Custom 2.5 inch minimized bent exhaust pipe (no resonator)coupled with a Thermal R&D exhaust.
-custom 2.5 exhaust pipe= $110 (including welding and instalation
)
-Thermal R&D exhaust muffler= $350
Installation on the muffler is easier than removing the stock one. Thermal R&D exhaust systems are supposed to be dyno "researched and developed". I have no clue what the output HP was supposed to be, however, I really didnt feel a daym thing
. Similar to the thermal stealth, it has a very deep tone and mellow (not screaming) sound. The exhaust tip is not very big neither.
