The ISR Performance Y - pipe for 350z and G35 is a top - notch exhaust component. It uses 2.5 - inch stainless steel pipes with bellowed flex sections. These run from the 2 - bolt catalytic converter flanges all the way back to the high - performance velocity merge. After the merge, the pipe steps up to 3 - inch stainless piping leading to the rear 3 - inch exhaust flange. There's also an integrated dimpled gusset plate that connects the two runners, boosting strength and rigidity. This Y - pipe doesn't fit the G35 X. In the box, you'll get 1 Y - pipe for 350z/G35, 2 2 - bolt 2.5 - inch exhaust gaskets, 1 2 - bolt 3 - inch exhaust gasket, 6 bolts, and 6 nuts. It's designed to offer the best exhaust tone, good ground clearance, and high performance at an affordable price. Note that the 2007 G35 sedan has an HR engine and a G37 body style, so you should use a 370Z y - pipe instead.
Using the ISR Performance Y - pipe is quite straightforward. First, make sure your vehicle is a 350Z or G35 (not a G35 X). If you have a 2007 G35 sedan, it has an HR engine and G37 body style, so this Y - pipe won't fit; you'll need a 370Z y - pipe. When installing, use the provided 2 2 - bolt 2.5 - inch exhaust gaskets, 1 2 - bolt 3 - inch exhaust gasket, 6 bolts, and 6 nuts. Simply attach the Y - pipe from the 2 - bolt catalytic converter flanges to the rear exhaust flange. As for maintenance, regularly check the bolts and nuts to make sure they're tight. If you notice any rattling or strange noises, it might be a sign that the connections need tightening. Also, keep an eye on the stainless steel pipes for any signs of corrosion. If you live in an area with harsh weather or road salt, you may want to clean the pipes more frequently to prevent rust. Overall, with proper installation and maintenance, this Y - pipe will give you great exhaust performance and a nice tone for a long time.
