muffler suggestion
 

So my 2000 blazer needs to be able to exhale a little better. I want a new muffler, something thats throaty outside the vehicle but isnt too loud or that drones inside the vehicle. I have tried a flowmaster 40 on a jeep cherokee and it was still pretty noisy inside. Any other suggestions?

I was happy with the Flowmaster 50 series Delta Flows on my '02.

delta flow flowmasters are nice. but magnaflow mufflers are exactly what you are looking for. loud outside but quiet inside, also expensive.
