Anyone know how to replicate this sort of sound?

melvinmelvin, do you mean you have no mufflers at all? Why do you step through pipe diameters? Is that a way to create/eliminate some resonances?

right, have no mufflers

the different pipe sizes have to do with space constraints
cannot do 4 * 3 inch all the way

Thanks! I tried no mufflers and it sounded so damn loud I even stopped thinking about cut-outs

I have the engine behind me when driving,
so the sound isn't too bad (for me that is).

upd
I think I have just found a much better approach to the sound I was looking for

It's chambered muffler without any packing. Having played with Glasspacks much enough, I decided that classicchambered.com ' s "mufflers" would be way too loud for me due to their size (not enough width), so I just obtained the part of maximal dimensions I could fit...from some trusted vendor
