I just bought a Flowmaster 40-series "Delta-Flow" muffler for my Festiva. It has a 2.5" inlet and outlet. It isn't a glasspack or anything, just baffled.

Does anyone have any experiences with this muffler? What are some characteristics of the sound? Like is it raspy, low, etc?

It will be connected to a Mazda 1.6liter, 16-valve, DOHC, turbocharged engine, through the factory catalytic converter and 2.5" piping. No resonators.

I'm guessing its going to be fairly quiet, seeing as I can idle the engine in my garage at 1am with an open exhaust (straight out of the turbo).

Any help is appreciated.

 

I have a 30 series on my CRX. Let me tell you... with the header, cat, no resonator and all the tubing, it was so freaking loud and tinny at specific RPMs... added a resonator and it's deep pitched and sweet now.
