....is there such a thing on the market? I wanna pull the plastic baffle from on top the engine that has 6.6L molded in it and plug that hole. Any suggestions?

I believe I answered this for you in another thread of yours. Go to Home Depot/Lowes and buy a 2" rubber cap. Done.

I plugged it on my 03 and didnt notice a difference in anything so I put it backto stock.

Oh really, no noise difference?

Yeah, I remember now 06D, thanks for the info...

There could possibly be a noise difference, but not enough for you to hear. Get a 4" or 5" exhaust, delete the cat, delete the muffler, do the mod I told you about to the air intake, plug off the baffle, and you will notice a nice increase in whistle. Its addicting. I will turn down the music to listen to the whistle.

Yeah, no crap....I did the intake mod today....it was very easy and felt alot better than spending $400 bucks on an aftermarket. The whistle is noticeably louder. I put my MPRB 5" cat-back on tomorrow. I'll let you know how it goes.

PS....I cant tell a difference on the Predator between the 85 and 120 tunes. Am I missing something here?

My 04's was plugged and my 07's is plugged. The throttle noise is throatier.
