Product Description

The Z1 Nissan 350Z Cat-Back Dual Exhaust combines our most popular dual exhaust with our new Z1 Stainless Steel Y-Pipe into one convenient and well-priced exhaust system.

The Z1 Motorsports M-Spec 350Z Dual Exhaust was designed for the enthusiast looking for a dual exhaust that does not sacrifice power or sound! The race-inspired muffler design produces an exhaust note with a signature growl.

Features include a fully tig welded construction with 16 gauge 304 stainless steel tubing. A 3" main pipe leads to our stepped V Band connection to ensure a positive seal ahead of the two mandrel bent, 2 1/4" sections connecting the Z1 Motorsports resonated mufflers with 4" tips in your choice of straight or slant cut style. 

This exhaust is LOUD, but with the newly included dual stage silencer, the exhaust volume can be changed within minutes with basic hand tools, making early morning escapes to the race track an easy feat to achieve without waking your easily disturbed neighbor.

The Z1 Dual Exhaust weighs only 35.65lbs, approximately 10.53lbs lighter than stock!

High-Velocity Y-Pipe

The Z1 Stainless Steel Y-Pipe included in the Cat-Back exhaust was produced specifically for enthusiasts looking to increase horsepower and torque across the entire powerband while simultaneously improving exhaust note when combined with a full exhaust. Features a special 3-piece design with swedged slip joints, making installation a breeze! 2mm wall thickeness ensures maximum durability while thick laser-cut flanges are utilized to ensure a proper seal with high resistance to warpage overtime.

Mandrel bent primary pipes provide smooth transitions to the large 3'' merge collector. The merge collector increases exhaust gas velocity and improves the scavenging effect. Exhaust scavenging makes an exhaust system more efficient, by improving the scavenging effect of the exhaust you allow for greater exhaust flow resulting in MORE POWER! In addition, an auxiliary exhaust bung is installed in the collector at the rear to allow for easy wideband installation or additional monitoring of exhaust gas temperature.

Please Note: Removal of the EVAP box splash shield and some minor trimming to the rear bumper may be needed for muffler clearance. If this is not done damage to the bumper can occur. 

Features:

  • Stainless Steel Construction for Optimal Corrosion Resistance
  • Mandrel Bent Piping For Maximum Flow
  • 2mm Wall Thickness = Durability!
  • 12mm Thick Mounting Flange
  • Dual Baffle Silencer Included
  • Included Y-Pipe

This system includes:

I went with a Z1 because of their great reputation and I was looking for a specific sound. Fitment was great until the last y-pipe and muffler. In their defense Z1 is very clear that you will need to remove the EVAP splash shield and may need to trim up your bumper, that said... is an understatement. I have an aftermarket bumper so I can't comment as to that but the removal of the EVAP shield is a real issue. Even removed its a tight fit and heat becomes a concern with the lines so close. They should have either designed the thing to fit correctly from go or offer a custom heat shield/splash guard. I just don't get the logic of making it not clear everything, it seems counterintuitive. I've owned a few fun project cars over the years from a 3000gt to a Trans Am and never had a similar issue. It does sound awesome tho... just make it fit properly... I don't get it. You shouldn't have to do squirrely stuff to fit a cat-back. Great sound, great welding, solid construction... underwhelming design.

Sounds great and is a quality exhaust. Went with this instead of buy and dual Tomei and saved myself some money in the long run. No rasp and has a great rumble to the car now vs the stock exhaust. It is loud though so hope you have cool neighbors.

sounds really good, not to loud but not quiet. one thing is be prepared to cut your bumper because it does not fit flush, unless you spend hours adjusting fitment.

Honestly not bad for the price and it sounds great in my opinion, I do still have cats. Only real problems I’ve had with mine is being so low and scraping because of how the straight pip to y exhaust setup is but it seems manageable. Also it might not line up completely straight first try so honestly I hope you don’t mind melting a lil bit of bumper lol.

Okay, I'm impressed! I had someone else, exhaust professionals, do the install. Only took them about an hour because they wanted to do it right. We were all pleased that everything was there(I've bought from Ikea before) and that it all went together so easily. I've been driving the car for 2 weeks now and I like it! I run with the silencers in because...Round Rock, Texas. I'll get more comfortable and start removing the baffles soon, but people need to get used to me. It's plenty loud already. The car idles at 500-750 rpms, steady. Smooth acceleration, no backfires (good engineering! ) I cringe at the cheap systems that pop and bang when you accel. or back off. This thing is SMOOTH! I say 4.75 outta 5 stars. Lost .25 because it pointed out my cheap aftermarket camshaft position sensor and I had to go back to OEM. I hate being called cheap by my car!

Hello, For those of you shopping for exhaust for your 350Z,Z33 look no further. This is the one that all the others are trying to imitate. Looks and sounds very aggressive. Medium to difficult bolt on cat-back solo install on jack stands. Very easy with buddy and lift! Thanks Z1 will definitely look to Z1 for future mods.

Sound and material quality is excellent, but I am having fitment issues even with an OEM bumper, needed some additional bending and cutting to get it to fit correctly.

Exhaust is well put together and sounds good, welds and construction look great, but I'm not at all a fan of how far it sticks out from under my bumper and I will unfortunately be paying a shop to modify the mufflers and piping to make it fit better here soon
