Hey guys i know I haven't posted in a long time, i've been pretty busy lately, but im kind of in a pickle. I'm doing the ISR mod to my runner as we speak but i just wanted to clarify on some thing. I took the silencer out and bought a 3" in diameter ABS pipe. The 3" pipe is bigger than the old silencer, so big it actually fits over the two pipes leading into it. My question is, can i keep it like this or do I need to get a smaller pipe? and with the vacum hose that connects to my FPR, can i hook it into the nipple on the intake manifold? Here are some pictures of everything.

Also here is the tube, can i hook the FPR into this nipple?



Thank You very much

Well nevermind, I went and got a 2.5in pipe to replace it and it works great. I reset the ECU to get the correct air/fuel ratios and should be set. Ill post pics up later.

Hey guys, as I said i would post up some pics so here they are. If anyone has questions about the mod feel free to ask. So far I really like it. Seems like the throttle is much more punchier and the sound is great.
Here it is in place:

This is what i did with the vacuum tube. I took of the nipple on the intake manifold, and put the hose to the FPR on to there:

And here is just another pic from the side:

Intake silencer removal. dont know if it actually works or not. but its supposed to increase ariflow on the intake. from what i hear it makes it louder too. i have no first hand experience on it though.

Yeah it's the Intake Silencer Removal, it takes out the resonator that sits in between your air box and throttle body. It does make it louder, and the throttle seems to be more peppy.
