r0shiro 3IS Build Thread by r0shiro

3 minute(s) of a 47 minute read

This is an intake made for this engine (3.5L) but fitted for the engine bay and wiring of the 2IS so there are some clips here and there that are no longer "clipped" down and a hose needed to be bent in a different direction versus the stock direction. Other than those caveats, this was a fairly simple mod. On a moderate to aggressive acceleration (350 f-sport) it adds a massive growl to the the exhaust. The growl mellows out when the speed plateaus but chimes in again when you accelerate even in the higher gears. i will be posting a DYI later tonight of the installation. enjoy these two in the meantime. =)

Hello CL!

I've been privileged enough to be part of the R&D for the PTS-Joe Z Exhaust for the 3IS. Here are a few pics and progress points I can share at the moment. More to come I promise!!

First off, we all know the care and professionalism JoeZ takes into his projects but I can't say enough how impressed I was with the knowledge and professionalism of the PTS staff and their engineers. This is going to be a solid product. 

pics...

1) the angrypanda on the lift

2)a shot of rear to front with the stock exhaust on

3)rear to front shot - no axle back, no mid-pipe

4)front to rear shot - no axle back, no mid-pipe

5) stock exhaust

This system seems identical to the one on the 4GS. The biggest difference (and the most obvious) is the length of the entire catback. The 3IS seems to be an inch or so shorter than the one on the 4GS. This was the first of many R&D sessions and while I can't say much...i can say that it will sound amazing. I'll keep y'all posted 

Added the TRD push-to-start button. A big thank you to Nigel-JDMparts and JoeZ. Contact either for pricing. =) I will post a DIY soon.
