It seems everyone is calling the 17749’s a very quiet option. Is it like factory quiet, or does it have a little rumble? I’m wanting someone that is slightly above factory noise to at least let you know you have some motor.

If that’s what you’re looking for in a muffler they’re the right ones for you.

Just replaced my Flowmasters with a pair of Borlas . The sound is just right...inside and out

No, they are not factory quiet. Louder, but not obnoxious

Pipe size makes a big difference - 17749's and their 2-1/4" equivalent are different in their noise level. 2-1/4" are almost factory quiet - the 2-1/2"s quite a bit louder but not obnoxious or ticket worthy.

Were I to redo mine Lemans, I would have 2-1/2" head pipes with 2-1/4" tail pipes. My T/A has the Thrush setup; quiet but not OEM quiet.

I've had the same 17749's (with an H-pipe) on my GTO now for about 20 years. Able to hold a conversation quiet inside the car and a nice rumble outside. With no other changes but the mufflers, I went from Flowmaster 50 series and an incredible drone inside the car to Dynomax 17749's and no drone or resonance.

Spintech for the win. Can get them made as long, thin case, and/or wide as you can fit, "stuffed" inside if you want as well to knock down sound. Great muffler.

I have Flowmaster 40s that aren't for everyone. They're loud...but I'm loving the exhaust note/tone. Very aggressive, but at 55 mph (3.23) with windows down we were able to easily talk. Might get a little old over time... we'll see. It's always been part of the musclecar experience for me.

I need to record it.

I’m considering the Venom 250 in 3”. My current engine makes around 660hp. Next year when it’s turbo’d it will be in the neighborhood of 1200hp-1300hp

I ended up going with a set of 3” Hooker aero chambers and 3” Pypes exhaust. Everything fit great. No complaints. We are finishing up the efi conversion but it should be running in the next couple weeks so I can see how it sounds.

Pypes full 3” exhaust with X and Hooker Aerochamber mufflers

Sounds amazing!!

Which Thrust do you have? I was thinking of using the Hush Thrust, but wondering if it might be too quiet on my Esprit.
