Alright, great to know, thanks....

Anyone have any opinions on the Greddy EVO2 exhaust, I am thinking of going that route with a y-pipe.

Jim,
That's very interesting 'custom' exhaust. Just a few questions:

1. What kind of muffler are those?
2. Have you dyno'd it? or at least what's the butt version tell you?
3. How's the noise level?

Thanks,
Clint

No, my wording probably wasn't the best choice, but what I meant to say was that an aftermarket Y-pipe such as a JIC, Japtrix, NFC, etc. on an otherwise stock 350z/G35 will usually gain around 5-6 rwhp as shown by dynos. That is why I just bought myself a NFC Y-pipe for my G.

Thanks Clint, I had a fun time creating it, nice to accomplish something yourself, well ok I didn't do the welding.

1. Mufflers are Injen SES, I went with them because I got to here the Injen system in person and I love it's sound quality.

2. No, I've never dyno'd the car. The gain's I got are equal to or slightly better to what I got with the Crawford pleneum, I'll go out on a limb and say at least 10hp, butt dyno of course.

3. In a side by side comparo to a sedan with the Stillen TD, the Stillen was actually deeper at idle. Using part throttle, the cat's to give out a rasp at about 3500rpms to 4500rpms. At full throttle the system does not have any raspiness and it's IMO just loud enough to make me happy, but I would not want it any louder. Getting back to the Stillen, I heard a sedan take off full throttle with the Stillen, it did not sound very loud. IMO, my system is much louder at full throttle then what I heard. On the drone issue, I have less of it then when I had the Magnaflow resonator on with the oem system, even then it did not bother me. In any event, I wouldn't think a system simular to mine wouldn't be a good idea for someone concerned about noise or sound level's. And since I run with the silencer's in place, nothing really can be done to quite it down.
