Exhaust Muffler

[crimson11]

Wanna Know what would be the best muffler for my 1.6L ST 3.5" 4"?? outlet or other suggestion ?? I like the deep tone sound but also like the heavy deep tone like the one's you would fine on some Muscle car. Youtube doesn't really help its not specific on what muffler is being used. So what do you use? But i do want the most Horse power out of it, that it can help me.

I would say avoid using anything too loud.... meaning a glasspack.

I would suggest something along the lines of a turbo style muffler. It'll open it up a bit without sounding obnoxious.

edit: I've only heard one 4AF with a straight through muffler sound good, and it was a whole HKS sport catback

A 3.5 of 4 in exhaust would kill your back pressure thats what they use on large turbo exhaust. you would want a 1 7/8 - 2in cat back with a res. and a packed muffler.(ie what Rob said the HKS)
