I considered Super Trapps - that is until I heard a few cars with them. Most, to me, anyhow, don't sound nice and burbbly (new word) just a somewhat muted blatt. Not even sure about my 3 chamber Flowmasters yet until I get a few miles on them. They seem to drone even driving up and down the driveway and around the block. I do like Smithy's but hung outside like a 'bucket.........

I put a set of lakester headers on it http://www.lakeheaders.com/Home.html with Car Chemistry baffles.. I also installed a set of Dyno Max super turbos on my buddies 54 chevy that had flowmasters on it. They sound sooo much better

Mufflers???

traditional glasspacks on the monte. flowmasters on the z28. each car should have its own depending on its personality.

I'm running Flowmasters, but am changing to Magnaflows soon.

It’s funny that this topic should come up again now, I’ve been kicking around changing the mufflers on my 57 Plymouth. I really fell Dons comment form a couple of years ago really rings true.


“…..The exhaust note has to match the era we are shooting for…..”

When I first put the car together I put on a set of Dynomax mufflers and absolutely did not like the sound. I pulled them off (they eventually ended up on the Transam which they sound great on) and went with a set of reproduction 60s Hemi mufflers.

The Hemi mufflers sound exactly like I remember the stock GTXs, Road Runners and Cop cars sounding like….reasonably quiet but a nice rumble when you nail it. It also has a good sound level inside the car.

The problem is I don’t think it fits the car, I’ve been kicking around a good old pair of glasspacks.

In Il. you have to have your pick-up truck safety inspected. I think it was once a year don't remember now. I always went to the same place and never had any problems. The last time I went there they had a new inspector. He started my truck with the shop doors closed . He asked what kind of mufflers you got on there? NONE just pipes out the back been that way for years. He scraped off my inspection sticker and told me to get some on there or park the truck. Glad I moved to MI no inspections here. I hate mufflers

Inspections in IL are just for the more populated areas. I've lived in IL for about 25 years now and have never been through an inspection lane. If I lived 25 miles north it would be a different story, go figure.

Emission inspections are just in the Chi area and downstate near St Louis area for cars and B plate pickups are exempt but D and heavier are inspected all over

We have super traps dumping out right behind the door on a 32. I like them because they can be completely open or you can mute them down. We have been totally happy except for breaking a couple of screws off changing discs.

Heres what I went with

Flowmaster 2 chamber on the AMX, Flowmaster American Thunder exhaust system with 3 chamber mufflers on the 454 Chevelle, 26" Smithy's on the 34 Coupe, the Mustang has an unknown make glasspacks, some unknown make turbo style on the Challenger, and 6 VW exhaust tips on the 250 L6 on the Rat Rod.

Nice looking Moter

Lately, I've been using Velocity series mufflers from Heartthrob. It seems like many mufflers, especially stainless ones, have what I call the 'Mer-cruiser' sound - at idle they sound like they're running underwater. I like mufflers that are nice and sharp at idle and under hard acceleration, but don't have the annoying drone on the highway. The Heartthrob Velocities fit the bill for me.

glasspacks or smitties,remember load pipes save lives.
