I want to throw a test pipe or the UR mini-muffler on my stock downpipe/catback. I don't want to put any other exhaust on for now. Does anyone have any feedback on doing this? Possibly a video? I've searched on youtube and couldn't find anything. Thanks.

I want to know too.

Im running just a NRG Tech test pipe and nothing else on the exhaust and its awesome. Sound is still stock, maybe a little more basey, but thats about it.

i have the u/r test pipe and d/p.car sounds likes stock like,kust a little more bass like GrkBallaG said.

I have MXP downpipe and Test pipe with stock catback. sounds just like stock just a lil more smelly but not to bad
