Best Exhaust for 1970 Challenger 340

[70silver]

Hey, are there any recommendations for exhaust on a 340 Challenger? Right now, I've got stock exhaust manifolds that go to cherry bombs. I've looked into TTI since a lot of people recommend those, but I was wondering if there were any better alternatives. I'm looking for something that will give it a good sound (Loud, choppy, maybe higher pitched than an H pipe) and could also improve the power a little.

No such thing as 'stock' headers, there are stock exhaust manifolds or aftermarket headers.

Probably the best header for a 340 are the stepped 1 5/8" to 1 3/4" TTI headers. You pays your money and get no nonsense. Thought I saw someone on here selling a used ceramic coated set for $675 plus shipping. That's a bargain!

the lopey sounds comes from the cam though right? I got that sound using Voodoo on my 71 340. I just paid for my TTI long headers and h pipe full exhaust today. 3" will give you a deeper sound but i just went w 2.5" as recommended for my 400hp output.

Although LEOs don't like the loudness (people complain to them, so they have to pull you over), open headers is the best sound on a Mopar! Those electric exhaust cutouts are a great invention! I've got Flowmasters on my 70 Challenger and love them. I bought them from Flowmasters when they were a little shop in Santa Rosa! I recently purchased a set for my 71 Barracuda and much to my dismay discovered they were made in China! Ugh!

Flowmaster does have a range of options that gives you different sounds as well... i have 40s on my challenger and 10s on my cuda.. 10s are as close to open headers as flowmaster makes (at least was when i bought them some years back)

I bought a full exhaust for my stock manifold 70 challenger 340 from Tti. It is 2 1/2” all the way back and came with dynomax mufflers. Not as loud as flowmasters but I like it that way. Has a slightly bigger cam with a little lope and the bigger than factory 2 1/2” should help it breathe a little better. I would recommend this system
