i was wondering how it would sound if i put the comptech axlebacks on my 01 cls with the stock b pipe and headers. how does it sound inside the car when your driving on a highway..is the interior resonance loud?...also does anyone one know if they are chambered or straight through mufflers?

 

I have the Comptech headers and axle backs with the OEM B pipe on my 6MT CL. They are only noticible when you step on the right pedal and open up the throttle. At cruising with the foot barely on the pedal or with cruise control on, you don't hear them. I like them. They give a bit of low end grunt to the CL without any ricer buzz.

I believe they are chambered.

 

they are straight through
