X-pipe а bad idea for this engine. The sound will get much worse. Instead of a brutal v8 sound, you get a buzzing of v6.
The best sound from this engine is the standard exhaust and downpipe without a catalyst. And open the flaps on the exhaust to permanently (I kept the axis welded).

Also for this engine must have cool running oil and water thermostat.
