Exhaust feedback needed...
I'm new to the thread, and I'm thinking about changing out my exhaust (cat back) system and I need some feed back to quiet it down some. I current run an American Thunder (2.5 in.) Flowmaster system. It sounds mean at idle, and WOT, but it has the dreaded 2,000 RPM drone that they are infamous for! It has gotten worst since I upgraded my engine and rear end gear. I'm thinking about going with Borla Pro XS or Corsa DB ( drone buster red series) mufflers. Does anyone run either? If so, how do they sound vs Flowmasters? Do they still have drone?
My current set up is a DSS 347 stroker motor 10.1:1 comp. with TFS stage 2 H.C.I top end kit,Mac equal headers, UPR off road x pipe, and 373:1 gears!
Any help will be greatly appreciated!!
