Custom vs. aftermarket exhaust
My original plan was to purchase the Motordyne catback, but my buddy whose going to be doing the install wants to do a custom exhaust.
He said he could do an entire custom catback for $500. He kept trying to sway me from the aftermarket exhaust because I was going to be "spending $1.8K for 5-10 extra HP".
How do you guys feel about custom vs. aftermarket?

Good luck getting 80 HP from intake, headers, exhaust and a tune.
A custom fabricated exhaust can be great if it's done by someone who genuinely knows what they are doing. But how certain are you that it will have the same research, quality of materials, workmanship, fit and finish, and aesthetics of the MD system? I'm 99% certain it won't.

Definitely won't be like the motordyne exhaust. I would suggest you take a look at other options too but Motordyne is one of the best exhaust systems for our cars. I would actually take in consideration ARK as well a little cheaper and buy some high flow cats or test pipes. Yes a exhaust won't give many hp gains the hfcs and test pipes will give you the most horsepower gains but not as much like 80hp. I can see you running 350 whp full bolt on with headers

I think I remember hearing that the newer, updated version of the Ark doesn't hang as low as the older model.
It sounds good and looks good though.

Custom is good when you want a low cost exhaust. You won't know how is sounds, how loud it is, or how much power it makes.
Aftermarket (like Stillen, Motordyne, etc) do cost more, but they have many hours of R&D, dyno testing to max gains, and generally better build quality & fitment.
What do you value?

If done right, custom is the way to go IMO. Get a unique sound for an affordable price. Even if there is a HP discrepancy, it will be so minimal you wont notice. Like others have said: Mendrel bent NOT crush bent. Most after market systems are 2.5'' I believe GTHaus is 2.25'' the stock system is 2''. Others can correct me but you can use that info as a reference. I believe the most common I see, that others have mentioned, are: ARk, FI, and Motordyne. All have unique qualities and styles. All sound fantastic and are within $300 of each other pending where you buy. There are also some great systems not mentioned including the Rochester dubbed "Sport" exhaust made by Stillen if going for a moderate sound
The most expensive of those three, according to my records is the Motordyne @ $1,70x.xx. Listen to clips and decide from there. Sedan section has an entire thread dedicated to this...
Lastly, All the bolt-ons in the world will not net you 80 rwhp but I can appreciate your friend dreaming big lol.
