911 Carrera RallyCross Project

2 minute(s) of a 245 minute read

We decided to replace the rear muffler. Just too quiet for a race car.



The fasteners fought me a little. They've been on there nearly 30 years.




Didn't take too long to wrestle it off though. 23lbs of German suasage muffler.




Found a used but good M&K locally. Only 11lbs.



Ten minutes later:



This is what the car sounded like in the shop with no muffler:




and with the M&K



A lot quieter. I didn't take a stock muffler recording. Too excited.







But wait. What's that on the parts table. Why it's a Fabspeed muffler delete pipe and it only weighs 2lbs! Let's slap that on see what it's like.




Wow, that's gotta be loud:




Yes, it is kinda loud, but souds pretty good. What about on the street?



You know, that's not too bad, even with the windows open. Not even turning heads. I think we'll leave this on for the next rallycross at least.
