Checking to see if anyone has input for a replacement exhaust for a 4.0? I have been directed to a Heart Throb with the standard standard turbo muffler. I am more interested in horse power gain than noise.

thx

I put in flowmaster pipes; all new from the manifold back to the chrome exhaust tip. As for as power gain goes, it has definitely improved.
