Default Are Flowmasters restrictive?
Heard a while back that Flowmaster chamber mufflers are restrictive for a high horsepower vehicle. Is this true? Has anyone experienced a loss of power by going to Flowmasters?

Well, they are chambered so I would assume that they would be restrictive to a certain degree. Have you heard of their hushpower mufflers? They are flow through and would be a lot less restrictive than chambered exhaust.

I decided on the Roush A/B system. Found it on a vendors website for 339 bucks delivered to my door. Couldnt pass on that great price.
