Exhaust options
Exhaust options So... I'm kinda old school. I really like the sound that flowmasters have on a healthy engine with headers. I'm doing a 6.0l swap into a 64 nova and would love that sound, but understand that they are detrimental to performance.
How bad are they for performance, and is there another option that gives the same or similar sound without the performance hit?

I think the whole Flowmaster choking power is a bit overstated when comparing it to other brands. Sounds like you prefer the chambered muffler sound over the straight through style. I say get it if that's the sound you like
I agree man, but something to consider is that these don't produce same sound as the old school stuff. What matters most is how the entire exhaust sounds as a unit. Something like a Flowmaster can drone and be raspy on these cars when combined with other exhaust components

Flowmaster makes a ton of different mufflers. They are not all equal. The race series arent half bad if your running duals and really want the flowmaster sound. With duals your running 1 muffler per 4 cylinders so its not as restrictive as running all 8 cylinders through one.
There are much better options but if sound is more important than all out performance go with what you like best.

I think Flowmaster's worst offender around here is the crossflow replacement for F-bodies. It's a wonder it flows at all, compared to a normal Flowmaster, most of which flow rather well, IF you get a big enough CASE SIZE. Big inlet/outlets alone won't do it. Just being a Flowmaster does not mean it will ALWAYS flow well enough for your application.

I gained 20 rwhp on the dyno with H/C/I build using a cut out to bypass my flowmaster 80 series muffler.. they definitely don't flow well.. I've heard of many others seeing the same results.. back to back dyno runs..
Sound wise and flow wise any aftermarket muffler is going to be better than stock. Here's the thing though...you are not going to see a big difference in power between most aftermarket mufflers, but there can be a big difference in sound. I'm just talking about comparing the mufflers themselves. I'm not talking different catbacks, tubing size, cutouts, etc...
