My mechanic is extremely knowledgeable when it comes to Zs. From what he's told me, if you're looking for legit hp gains, HFCs and a good cat back system are the best starting point followed by new software and tuning. I was leaning towards doing a CAI abut after talking with him, I'm convinced that it's more of a cherry on top than a priority mod. From what I've been told, the factory air intake is quite respectable. With tuning, a CAI will net you 5 hp at best. Prioritize the exhaust system, and branch out from there. If you're looking for a solid cat back system, Motordyne is the way to go.

Probably won't happen without tune!
270whp w/K&N Drop-in's
added FI TP's & Exhaust
added Z1 cai
drove 500+ miles & ran better,,,definite difference.
Got on Dyno....290whp.....after tune 309whp & felt like a different car.
Don't leave out the tune-just as/or more important than your bolt-on's!

I Disagree-depends on which one you got!https://uploads.tapatalk-cdn.com/201...c065e27fb0.jpg

I was actually planning on waiting til i had mostly everything ordered(cbe/cai) and install everything at once, rather than doing the exhaust and cai at different times. I was also looking at the motordyne exhaust but 2k for an exhaust is kinda pricey to me, not out of the question but definitely wanna see whats out there thats just as good for a bit cheaper.

Im going with stillen gen 3 cais, they have the best gains from what ive seen, as for exhaust i dont know much about test pipes so, whats the advantage of having them? And depending on if i can find aomeone reputable around my area to tune my car i will

Pic shown is with up-graded version of Z1's cai,,,,,additional 5-6rwhp.
I added this after my first tune.
Using the stillen will move your maf's & unsure how it will effect your afr....test pipe's are probably the biggest bolt on gainer of them all.
Factor in a Tune-you & your car won't regret it!

For the exhaust after the cats,, think about where you're going to be spending the most time in the rev range. An x-pipe design may sacrifice some low-end torque, but will open up more potential hp at the top-end. Alternatively, an h-pipe can offer more low-end torque at the cost of top-end potential. Our cars aren't known for low-end torque, so a lot of people go with an x-pipe.

My car is my daily driver, so I'm liking the low-end that the AAM h pipe gives me.

The factory cats are a huge bottleneck for exhaust flow. Test pipes are the best way to open up that flow, but are much louder and can have a strong smell. Would recommend getting a tune if you go with test pipes as you'll lose some low-end power and will probably trigger the SES light.

i'll dig up a video from the strip 0-120.

What makes test pipes better than others?

listen to mine in video

Not bad i was looking at fi cbe and it looks like i might either go with fi or motordyne, not sure what test pipes though. Also going with stillen gen e longtube cais, i think ill see the most gains from them, unless theres others that are as good with proven results
