Ok ,so I got a great price from Rosenthal Mazda so I had to buy it. Just got done installing it and going for a test drive.
First off Mazda Factory needs to turn down the Impact gun to a lower ft lb.
The u-bolt on the pipe to muffler finally broke off one of the nuts. After exstensive WD-40 applications. Then lets undo the bolts at the back of the Cat. Nice setup by Mazda. Bolts with springs on them. Only problem is ,the nuts did not come off the flanged base spring retaining bolt. After about an hour of F-ing with it,I finally got it to work. Well at least one of them. I have to go to the Mazda dealer and have them install some new bolts and springs. So far I like the sound.
Not too loud at cruising speed and not to quite cruising.
Ya know this is a great choice in mufflers in my opinion.
And why did they make the mount bracket ends on the muffler so large on the end that go'es through the rubber mount piece. I'll post some pics later on.
