Nameless Performance Overpipe/Downpipe Combo

[sachu]

I am debating modifying my nameless FP/OP catted combo by installing one of these resonators.

basically, cut the front pipe near the catback end and make two welds to fit this.

Would it fit ? See any issue with this route?

My problem is that I'm located on the opposite side of the globe from Nameless and "guarantee" and "return policy" are unaplicable terms due to transportation costs. I even managed to sell mine for about $100 - a bit of compensation after spending almost $700 + install/reinstall expenses

Why couldn't a good welder have modified the pipe to fit..I have seen the amazing things Russians can do with primitive tools..when I say I have seen , I mean on Youtube of course!!!!

Alternatively, nameless does make just the front pipe. That could be considered?

No I want the whole thing. They are taking care of me right now, that's good

i'm on page 67 / 204 of the Nameless header thread and intend to read every last page so i know all there is to know

My concern right now is that with my full 3" perrin CBE and 3" overpipe/downpipe + eventually headers that the car will be too loud. I'm not 17 anymore unfortunately so a sound clip would be super helpful.

I didn't see it in the thread, or maybe overlooked it. My downpipe resonator is hanging pretty low, where when I go over certain speed bumps, it scraps. Has anyone else run into this? I got it installed at a shop, so if it is error on their part, I can go back.

Damn how is it that these guys are still having fitment issues?

[weederr33]

The fitment isn't with the overpipe portion, just the resonator...

false, the overpipe rubs on the corner of the head in most cases. I have had both revisions (resonator at the front and resonator at the back) of the resonated front / over pipe combo and both have rubbed on the corner of the head and or the cross member. This is with 3 different headers (stock, fa20 long tube, and 2 nameless headers, one first batch and one cosworth style batch).

My issue isn't with the overpipe. It's with the resonator ball hanging low. Besides, I simply have the Nameless frontpipe; not the OP/FP combo.

Any word onn shipping time for an OP/FP with a cat and a resonator (2.5").

I haven't seen @Jason@Nameless in this thread in a while.

JDL makes an incredible ultra quiet front pipe and a separate overpipe piece and the fitment is perfect. The difference is that it's a regular resonator and not a helmholtz. Still a very nice piece and no rubbing issues. I was close to going Nameless on the dp/op but I held off because of fitment/rubbing issues.

i take it the helmholtz resonator is better than a regular resonator. but do u know if theres a huge difference?

There is. The Helmholtz is designed to take out certain frequencies. Blow over the top of a coke bottle for example, that's what it does. A regular resonator just reduces rasp, and some volume to the sound. Some cases adds a deeper sound as well.

Helmholtz resonators target drone. Larger resonators target rasp and sound volume.
