exhaust

[devildriver422]

hey what is a good exhaust for 400ex with good power but about sound:my friend has the yoshi sli-on in the nacs volume 8 catalog idk the model it doesnt say i need something about that loud or it can be a little louder...i want curtis sparks but ive heard its really loud, is there any way to quiet it and still have good power?

[JRDrider22]

curtis sparks is the greatest for power

[devildriver422]

yea thats what ive heard but how loud are they

[Hillshooter]

As far as I'm concerned Sparks is the best pipe out there but they are extremely loud. I was told their right around 102db

Sparks is the strongest but for sound I would check HMF with thier quiet core.I currently run one on my YFZ and it is quieter.

102 db isnt really that loud... im pretty sure theyres much louder out there

[devildriver422]

how loud is a dmc alien...and again the yoshi idk wut model tho its in the nacs vol 8 catalog just the sli-on
