Default Inspired by 18psi...My Exhaust

To match my 3" downpipe, I needed a 3" exhaust...

One 2 bolt 3" universal exhaust flange
4' of 3" 16 guage aluminized steel
1x 45 on a 4" radius
1x 90 on a 4" radius
1x 7" magnaflow round
1x stainless 90 on 4" radius

Put all of these together and what do you get?

Yeah, I'll be sure and check my coolant lines...Fingers crossed. Turned out pretty well for my first exhaust I think. I wanted the tip pointed down a little, It does look a little odd right now, but I think when it's on the ground it will look just right. Should flow great... I'll get vids when I start the car, should be in the next day or two. First time starting it with the turbo, still gotta reflash the MS and install the IAT.

Same muffler I used in my 3" system but I have a big resonator. How does that sound without a resonator?

mainly how loud is it? Less noise = less attention from cops.

Well, this may be my first exhaust, but I have worked in a fab shop... It's not too loud for my taste. I'm waiting on a heater hose and some heat sheathing, but when I get those in I'll take some vids and post them. Should be next week some time. Then off to the dyno! (fingers crossed)
