It's called the law of diminishing returns. You out long tubes and tube on a stock Nismo and make 30+who, all of a sudden it seems like a great deal. Add it in to a full bolt on car and make 10, not so much. So the argument doesn't make sense when you actually look into it.

Maybe I am mistaken your audience as my comment but I agree with diminishing returns. LTH which remove the highly restrictive cats does make a nice gain. As far as motordyne intake I lost power with it and instead ported the upper and lower stock manifolds and improved performance over motordyne. I also added cold air intakes and that had a nice gain then added EPS throttle bodies and gained again with better throttle response. My situation is not budget worthy tho. This is my hobby and what I throw away money into :)

I also agree with coating them. Anything to help keep the Z cooler is better. I mean **** we already have to add an oil cooler just to get to the track.

I have the FI LTH, 12" resonators, cbe and G3 cai. The ceramic coating helps keep the heat in the tubes, increasing exhaust velocity. Which is best is a personal choice. They all make about the same gains. You also forgot about the Z1 shorty's. They make about the same power.

Which ever you choose. Remove the O2 sensors first! DO NOT USE an impact gun on them. The right side will take you about 1.5 hours, counting beer breaks. The left side will take you 6+ hours and lots of cussing. It's best to move the manifold and down pipe together as one. This way, you don't have to mess with the demon bolts. :eek: Solder the wire extension together for the O2 sensors. Don't cheap out here.

Been there, done that! :eek:

I'm going to +1 with rusty on the fact that the driver side sucks all the **** not as much space like the passanger side. That side wasn't bad at all. as far as the demon cat bolts i did my headers when i only had 5k ish miles on the car so they came off without too much headache, so i lucked out there. I had an RC hobby shop extend my O2 sensors so didn't have to worry much. I went with fast intentions LTH and wrapped them myself. Yes there is a little bit of rasp but I've learned to get used to it. won't have that issue anymore once my turbos are on:tup:

I'm currently running a Motordyne Shockwave catback w/ Stillen Gen 3 intakes. Motordyne long tube headers is next in line. Still debating whether to go resonated or non resonated. Thoughts?

Resonated will mean less drone in car, I converted from non-res hfc to lth with res, the drone went down with them and the car isn't very noisy at lower speeds, compared to the hfc

Do you have any videos of how your car sounds with the 12" resonator and LTH. Are you the one that had the in car view while at the track?

Yep, that was me. :driving:
