1970 Z28Transverse muffler sugestions

[GrumpyJeff]

'So i finally got my complete Waldrons exaust system installed on my Z28. out of the box everything looked great. But during installation i had a few minor issues with fit. With the most signifigant being the right side head pipe coming out of the manifold was a inch or two longer compared to the original oem pipe that we removed, which in turn thru everything off the rest of the way back including the muffler being way out of wack as far as fitting in the limited space behind the rear axle. No biggie , just had to go back and trim a good inch at he front of the head pipe to get every thing to fit as it should. Since all my original hangers were fine i decided to reuse all of them. Everything lined up pretty good , but the entire system felt a little snug to the bottom of the car,And the aluminized finish looked great . but Once the car was started I was immediately disappointed with the Tone of the optional "Imposter" muffler which was supposed to have a more aggressive sound than a stock style replacement . New car quite is all i got ! It dosent sound bad at the rear of the car , but at idle and going thru the gears even at full throttle it just dosent have the sound i hoped for. not sure how a Solid lifter,11.1 motor can sound so tame ? HaHa , the car does have all its born with California smog in place for what its worth

Thanks for the report. Makes me not want to try an Imposter muffler. If still unhappy and not too worried about originality (can't really see much of the muffler anyway) a popular option would be to swap out the transverse for one of these cross flow mufflers from Dynomax and it's relatively inexpensive. They are a great sounding muffler.

Not sure what pipe diameter you ended up with but they make these in 2 1/4" and 2 1/2" I linked the 2 1/4"
