Advice Needed: Generic Muffler for 4-2-1 header system, Too loud.. Options

[yarin]

I need a little muffler advice for my 2.0L. The car came with some early 1st generation 4-2-1 header system with a Flowmaster 2.5" "40 Series Original" 2 chamber muffler.

The previous owner was a bit of a cheapskate and never hung it properly or installed any sort of tail pipe. This winter I want to straighten it out, replace the muffler, hang it properly and weld on a rear exit exhaust tip.

While doing so, i'd like to swap out the muffler to something a bit quieter. It's definitely too loud on the street, and I highly doubt it will pass sound at Limerock. At higher RPMs sound is also very raspy, don't like it. Even at Pocono, it's too loud to hear my instructor.

There are tons of generic 2.5" mufflers out there, but i've managed to narrow it down to a few Dynomax mufflers.

17733 14" case "sport sound" rated at 410 SCFM (plenty!)

17748 20" case "street sound" rated at 415 SCFM (plenty!)

According to the website they can support 189HP, way more than i need.

I want a muffler where i can hear myself and won't get flagged at limerock. Which would you pick? Both fit. Both are also pretty cheap ($50). Also don't want something too quiet.

Any advice would be greatly appreciated. (IMG:style_emoticons/default/cheer.gif)
