Hello, After a lot of back and fourth on what exhaust I wanted, ordering exhaust to find out they are months delayed I decided to get the Infiniti Helmholtz AB and have the Borla Dual in and out 2.5” which will be installed soon per Speed Culteres diagram. I must say the setup currently is much...

Hello, I’m new here. Just got a 17 q50 premium. After much research on this forum, for the life of me, I can’t seem to find an answer. The only thing that comes close is a post from 3 or so years ago. Maybe something has changed since then. I love the low end torque. I am not in love with...

Hey guys, looking to buy a cat back exhaust system and down pipes. Preferably 3 inch DPs and MBRP exhaust but open to anything. Shipping to 33176

I have a '14 VQ37 currently set up with a Rev9 Axleback "muffler delete". I'd like it a bit louder, and instead of doing a full resonator delete (gross!) I was thinking of replacing the stock resonators with Flowmaster FlowFX. Was wondering if anyone has a similar setup, or can point me in a...

I love the exhaust note of my 3.7 with a muffler delete. But it's too damn loud. What can I install to make it less noisy? A resonator in each pipe? I don't want to modify anything before the axle. Don't want to spend big money (that's the whole point of the muffler delete) Thanks and I'm...

As I returned my invidia cutback last week I was thinking about spending the extra money and go with either MBRP $970 catback or the fast intentions exhaust$1300. I saw that they both don't have resonators which one comes with less rasp. I was also thinking of the MBRP and putting resonators...

What’s going on ladies and gents. Looking to pick up B0100-Q50SM or B0100-Q50S2 for 2016 Q50 3.0. I can grab it from infinity for around $500, but figured, if anyone close by wants to get rid of theirs, much rather save some money. Located in Portland, OR can come pick it up at reasonable...

So I've been wanting to get a new exhaust system for my Q50 and I don't want something as loud as a muffler delete. I took it to a muffler shop and one of the mechanics recommended that I take out the stock muffler and resonators and replace with a Magnaflow dual in dual out muffler. He said he...

I finally bought my 2020 Q50 3.0t luxe 16k miles for $28k which i think was a steal and i was thinking for my first mod to be tints and then an exhaust. I know that I have other discussions with the invidia catback but i was thinking that i don’t want my car to be that loud either so i was...

What exhaust would be louder the Helmholtz axle back or Invidia Gemini catback?

Hey I have a 2016 q50 3.0 and I currently have the ark grip catback and the z1 fulll race pipes. I was curious if there is any thing else I could add to make it sound more aggressive and loud or if there’s another brand that could achieve that. Any help would be much appreciated

I’m looking into buying a 2017 3.0t soon and i was wondering which exhaust would you guys choose the helmholtz axle back or the invidia gemini which i could get used for around $600-650. But also i want something not too loud but not too quiet so if you guys know any exhausts under 1k please let...

So I finally got my LDPs installed and now around 2.5k rpm I get a loud rasp noise, I'm running a custom 2.5 exhaust from the LDPs back with x pipe and aftermarket "no big name" exhaust, do i need tune? Should I buy a nice name brand exhaust? Resonators? I'm lost at this moment, any suggestions...

I want to get my car exhaust system done But do i need to buy test pipes or could i keep it stock? here is the setup i bought (flowmaster, res, borla xs muffler dual & then 2.5 exhaust tips) I took the speed culture route! Haha.. but anyways do i need a test pipe? i have a 2014 awd premium
