I have the Flowmaster 4" turboback exhaust system on my 6.0. I like it a lot. The exhaust is not too loud but noticeable when idle until I step on it. Plus I paid less than $350 for the whole exhaust system.

The main problem with FlowMaster is that their systems do not allow you to keep the catalytic converter. This is a big warranty concern with a lot of people. I went with MBRP's 4" turbo-back system because MBRP's system allows you to keep the CAT, thus avoiding any warranty voiding issues

I’ve been researching flowmaster and it looks like their kit (#17377) for my03-05 (auto only?) reuses the factory cat<O

Chiahunw can you hear the exhaust while idling, cursing around town 30 to 40 mph and on the highway 60 to 80 mph empty and loaded?

Anybody have any sound clips?
thanks

The kit does include adapter to re-use the cat, but my cat ran away during the installation.
Anyway, I couldn't really hear the exhaust sound when the windows are all up at any speed. Flowmaster 50 Series will not make loud muffler sound until you gun it or put some load on the engine.
However, I switched the original Flowmaster 50 Series muffler to the Flowmaster 40 Series Delta Force Race Muffler not too long ago. With the new 40 Series muffler, the muffler sound did increase from idle to full load inside the cab with windows all rollup.
