4 but I ain’t cheaping out on it for it to sound like a fart can I want to get a awe touring exhaust or one of those ecs ones it’s pricy but then I also need a tune for the down pipe shit😔

[@mattcrompton5174]

This is with the stock exhaust system, the only change is the high flow cat, they sound 10x better with a good catback on them

[@V.marroquinn]

WHERE IS THE ONE FOR THE AUDI A6 2008 3.2 MAKE ONE AND I WILL BUY ASAP

[@blizteredthumbs7911]

I got the IE catted downpipe.. I'm pretty miffed. Does ECS send on shades in their pack? I didn't find a pair in my package from IE. 😎

[@braxtonhamby9658]

Nice but everyone’s already done it should’ve done a valved catback

@@hexsdouble6seven911 stage 1 is only for intakes but might help the light itself. You need a stage 2 tune to fully take advantage of the catless/highflow cats. A heat exchanger is recommended at this tune level.
