Long Tube Headers

Your going to have to get a tune after you install these. That's a drastic change in the exhaust setup and the ECU is not tuned for that. You will probably not notice any difference in power without a tune. You might even feel less.

I know that I'm going to go full bolt on then a tune. just curious as to what would be the best. I've seen good things about all just that fast intentions loses some power on the top end. also saw that motordynes are actually mid length as you can have test pipes/hfc. and I've seen nothing but great things about ppe just that they're pricey compared to other two. I guess I'm trying to figure out if I should go ppe or motordyne, because there's a good price difference in the two even if I bought test pipes for the motordyne.

Motordyne for the beautiful pipes and no rasp.

Mine rasps. I've got the Motordyne with HFCs and Borla CBE and it rasps at about 3k. At least I assume that's what you are speaking of.

If you go with Motordyne, you'll have to extend the O2 sensor cables. I had mine done at Dynosty and they extended them. Not sure exactly how they did it, because you can't solder the wires.

I love them though. Sounds REALLY awesome when you go through a tunnel.

I have same MD but with Helmholtz res, and the note is deep, it is mated with Fast intention cbe with 12" res.

And agree on the o2 sensors, I bought 20 guages automotive wires and my mechanic soldered them to the sensors and it worked well.


As far as quality, I can assure both MD and FI are high quality.

What gains did you see from the LT's? Pretty sure I'd end up going motordyne. Is ceramic coating worth it?

You really don't need a tune unless you do all 3. That is a cai, lth's, and cbe. The ECU will handle lth's by their self and with one other breathing mod. 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. Solder the wire extension together for the O2 sensors. Don't cheap out here.

Been there, done that!

Not sure of gains, as I didn't do before and after runs (installation and tuning were in different places). Also, didn't coated them.

But I felt a lot of torque in low-mid rpm.
