Would there be any benefits to swapping out the stock muffler from the chain and replacing it with a magnaflow or a flowmaster delta 40 universal? Or should I just save my money and get someting like the Megan OEM style? I'm just curious because it seems like the OEM piping is good it just seems the muffler is extremely restricting. Any comments would be greatly appreciated

 

There is some improvement but its nothing earth-shattering. Theres been some dyno testing done with the axleback removed which gave about a 5 HP improvement so any muffler will offer less than a 5 HP gain. Its mostly an appearance and sound upgrade with a few HP to boot.

 

so it sounds better than stock? is there a pretty good improvement on sound? not overly done, but better than stock? How much does it run for the install and the muffler?
