Right now I have 40 series SIDO, but I have a 10 series muffler sitting in my room and I'm afraid of the low end loss it might cause. Will I lose any more power on the low end than I did with the 40's? I still have my two cats on also. Thanks for the help guys.

 

you might gain some switching from a single in dual out to a single in single out

 

well I would have it split after the single out for duals...would that make any difference?

 

Other than a noticeable difference in sound output, you won't notice any kind of performance difference.

 

agreed not much of a difference

 

Naw the difference from 40 to 10 series wont be anywhere but noise.

 

Alright guys thanks for the help...I'll prob have it put on tomorrow afternoon if they can get to it.

 

There will be a very very moderate loss due to tail pipes mounted to a Y pipe, but nothing noticeable unless you towing 5,000lbs+.

 

Dumb question here. Which is louder? the 40 or 10? or if not louder what's the sound difference?

 

The 10 is noticably louder.

 

10 series is louder due to its single chamber design in a 6.75" case. 40 has a 5x8x13 case in a 2 chamber format, original 40s are 4x9.75x13.

 

Not a dumb question. 10 series is 1 chamber instead of 2 or 3. It's virtually the same sound but a tad quieter than no muffler.

 

Actually when the 10 series was on it was louder than when i had no muffler.

 

Ah that's interesting, guess it's the way it's designed and echoes off and what not

 

Yeah single chamber mufflers are louder than most straights. Straights rasp much more though, but the idle of a single chamber is much better than a straight systems is.
