The ISR Performance 350z / G35 Y-pipe utilizes 2.5" stainless steel piping along with bellowed flex sections running from the 2 bolt catalytic converter flanges back to the high performance velocity merge. The Y pipe then steps to 3" stainless piping coming out of the velocity merge to the rear 3" exhaust flange. The Y pipe also features an integrated dimpled gusset plate tying the two individual runners together for increased strength and rigidity.
Does not fit G35 X
What’s in the box:
The ISR Performance Y pipe was designed to provide the best possible exhaust tone, ground clearance, and performance, all at an affordable price!
Fitment Note: 2007 G35 sedan is HR engine, G37 body style. You would want to run a 370Z y pipe.
Outstanding quality, great welds and fitment is perfect. Goes great with my ISR blast pipe exhaust. All the hardware you need is there and install is a breeze.
Horrible sound, close to 3k rpm rasps bad
Direct bolt in very easy to Install took me about a hour.welds on the y pipe are high quality love the stainless steel.
this y pipe made my exhaust slightly louder and deeper than before. i noticed a very slight low end power increase, though that could just be me enjoying the car more. the weld quality looks very good and shipping was crazy fast… thanks iir
Great replacement for the stock y pipe that is prone to exhaust leaks.
Quick, easy, and no issues at all. Gonna be alot of fun installing this thing. 100% recommend this website and product.
Came in perfect condition and a day before expected. Will definitely recommend this site to my buddies. Gives a nice deeper growly note along with my high flow cats
This pipe fit and sounds great. I have the invidia cat back with stock cats on my 2003 350z. It didn’t sound good until I installed this y pipe. It had a “buzz” sound that I didn’t like but when I added this y pipe it got rid of that sound. Now it sounds perfect.
I bought this along with the ISR single exit. i was looking for a replacement part for my OEM y pipe. This piece fits in nicely and makes a great replacement while increasing the depth of the exhaust note. Great bang for the buck
I like it. I have stock headers, "1320"test pipes, "ISR" y-pipe, stock resonator pipe, and a nismo muffler. Its led to a fine note with some pops when red-lined briefly! But theres a rattle near the output of the y-pipe, Might have something to do with the smaller flange on the stock resonator. Might need to find another resonator pipe. Definitely want to keep the resonator thought or els itll be too loud.
