I appreciate all the hate posts about the Flowmasters but I'd say that applies to the 2 and 3 chamber designs. The single chamber 10 series flow really well. I can notice a night and day difference in how the 10s flow compared to my 40s.

Can you please share the data? I haven't been able to find anything for flow numbers, or back-to-back dyno or dragstrip testing.

I am of the opinion that between all the different exhaust parameters and the subjective nature of sound, that making any comparisons between mufflers is a futile exercise.


I researched mufflers to death and found many cases where ones that worked great for some were terrible for others. I think you just have to keep swapping them out until find that right one that works for ya.

I've been down that road before using the dragstrip. Spent thousands of dollars over several years and couldn't find anything significant with muffler changes, but found quite a bit with pipe changes.

So these days I tend to pick a muffler on sound quality and then just make sure the pipes are the proper size with mandrel bends with a good X-over.

The best sounding car I ever had was my old SD clone trans am with an "H" crossover, 2.5 full exhaust and 2-chamber 40 FM's. Over the years I have had an "X" crossover with FM's,(40 & super 44) Goerlich's and Jones Full Boar "V" tube muffs. These were used in 3 different engine combinations in my '79 and none of these ever sounded as good as the SD clone.
I am convinced that the "H" and "X" type crossovers plays a significant part in the overall tone of an exhaust system, regardless of muffler used. I plan to swap out the current "X" and return to the "H" configuration for the '79.

Absolutely! X is for performance, H for sound. I've always been able to hear a very distinct difference. I have an H in my car.

I don't go to the track anymore so a few horsepower lost isn't a big deal for me. I spend more time driving the streets so sound is my preference.

H pipes definitely sound better than an X.

I'm bouncing back and fourth between how I want to redo my exhaust. It's easier for me to buy a universal X-pipe setup, buy I really like the sound of an H better.

Here is a video I just uploaded of the 10s on my car to compare to my other video of the 40s:
