Minihaha .. Thanks for this..
you beat me in opening the muffler first .. Nobody has done this in our local forum yet .. when I posted about exhaust rattles in my exhaust system there, somebody advised that the rattle was coming from the muffler. I was planning then to rip it in some future time when I will have a replacement muffler. Looking at the pictures, I can deduce that the rattle is coming somewhere else, i,e, from the secondary CAT. (I will have that 2nd CAT ripped to see what's inside).
I have a Headers made by STIVO (similar to Speedlab's); selective rattling is observed around 1k and 3K RPM's that developed slowly in due time. After more than 1 year & a half, it developed into an irritating one.
This is my planned mod for 2Q/2016.
1. Headers already in place as replacement of the exhaust manifold/primary CAT
2. Secondary CAT to be replaced w/ High-Flow Type (ECO III Universal)
3. Stock Muffler for replacement with the ff. choices:
- Flowmaster Super HP-2 Series muffler
- Walker Pro Fit muffler
- Flo~Pro Heavy Duty muffler
4. Resonator may or may not delete
