I have the Nameless 3 inch OP/DP combo with straight through resonator and helmholtz resonator and Perrin resonated 3 inch cat back. I ran it with a Borla UEL header for a while. It was great. Loud and rumbly past about 3k rpms.

OP if you want to make it quieter, go with the Perrin 2.5 inch resonated cat back

how is the Nameless 3" OP/DP treat you? I heard there is clearance issue? my car has dropped about 1.25" front and rear, i want to know if the Nameless 3" OP/DP will cause problem or not.

I'm running the Nameless 3'' front/overpipe.

No issues with clearance, lowered 1.5''.

UPDATE:

I was checking under the car, I can't see any part of the exhaust touching anywhere, BUT I could see water coming out from the gasket between nameless OP/DP and PERRIN MIPIPE Resonator... does it means I have a leak?

I have OFT STG2 EL and I got a P0420 code while i was cruising on the highway.

Fuck! so many shit all together. The resonance/vibration is very audible on second/third/forth gear and almost inexistence in fifth gear and none in sixth gear.

Does it make any sense? I would say the sound it comes from the middle of the car but not that sure about it.

Could it be the vvt getting amplified?
Here no one know this car, so I need to diagnose the problem alone... Would be a shame if I have to start throwing away new pieces of exhaust due to this annoying sound

No clearance problems. I'm lowered about an inch and because of that I avoid speed bumps in my area. Those suckers are tall!

I'm freaking out now, because the mechanic that did the work is out for 2 weeks and I'm worried it could create some problem if it's hitting or rubbing somewhere, hope not.

I have catted JDL EL, catted/resonated Nameless 2.5" downpipe, and A'PEXi catback. I too have a tin like vibration when I accelerate, even worse during cold start. I'm thinking it has more to do with the EL header than the catback, but a catback known for having a deep, deep note may help quite a bit.

Looks like you have leak if you can see moisture dripping from gasket, did they use new gaskets ??

P0420 is catalytic efficiency code for primary cat, if your headers are catless you will get this code occasionally can also be caused by leak near o2 sensors, OFT tunes even stage 2 do not remove code, this can be done in romraider just find the CEL code and set it to disable.

I would fix the leaks first then reset code then see if code still returns if so disable cel code P0420 in romraider and flash update.

Code came up twice. I have a damn leak somewhere. Need to make a video to show the noise I have as well.

New gasket, grimmspeed one and graphite one for the header>dp/op.

One leak is between dp/op and Perrin catback mid pipe. I'm sure about it, seen moisture dripping down from the gasket... Maybe exhaust need to be retighten.
Maybe...

I'll probably sell my 3" Perrin soon... It's to loud even if resonated.

I think what you are experiencing is not drone, but rather rasp. Personally I'm running a buddy club catback with a catted motiv front pipe, and I get a lot of rasp after 3k.

It's a metallic sound, like a metal can shaking for vibration dunno if it's called rasp.

It's seriously annoying, it just kills the beautiful melody of my whole exhaust setup

I don't understand if it's between the nameless EL and nameless OP/DP combo or
the OP/DP and the perrin 3"

I'm thinking of buying a Perrin 2,5" I think is one of the quitest catback together with the Q300.
