I was told by my friend that it is bad for your valves in the long run. however i was unable to confirm that with any other sources.

From what i have read about it(very hard to find anything on it) it seems you only have valve problems if you dont have atleast some back pressure. All the info i found was kinda hard interpret. nothing specificly about removing the mufler. so i may be completely wrong.

If that is true, i would assume scince the cat and resonater are there, they would provide enough backpressure to keep that from happening. However im not about to risk messin up my motor just to find out. Try callin a muffler shop and see what they can tell you, Then again they might just tell you its completly necessary so you will buy something form them.
