So the turbo I'm about to pick up has a Manzo exhaust and it sounds great, but just a bit loud when driving. I don't want to choke it down too much, but I want to quiet it up. Any suggestions on mufflers that are not too restrictive?

 

The big Magnaflow that's been the recommendation in every one of these threads created since about 2008.

 

A quick search will show that the MagnaFlow muffler is MT.net approved.

 

Thanks guys!

 

Magnaflow 12589 is the muffler you want.
