whats the most basic mods for our cars?

Mine's FI resonated Test Pipes & 18" resonated mid pipe & polished stainless muffler's.
You want louder-go non resonated.

Test pipes flow more freely and will give more top-end hp that stock cats or hi flow cats. Definitely the way to go if you aren't concerned with emissions.

I use Berk hi flow cats so I can pass VA inspection without being shady, and they provide pretty decent power over the OEM cats. I just got my 7at tuned at just under 319 whp with the Berks. I probably could have gotten a few more hp out of test pipes, but i like the result.

For test pipes, consider the following
1. Internal diameter: some test pipes (I want to say berk and invidia) have an internal diameter of 60mm (2.36"). If you pick up a 2.5" cbe, you'll see the best result from test pipes with the same 2.5" diameter (like fast intentions or AAM). However, I haven't seen this explicitly tested for power differences.

2. Resonated v non-resonated - Resonated test pipes can cut down a bit on the drone of your exhaust, but are more expensive. At another level, ART pipes have a separate chamber that branches off the pipe and makes the sound much better (in my opinion), but these are the most expensive.

3. o2 bungs - extended o2 bungs reduce the chance of throwing a CEL. This would be a moot point if you get it tuned. You can also pick up bung extenders from vendors like Z

For hi flow cats, look at the internal diameter, and the cell count. The lower the cell count, the better your exhaust will flow. Common cell counts are 200 (Berk, AAM), or 300 (Fast Intentions).

If you want louder, definitely go non-resonated.

So test pipes would be replacing the cats then correct? Im not too worried about emissions as michigan doesnt test for that(thankfully lol)

Yep, test pipes would replace the cats

I misued the term axleback. ( I was referring to a vehicle with a front axle) lol. I have a full exhaust not axleback.

So since i live in a state that doesnt check emissions, do you think a fi cbe and art non resonated tps would be a good setup?

Yes. The only drawback to test pipes are emissions, loudness, and a CEL. Like u said emissions isn't a problem, and if you want a loud car then go for it. (It'll sound great!) After you get a tune you can clear the CEL forever.

Test pipes will yield a bit more power than high flow cats. The reason I chose high flow cats is I didn't want my car to be loud bc my neighbors would hate me and it kinda gets annoying imo.(I had a straight piped 300zx lololol never again) Plus I need to pass emissions.

Well i dont want to be obnoxiously loud but i want it to sound mean at the same time, maybe ill try resonated tps at first snd if i dont like them ill sell those and get non resonated..but still going back and forth between motordyne and fi cbe

Unsure about motordyne; but if you go FI,,,be prepared to wait a while for them to be made...all of their exhaust system's are custom built & do fit well.

Virtually no wait on my motordyne when i ordered it through Z1. I think The MD warehouse keeps some in stock.

If you plan on going with a low ride height, or if you have any extra modifications in the rear area (like the extended diff cover and rear anti-roll bar) the clearance is a bit limited with 3 inch piping. The area around my rear diff is crowded.

Well i dont want something thats gonna be hanging low as i have to dodge potholes every 5 ft when i drive around here, but i did also plan on lowering my z a few inches

Looks like i cant really go wrong with either the fi or md cbe. I dont plan on doing a whole lot of modding to the rear end(as im not sure what mods are available)

How long did you have to wait on yours?

jchammond

mine took the full 12-weeks....they may be quicker on the turn-a-round now.
ordered 1/12/16,,,received 4/14/16 (13-weeks)
Love it & worth the wait.
