Default 1969 Camaro Exhaust

Hey guys, I am changing my exhaust setup on my 1969 camaro. The car has a 04 LS1 engine, bolt-ons only.

I originally had 2.5 true dual with x-pipe and knockoff 3 chamber flowmaster mufflers that had turndowns at the axle. I thought the overall tone was great but it just simply was not loud enough.

Today, knowing this was a bad idea, I decided to get the muffler shop to cut the mufflers off and weld in two straight pipes. I just had to see how loud and obnoxious it was. Obviously, it is loud and sounds like pure ***. The overall loudness is about right, perhaps it should be a little less loud, but I have to change the overall note of the exhaust.

Youtube link of straight pipes:

I was thinking about going with a flowmaster super 10. I am cautious about the rasp that may still exist? What are yall's thoughts about adding a dynomax bullet after the X pipe before the super 10? Or, am I totally in the wrong place and should try something more along the lines of flowtech terminator?

Since the car is more old school, I want to try and get as deep, classic of a sound as I can get.

Jason

Thanks for the reply. The 40's do sound nice. I am also debating on those as well. That idle vid is wicked!

I dont know why, but I keep leaning towards a bullet as a resonator along with the super 10.

Decided on the Super 10's with a J-Pipe resonator effect welded before the muffler. Hopefully this will tone things down some and add more refinement to the exhaust note.

the Flowmaster 10s are the best sounding mufflers on an LS1 I've ever heard

do those without worrying about any resonator or bullet crap, they sound amazing but they are definitely loud (the duals I heard were 3" not 2.5" so yours won't be quite as loud)

New exhaust installed. As stated before, 28in resonator pipes, 2.5 in dual, xpipe, and flowmaster super 10.

car has ZERO drone or rasp in the 1700 range. Some minor pop shows up at 3k, but it just sounds great. Car is not as loud as I thought it would be. It has a different type of tone to it that I have not heard on hardly any other LS engines yet. Kinda of a hybrid between old school muscle sound mixed with some modern notes at the upper RPM. Overall I am happy with the results.

Also, Thunder, I used your videos to determine the Super 10 feasibility for my ride. Many thanks for posting those!
