Title: mufflers
Post by: babaron on August 07, 2010, 01:00:25 AM

Hello everyone. I have a '69 L78 that had no mufflers when I bought it.  Instead, I think it has what are called "firecrackers?"  A bit loud for my taste and I'd like to get regular old mufflers for it. My questions are: Is there such a thing as "date-coded or "proper mufflers for this 5E build? And, I've seen 2 different configurations in photos, one with 2 separate mufflers and another with one transversely oriented muffler in front of gasoline tank. ?crossflow?  Jerry's book shows only the single crossflow pattern.  Are all the pics of the 2 separate mufflers incorrect for this car? Thanks!

Thanks! Great reading! Ever hear of a "firecracker" in an exaust line?  Could that be a "resonator?" It has the same shape as the resonators in the diagrams.

He clarifies about the correct muffler, etc.

Yes, the term "firecracker" is used to describe that motorcyle-like exhaust popping. A resonator should actually diminish that sound.  (Technically, all mufflers resonate sound.)
And yes, some folks don't like that sound, including the police.

Post a picture....

GlassPacks were about the closest thing to open exhaust.  Is that what you are thinking of?  They are basically just a tube w/ some fiberglass packing that would eventually burn off.

I don't mean to hijack this thread but I was wondering if anyone makes a transverse muffler that has the "deep tone". I like the sound but I don't  like the looks of the 2 muffler system.

The Pypes Racepro transverse-mount muffler has a pretty nice sound!

Here's a pic of the contraption on the car now. (Hope the pic uploaded.)

Looks like a pair of glasspacks, not a transverse muffler.

I'm going to put a single crossflow muffler.  What do you think of resonators vs. no resonators?  I'm looking for a subtler growl that doesn't get dirty looks from the neighbors.
