The can of the helmhotz is welded to the body of the of the high flow cat on mine so that should further reduce stress on the connection to the main pipe.

Here's a picture of mine, high quality stuff IMHO

So does the catted pipe + helmholtz work better than the stock pipe in regards to:

a. drone and
b. loudness

There is a bit of 3-4k rpm drone I want to clear up with my cat back and am thinking this resonated nameless pipe might do the trick?

The helmholtz might tone down the drone a bit, but loudness, not really if your catback is already loud. The downpipe makes it a bit louder with the cat.

Just to weigh in, I bought one of the first axelback/overpipe kits (same as Tainen, just no helmholtz or header (yet!)) last year, and mine barely drones at all at cruise. That's the original design, high flow cat in the overpipe, and no helmholtz.

Then again, I'm used to straight-pipe peripheral port rotaries, so nothing seems loud anymore...

noob question, but does anyone know if this will fit my auto trans frs with my berk dual exit muffler delete?

I believe their latest design is auto friendly now. Call them up to be double sure.

I ran the nameless axle back for about a month while waiting on my front pipe. I got a newer offset axle back and it was supposed to be pretty quiet. I thought it was too loud. After installing the front pipe with the helmholtz chamber...I was very surprised how quiet it made the entire system. It's back to being nearly stock levels at cruise and sounds even meaner at wot. I got one of the newest revisions with the helmholtz located at the back of the pipe.

Nameless has a great rep for a reason. This front pipe is amazing. It's completely win-win. More power, high flow cat, less drone, more aggression, no rasp and impeccable craftsmanship. Now if they would only release their header.... :bonk:

Price isn't really a matter. Which of this would be the best choice of the 4?
Basically what is the Meaning of SS/TI?

Looking to pull the trigger on this overpipe/frontpipe combo with helmholtz today. I've done as much research as I could on this and so far it looks absolutely amazing, was wondering if I could get some opinions/reviews from current owners of this part just out of curiosity.

Yes it's worth it!

Saw this bumped so I thought I might chime in with some updated info. I have added a JDL UEL header and the car is crazy loud now. Strangely enough, it doesn't drone at all. Thank you Nameless.

I'm assuming this is the the helm reso? I have the JDL uel as well and I'm considering the one piece over and front pipe with HFC with a tame cat back like 2.5" resonated perrin. I guess my question is it recommended to have the helm reso with a setup like that? Currently the uel header with stock headerback is ok in terms of loudness, maybe just a hair more would be perfect without drone.

The Helmholtz resonator is designed specifically for drone not volume....

The nameless one is designed for their header but as industrial mentioned it worked for the JDL as well.
