I need a suggestion for exhaust system for my evo x. Currently on Greddy Sp catback exhaust. The current setup sounds ok, the problem is the echo while cruising(120kmh above). My MR evo already has a sound deadening foam inside the body, still there is uncomfortable echo in the cabin.
I am looking for exhaust that produce less echo while cruising, only loud while accelerating. (if there is this kind of setup). I am very new to evo & exhaust.
Feel free to suggest any brand or setup.
