Exhaust system OR Tune?
I have about $1000 to spend on the MH for this years camping season. It has come down to installing a complete Thorley exhaust (headers and muffler) OR a Thorley muffler and a Brazel's or 5star tune. I have several questions. 1) Would getting a tune and muffler cause higher heat at the manifolds, which would cause problems with the dreaded V10 manifold bolts? 2) Is it worthwhile to just replace the muffler, or does the whole exhaust system need to be replaced (adding headers) to help the engine breathe. 3) Is the tune customized to your existing setup? If so, would it be in my best interests to replace the exhaust system this year and then do the tune next year?
