too much resonance
I've finally had it. My winter upgrade will be getting rid of the B&B Muffler. It always had too much resonance but, the past 2 years and especially this year the rattling is too much. Especially, below 2800 rpm.
The car is a 1985 w/ a 1995 3.6 with B&B headers and 2 in 2 out muffler. Done some looking around and would like to find a muffler that bolts on to the headers. Fabspeed Maxflows look like a good choice but, I don't need to by the whole package, just the muffler. Does anyone have any suggestions/ |

Seems to me that B&B headers have non-standard spacing, and no other off the shelf will bolt up.

Cut one outlet off and weld it up. Test it first by just capping it.

I switched it out for a Dynomax 17725 dual-in dual-out. This is a 2-1/4" pipe size muffler. It is real cheap and sounds a lot better. I commonly get people asking what it is because the sound is nice. (It is still louder then I would like but I like a lot less noise then most people. I want to be ignored when I hit the gas!) I keep one of the outlets blocked for normal driving and I uncork it for events because people like to hear noise when you compete! Magnaflow makes a similar sized muffler (#11385) in all stainless and a number of people like it but it is too loud for me. (Remember I like quiet and I would never go for a dual out street system because of the increased noise.) Here are a couple threads on the subject. I know the first one discusses the 11385. B&B Exhaust - Need to lower noise levels in cabin B&B Heat Exchangers with other than B&B muffler?
