I'm on Flowmaster's site right now looking at their Super 44 Mufflers but I have no idea what IN/OUT means, and I'm confused about the C/C, O/C, C/O, O/O, O/O SAME SIDE. I'm planning on purchasing the 2.25". Any help would be greatly appreciated.
I should elaborate. I have used flowmasters in the past for many applications and my number one complaint with them has been excessive interior droning in most cases. The Sami is a short vehicle but poorly insulated. Mine drones and it's fully rattle trapped and carpeted
Your performance gains with a flowmaster over a decent universal quiet muffler will be negligible at best.
I bought my Samurai with 2.5" and Flowmaster and it was unreasonably loud and raspy so I removed it and went to a 2.25 using new universal Magnaflow cat and muffler. It's a big improvement but I'm still going to fashion some sort of silencer at the end for street use. That constant monotonous howl does get old after a while, especially with the ragtop.
Expect a Flowmaster alone to be loud with high levels of interior drone, especially at highway speeds. If I could go back and do mine again (ie. I didnt weld the whole thing up) I would keep the universal cat and use a decent quiet muffler.
If you dont hit the highway often it might not be so bad.

I'm quite fine with a loud noise. My father has two older model pick ups (67 & 65) both with Cherry Bomb mufflers thrown underneath'em and I never get tired of waking up to it. Oh, and about that drone on the interior. Is there anything I can install that will make less rattle or none at all? Thanks for all help and info guys!
This will have a high rice factor over an old school high compression V8.
To minimize interior drone you might see if you can position the muffler further back and have a look at other mufflers posted by Max. With a 2.25" and no cat even a quieter muffler will deliver ample exhaust note. A couple things that make this a bit louder is the fact that its a very short exhaust system (makes quite a difference) and probably has no cat.
Mine sounds pretty good and not to ricey configured as it is and I can listen to Tom Leykis at 70mph without going deaf (if no hills or headwind) but I would actually like quieter.
Keep us posted on what you choose and the results.
Oh yea, I have dynamat like stuff (rattle trap) on floor and sides with full carpet, it did help but I did it for temperature insulation as well as sound (AC equipped)

Alright, well I will be purchasing me some Dynamat then! I'm going to stick with the 44's but I'll be careful about the drone. I'll keep you posted on the results and record a video for further review. Thanks for all the help!
