I've been thinking about getting a 2.5" center in/ 2.5" offset out Flowmaster 70 series muffler for my Cherokee to replace the factory 126k muffler and tail pipe, but have seen that Flowmasters don't "flow". Is that true or should going with one that large behind my otherwise stock 4.0l I-6 negate the accused "restriction"? Reason I'm thinking it shouldn't matter much in my case is that the 4.0l is 242ci while the muffler is intended to go under full size trucks, vans, motor homes, ect that use large displacement V-8's and diesels.
