Not to mention that near any exhaust using N1 style mufflers gets crazy loud. Sounds good whipping through the canyons and trees in the hills or on track but day to day....wooof.

I installed the Gemini on our roadster.. Has a nice "sporty" sound..

NOT all too loud. Not raspy and absolutely NO drone..

Another vote for Gemini. The sound of N1 is too aggressive.

Thumbs up

Just installed a Gemini on my '03 Z... keep in mind I also have K&N drop in, Motordyne Plenum spacer and Crawford High Flow Cats which will effect the overall sound. Never heard the N1 just wanted to give my Gemini experience.

Install:
Everything bolts up very easily, the exhaust has perfect fitment, I didn't have to modify anything. The X-pipe goes over the rear support member and the other pipes fit around my Hotchkis sway bars, so nothing had to come off. The exhaust flanges have oblong holes which allows for some wiggle room when aligning everything. The hardest part is removing the old exhaust due to rusty bolts (had to cut two off) and the stock exhaust hangers aren't easy to reach due to their location. To make life easier I removed my tow hook and driver's side hanger mount and then I could slide the stock muffler off sideways. The rear bumper will not allow you to slide the exhaust backwards which is obvious direction it should go. When removing the old parts you can tell there is some weight savings as the stock muffler in particular is heavy in comparison. The Gemini is a complete kit with all bolts and gaskets EXCEPT the ones to the cats, so be prepared to replace those with new bits. The tips mount via clamps, I got the stainless rolled versions to maintain a clean stock look.

The exhaust did smoke a little on first drive as oil inside from the manufacturing process burned off. I'm only on day two of driving it and it still smells a little too.

Sound:
The Gemini is plenty loud enough for my tastes as is. And it drones somewhat to me. The sound is louder and deeper then stock. The real difference is the car now has 3 distinct tones: cruising or steady throttle, on throttle (acceleration) and off throttle (between shifts). You can really tell how much load the engine is under as the exhaust note changes pitch with any adjustment to throttle position. It sounds really good coming off throttle with a nice little burble or rumble. Its not a V8 but has that kind of quality to it. Under hard throttle it sounds impressive, roaring as RPM climbs. I've yet to full wind it out but low to mid (2 to 4K) RPMs have a distinct, agreesive note now. Cruising at 3K I get some drone, but its mostly just louder then stock, basically its the VQ sound just amplified. Overall I'd say the sound is mellow, its not raspy nor is it rough. At idle is not bad just a touch louder, thus I'm glad I've got an aftermarket audio system with an amp and subwoofer plus some sound deading to over come it. Since the Z is already a loud car adding this exhaust really makes you notice it. I can't imagine having anything louder )like test pipes) for a daily driver as that would drive me nuts. The sound quality is pretty much inline with my expectations based on reviews on this forum and YouTube videos, but the in car volume is higher then expected. So I'll likely put some more sound deading in the hatch area and I bet some high temp Dynamat on the rear heat shield would help tone things down.
