The FI exhaust will fit; but you will need quad tips to fill the opening and look "right". Any exhaust shop can chop your current tips and weld on new ones to fit perfect (not nearly as intimidating as it sounds). Quad 4" tips fill the Zele rear perfect. And yes, 2.5" piping was used on the red Z above.

To the OP as I am one of the only ones in the US with a real kit. The Product offerings on the market will not fit an authentic kit... I know because I have the schematics from Zele Japan on their exhaust and the bumper. Their exhaust tips are oval and not round. If you are buying an authentic kit PM me and I will share the schematic measurements with you.

If you are getting a replica or knock off kit then yes their are some options on the market. What most have done is had a custom exhaust made for the kit.

I am running a custom exhaust from GTM for mine... I also had my bumper modified to accommodate quad 4.5" GTR Agency Power tips (Discontinued).

Very nice... Thanks for the info... I have the Fly1 ZL rep kit w/carbon fiber insert... however, I probably will pick up the carbon fiber spoiler later from Zele.

My exhaust is getting worked on tomorrow. I will post pics of quad 4" burnt tips.

cool, thanks man... I contacted Tony and he sells the 4.5" resonated tips for $125 ea and $15 for shipping. I was told that it would be a tight fit (that's what she said)... I will measure the exhaust opening when the body kit arrive.

I wasn't able to get the tips installed because the shop forgot to order stainless piping so I have to wait until May 2nd now. It's a tight fit for piping. My estimate is $700 for stainless, TIG welded and they're going to join two pipes into one for me. I bought AAM 4" titanium burnt tips.

$700? sound kind of high from what other said it cost ($150) them for the shop to fabricate...

I think others are doing raw steel and branching it out. I want a cleaner look. I was also quoted $350 for raw steel. I could get it done for cheaper, but I want it to look right. I'm going to get a quote for stainless from another shop, but I think it'll be around $500 because of the labor involved.

edit:
The shop that quoted me $700 refused to "hack" the job and wanted to make a stainless ypipe that goes into one and then into the fast intentions canister so the tips are functional.

good luck and let me know how it goes... Can you take a pic of the rear ZL bumper installed with the FI exhaust before it is modified? THANKS!!!

I'll get some pics when she's done. Hopefully soon -- it's burning a hole in my wallet. I did NOT expect the costs of everything that is happening.

Have you tired R & D Custom Exhaust in North Billerica. They did some work for me a year ago the work was A+ and the price was even better. Was referred to them by another car guy I know.

I called them for a quote, I should check them out. They do stainless too, right?

edit:

I called them to re-do my whole exhaust. I never got quote just to do tips.

I think they do stainless , the modded my coule exhaust to fit my sedan . Split the rear mufflers and made new piping :)

Yep, I definitely got to get quad tips ASAP... It looks like I can fit two 4.5" resonated exhaust tip from FI easily in the opening... why are people saying to go with 4" quad tips???
