I don't see why you wouldn't get the resonator. It's just a smart option if you're concerned about sound at all. High flow cats further reduce noise levels, but they aren't mufflers or resonators. Get the cat for environmental something, then replace the exhaust manifold with a catless unit.

Edit: That growing tumor/appendix is the Helmholtz.

is that the the front pipe with the overpipe delete?
Im thinking about getting this, but im waiting on Jason to ensure fitment with stock headers and nameless headers in the future

Yes, that's the piece that converts the OP/DP into one single piece. I dont' see why wouldn't it fit future Nameless headers. Nameless headers are being develop to mate to stock location just like this piece.

I talked to Jason right before I ordered mine and he said they'll fit with both. Or else I wouldn't have bought it either.

They've always espoused using the stock pickups/mating points.

Doubt that resonator would fit with an auto trans though right?

I'm pretty sure it wouldn't.


As a side note, anyone going turbo does not need the helmholtz at all, the turbo takes care of everything.

Must call Jason...

Both tones are similar, but B) commands more attention, sounds more like a race car. A) is more mellow.
agreed-
I'm running the original 2.5" axleback with 4"x6" mufflers non-offset, catted downpipe with Helmholtz, and 2nd gen nameless catless header, and it's raspy. The Helmholtz does help a lot, but the header in general adds a LOT of volume.

(note this is not the long tube header, but an equal length 4-2-1)

me likey! Thanks for your feedback!
I have 2 videos in my build thread (link in signature) if you'd like to listen/watch.

Is anyone worried that over long period of usage the Helmholtz resonator might crack at the welding/connecting points with the main pipe due to the nature of the geometry?

Not unless you hit it on something.

even then... I doubt it. The Nameless welds are very good. They have pics of an exhaust they made that was in a really bad rear end accident, and the exhaust was perfectly fine afterwards, but the frame mounts were torn off. Ask Jason to show you the pics some time... incredible showcase of how good their workmanship is.

I bet. They've got some really high quality material they build with. I still can't wait to get mine because it looks really good.
