derffred Posted July 25, 2012 Share Posted July 25, 2012 Hey all - I've had my Exhaust Setup for quite a while now (Crucial Racing UP, Invidia 3" catless DP, & Magnaflow 3" CBE) and the noise was finally getting to me I did a quick search on here and read about adding a Magnaflow Universal Muffler (Part #11219). During the install, I decided to take some pics and share my experience, unfortunately, I thought the diameter of the Midpipe was the same diameter as the Muffler, so I cut the Midpipe exactly 20" in length, not knowing the muffler's diameter is actually bigger than the midpipe, which would allow it to slide inside for a leak-free setup. Long story short, with the clamps I'm using.. it's leaking very slightly, enough to feel it with your hand, or hear it at idle (from outside the vehicle) if you listen very carefully. I had clearance issues with the muffler contacting the driveshaft tunnel, so I made a small bracket to pull the exhaust more towards the passenger side, using the holes from the driveshaft heatshield. Thoughts on the added muffler? It's perfect.. idle hasn't changed much but driving part throttle is awesome, windows up, down, it's great. Not too loud, I can have a normal conversation inside while driving, not worrying if he/she can hear me; and you can still hear the Boxer sound, IMO the muffler contributed with a deeper sound than without the added muffler. I'm very impressed. I haven't driven full throttle yet, as I'm breaking in my new clutch setup.. but I'm sure I'll add further thoughts in a few weeks. Anyway, on to the pics.. if you have any questions or comments, feel free to post up.

vkchu Posted July 25, 2012 Share Posted July 25, 2012 your plates look familiar... haha the exhaust clip of you revving the piss out of it w/ the magnaflows is what prompted me to get em. however, i did the 3rd muffler install the same day, and it is somewhat tolerable now.

aerophool Posted July 25, 2012 Share Posted July 25, 2012 Is that better (wrt to sound & performance) than adding a resonator: http://www.summitracing.com/parts/WLK-22538/ ??

derffred Posted July 25, 2012 Author Share Posted July 25, 2012 Haha when I made those videos, I had the Crucial Racing Downpipe, not the Invidia. Maybe I should make some more videos Link to comment Share on other sites More sharing options...

Unless I'm very mistaken, that Magnaflow is a straight-through absorption type muffler, often referred to as a resonator.

derffred Posted August 21, 2012 Author Share Posted August 21, 2012 It's a little louder than when I first installed it, but still a huge difference compared to not modified. Link to comment Share on other sites More sharing options...
