Features an integrated dimpled gusset plate tying the two runners together for added strength.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eThe Y-pipe is the section of exhaust that merges the two banks of the VQ35DE V6 into a single pipe before the catback. The factory Y-pipe is a flow restriction and a known weight-saving opportunity. The ISR Y-pipe replaces it with mandrel-bent 2.5 inch stainless runners that feed a velocity merge before stepping up to 3 inch piping at the catback connection. The velocity merge geometry is designed to maintain exhaust pulse separation longer than a generic Y-pipe, which produces better tone and reduced back pressure.\u003c\/p\u003e\n\n\u003cp\u003eBellowed flex sections at the front absorb engine movement and thermal expansion. The integrated dimpled gusset plate stiffens the structure and prevents flex at the merge.\u003c\/p\u003e\n\n\u003ch3\u003ePairs Well With\u003c\/h3\u003e\n\u003cp\u003eDesigned to work with stock or aftermarket downpipes and any 350Z \/ G35 catback exhaust. Pairs particularly well with the ISR GT Single or EP Dual catback systems for a complete ISR exhaust path. Also bolts up to LS-swapped 350Z builds using ISR HGC LS swap headers (IS-SSHD-350LS), turning this Y-pipe into the LS-swap mid-pipe for a clean install path.\u003c\/p\u003e\n\n\u003ch3\u003eCritical Fitment\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eRWD ONLY.\u003c\/strong\u003e Will NOT fit on AWD G35X models.
