Need quick exhaust help
I am installing my mbrs6200p 4" exhaust. I do not see anything in the instructions or on the muffler that says what direction it should flow.
On the inside of the muffler, do the louvers go in the direction of the motor to catch the sound ? or out to the back..

Open side of louvers pointing to the rear. I have heard you can mount it the other way and it is supposed to be quieter, but I don't know that for sure. It seems like it would also create too much drag that way.

Yes, That is what i found, or should i say my girlfriend found for me on the web. She searched the web for an answer as i cut the 34" pipe to the length i needed being a short bed. it says, if it is the other way it will work but it will cause more noise in the cab. All is good and done. Took me about 3 hr by myself. The hard part was trying to keep the pipe up to the turbo and in place with not much room. I finally used a bunge cord to strap the bottom up and was able to hook everything up..

I just noticed my 4" is hitting somewhere. I have to get one more band clamp. One stripped out on my magnaflow exhaust. The nut they put on must of been striped or croked, I can't get the T-bolt out and new nut didn't help. I wanted 4" mega clamps but couldn't find them anywhere.

Chances are it'll push against the bell housing, mine does and it wanted to rub on something else but I don't recall what it is at the moment. I had to adjust the pipe as best I could to keep it from rubbing on things and had to adjust the spare tire so that it didn't rest on the exhaust pipe.
