Exhaust Install

Here's some pics of our install of a Bosal Brospeed cat-back exhaust system on my Dad's 1994 325is. It sounds great; it gave the car a nice deep growling tone. The install was very simple, Here's how to do it:
-Undo the 4 bolts connecting the 2 pipes to the catalytic converters (these may be quite tight so try using some liquid wrench or WD40)
-Undo the 2 mounting clamp bolts on either side of the muffler (make sure someone is supporting the muffler so it will not drop)
-The clamps may be slightly rusted to your muffler so you can use a flat head screwdriver to pry it loose
-Slowly remove muffler being careful not to bend the 2 metal sleeves inside the pipes that connect the exhaust to the cats (one of which was welded into the cat pipe)
-Now that your old exhaust is off it's time to put the new one on
-Insert the non-welded sleeve into the exhaust pipe
-Move your new exhaust into place making sure to line up the pipes
-Attach and tighten the mounting clamps to the tabs on either side of your muffler
-Now tighten the bolts connecting the exhaust to the cat pipes
-You're done! Go test that sucker out!
