Its time to change the tone of your 350Z. We all know how sweet the stock 350Z Exhaust sounds when the pedal is pushed to the floor, but want to change the look of the exhaust system. Lets look at our options.

There are many makers of exhaust systems for the 350Z. NISMO, 5Zigen, APEXi, Amuse, ARC, Borla, DC Sports, Fujitsubo, GReddy, HKS, Injen, Invidia, JIC, Magnaflow, Power Enterprise, Stillen, Tanabe and Veilside... (Just to name a few). How do you know what is rite for you?

Cat Back / Y-Pipe Back / Axle Back? Whats the difference?

In the exhaust system of most cars these days, they are structured like this. Exhaust Header, Catalytic Converter, Pipe, Muffler. On the 350Z we have 2 headers off the cylinder heads. 2 Catalytic Converters off each Header. a Y-Pipe that joins the 2 catalytic converters to 1 pipe, a Mid Pipe and finally to the muffler which splits into two tips.

A Cat-Back exhaust system replaces everything from the Cats and back. It does not replace the cats, but from directly behind them.

A Y-Pipe back exhaust replaces everything from the exit of the Y-Pipe.

Axle Back replaces everything from the rear muffler back.

The only Axle Back exhaust for the 350Z is the GReddy SPII Sports Muffler. This gives a weight reduction as well as add a new look to your 350Z with its large polished stainless steel canister and rolled exhaust tips. The SPII also opens up the sound of your 350Z while making the tone deeper in pitch.

Some Y-Pipe back exhausts are Fujitsubo, JIC, Veilside, Tanabe etc... These exhausts can be used with any Y-Pipes which are also sold seperately.

NISMO, HKS, INJEN, STILLEN, and GReddy make full cat-back exhaust systems. GReddy, HKS, and Stillen's exhaust systems are true dual system where the piping from one side of the exhaust system does not merge with the other (unless a X pipe or H pipe is in place).

JIC, Tanabe, Fujitsubo and NISMO offer Y-Pipes seperately that can be used with any Y-Pipe back exhaust or even used in different combination with any Cat-Back exhaust that uses a Y-Pipe.

Lets look at materials of the exhaust system. Most exhaust systems today are made from Stainless Steel. This material will not corrode from salty air or salt on the roads. Stainless Steel is also very durable and can take abuse. Some exhaust manufacturer's are making systems out of Titanium. Titanium exhaust systems are a fraction of the weight of a stainless steel exhaust but are double or tripple the price. A style for exhaust's is a "Burnt Titanium Tip" which gives a special look to your exhaust system.

The NISMO Exhaust fits beautifully with the 350Z. It is a full Cat-Back exhaust with Y-Pipe structure. Its tone is like stock but louder and fuller. Its tips are angled up and flow with the rear of the 350Z. This exhaust also offers a 10lbs weight reduction over stock and is fully covered under NISSAN Warranty for 1year 12000 miles.

failed to talk about .. h pipe.. and x pipe... or size of tubing, exhaust tempatures, turbulance, boundary layers, resonators, type of silencing agents...
