350Z / G35 Coupe True-Dual LS Swap Exhaust System by Kooks

350Z / G35 Coupe True-Dual LS Swap Exhaust System by Kooks

$ 1,999.95

These exhaust systems are made exclusively for LOJ Conversions by renowned header and exhaust manufacturer Kooks! You simply will not find a finer quality exhaust system anywhere! 

LOJ Conversions 350z / G35 Coupe True-Dual LS Swap Exhaust Systems are constructed of 100% USA Sourced T304 Aircraft Quality Stainless Steel, with mandrel bent 2.5” or 3.0" ID Piping. 

All of the exhaust systems utilize 3" piping from the headers to the X-Pipe. The piping after the X can be either 3" throughout or 2.5". The 3" front pipes are available with or without catalytic converters.

The 2.5" systems are quieter and less susceptible to drone while cruising on the highway. We recommend the 2.5" systems for the customers looking for a quiet daily driver experience that barks at wide open throttle. At less than 600WHP, the 2.5" system sacrifices nothing over the 3" system.

For those customers looking for more noise, the 3" system is the answer. No one will second guess what is under the hood of your ride with one of these systems installed. The high flow nature of the 3" piping makes them good for over 1000WHP. 

The exhaust tips are slip-fit and available in both Polished Stainless Steel or Satin Black. 

In order to maintain symmetry and proper ground clearance, LOJ designed these systems to work with a double-hump rear swaybar as opposed to snaking around the factory single hump swaybar. Below you will find a list of OEM swaybars, diameters, and applications that can be used on both the 350Z and G35 to clear this exhaust system. All of these swaybars can be purchased very inexpesively from used parts sellers online. In some cases, they can be had for as little as $75 shipped. LOJ felt this small investment was worthwhile to achieve a better fitting, no-compromises, true-dual exhaust system. Make sure that whichever swaybar you choose comes with the D-Brackets and Bushings!

* LOJ Recommends this swaybar for the closest driving characteristics to the stock swaybar.

** This M45 swaybar can physically be bolted into the car, but will not clear the rear exhaust hangars without customization. We do not recommend this option unless you have fabrication skills to facilitate installation.

 

NOTE: These exhaust systems are specifically designed to work with our LS Swap Headers and engine placement using the LOJ Conversions LS Swap Kit. LOJ can not and will not guarantee fitment with any other headers or swap kits on the market!
