Default Axle back exhaust help

Hey guys, looking for help trying to upgrade my 2015 Q50S stock exhaust (axle-back)... also my first mod. Are there any exhaust cheaper than $600 that are worth looking into? I love how the helmholtz sounds but can't justify the cost to the wife. I was looking at the rev9 but saw some posts warning about the type of metal it is and that it will corrode. I live in NY and the car is my daily driver. I don't like muffler delete cause it's too loud for my taste. I like the helmholtz cause it's loud when it needs to be. Please advise, I'm new to this and don't know much. (Hopefully the cheaper it is I can add diffuser and splitter&#x1f60a

Oh god, another one that needs approval from the wife. I would sell her car and use the money to drop a SuperCharger on your Q. Trust me, she will respect you more after. I'd also go with a loud exhaust, that way when she complains about the money you've spent you can just floor it and drown out the noise. I've had 3 successful marriages I know of what I speak.

lol, I'm just kidding I haven't been married 3 times. I always have to bust balls when someone mentions that the wife won't like it, I'm just having fun with you and I'm bored at work. Other than that I have nothing to contribute. Some serious modders on this forum will chime in with useful knowledge shortly.

I'm actually looking at the Infiniti sport exhaust myself, but it's over $600.

Screw it! Put a full FI exhaust system in it for $3400. It's fairly quiet except cold start. She may not notice it. But you get 2 MPG and a good amount of power!
How long have you been married? Lol. When you get things you want to just divide by 2 (or more). Worked for me!

There is a guy in here selling his Helmholtz for $450 I think.

He's in the Q60 forum.

Maybe I'm missing something but Rev9 doesn't have exhausts for the Q50 from what I can see on their website.

I didn't check their site but they have axle back exhaust going for $350-400. It's called Flowmaxx, CB-1004

I of course need to run everything expensive by the wife (and vise versa). But she has been incredibly supportive of modding the Q50 so far. I think a lot of it is because I finally agreed to sell a rental property we had. I wanted to keep it as a rental. She begged me to sell it. This went on for years. I caved. We cleared $60k after fees and taxes.

Personally, I wouldn't buy an exhaust unless it is made of T304 SS or better. That Flowmaxx is made of T201 SS. While T201 SS has a higher tensile strength than T304 SS and can be made thinner, it has a lot lower nickel content than T304 SS. As a result, it's corrosion resistance isn't good and when exposed to road salts it will eventually corrode. T201 SS is mainly used for making cookware, cooking utensils, sinks and other restaurant equipment. It is a lot cheaper than T304 SS because of its low nickel content.
