Invidia Gemini's. Why? Looks, sound, quality, cost. I went with the Ti rolled tips.

Check out my thread on here. Search under advanced, titles, "My ongoing Invidia review", or something like that. Don't have time to search now, sorry. I have sound and video clips galore on there. Not all under WOT either...

I went with HKS because of the JDM Quality and lower car friendly. The exhaust sound is great with HFC, not to mention the power gain. It’s quiet and civilizes in the cabin during cruising so you can take a long ride, but comes alive liked a beast when you gas it.

3" stainless Y and muffler delete pipes. Very cost effective, the sound is amazing and always easy to change up.

I am interested in the TopSpeed setup mainly because it seems to sound nice and still be easy on the wallet.

Invidia gemini. It has the added benefit of being relatively inexpensive, but I chose it because I felt it had the best sound of any aftermarket system. Not too loud, but adds some throatiness, and matches the sound of the Z to it's looks.

Thanks a lot for all the suggestions, i will look into it and do more research.

greatly appreciate the help :tiphat:

i would suggest Ark. thats my fav so far. Amazing sound and looks.

actually i was thinking about getting the ark system as well after seeing pics of it. I do agree it looks amazing on a Z, but i havent found a good sound clip that gave me the urge to get them though.

I've got to agree with daisuke. I put the Ark exhaust on last month. I love the sound; its close to stock at idle and really comes to life at about 3,000 RPMs. I really like the looks of the Ark exhaust too, it looks really aggressive. The only thing I'm not a big fan of is how low it sits, but I think I can make some quick adjustments the next time I get the car up.

what do you mean by the way it sits? are the tips not level?

Greddy tic exhaust. Total beast. No clearance Issues and makes a statement

theres a whole thread in the intake area about the ARK.

No, the tips line up nicely. The mufflers and right in front of the mufflers hang low.

CNT Racing with test pipes. I was going to get the Fast Intentions exhaust, but I watched a few videos of the CNT abd a deal came along and I pulled the trigger. This Exhaust is similar to the Ark. It is docile when just cruising, but when you put your foot down, the power and sound come alive.
Therer is a metal cover on the back passenger side that needs to be modified for the exhaust to fit. My guess is the FI needs the same mod.
