Why do 4 bangers have such a different exhaust note when running less restrictive mufflers than larger configuration engines like V8s?

I want to replace my stock R system but I'd rather have the sound stay the same than like a giant fart all the time.

umm, buy a Mugen exhaust...relitively quiet...
in all honesty...if you are running your stock cat then the 5Zigen fireball sounds real nice too...not raspy at all, but
a nice deep tone.

also might want to try the Comptech or Apexi WS series...all pretty quiet and close to stock sounding.

 

I think that the actual pitch and tone of the exhaust is related to the smaller displacement, smaller pistons. If you listen to a big displacement V-8, like a 350(5.7L) or something larger, then it is real deep sounding. On the other hand a relatively small displacement V-8(3.5L), like a Ferrari for example, it is higher pitched, much like a 4-cylinder.

It's also the timing between the impulses of the exhaust strokes...

Apexi WS all the way. Mines coming soon and can't wait.

 

FastR, makes sense! I just thought about those Harley bikes with only two relatively large cylinders. thump, thump thump. Thanks for the great info on the Mugen stuff too. RatedR
