How is the disturbing noise you were talking about earlier? Was this fixed by the fine tune?
Do you mean the plugs gave you 100hp more over stock? or the headers + tune?
What does these plugs do exactly?

The noise is completely gone. It was a fitment issue. The headers were rubbing on the driver side. That's been fixed. My H-Pipe still bumps something now and then so they are going to lock it up tighter when I bring it back.
When you are increasing the power of your car by 100hp - meaning headers + tune + intake.... it's good to drop in colder plugs. Got mine from Weistec for about $100.

H-Pipe did well for you. I have a feeling you would be a tad bit better with an x-pipe. Not necessarily enough to warrant 10whp or nothing that extreme, but you would probably gain 5-6WHP through the band.
Guys with your same mods see 480-490whp on DynoJets so you're right on par.

Don't want to sacrifice sound with the X. The performance difference may not be worth the cost either at this point. Car sounds bad *** and I'm close to 490whp anyways. This should go to show that X, H, or straight really doesn't matter with headers.
X's give more peak HP, H's give more torque. But it also matters where the X and where the H are on the pipe. My H is really high up on the pipe.....I mean..... it's pretty X'y. lol jk

well it could fit better..... there's a bit of a leak by the resonator section of the H.... passenger side. It also rattles around quiet a bit. notice the renntech part for sale on page 1 how it has a rubber thingy to stop it from banging that bar in my picture? this thing needs one of those. pushing it up doesn't seem to do anything. thing just doesn't want to not touch that bar.

Check the doughnut gasket it has been. Known to do that. I replaced mine.
The rent tech pipe has a rubber stopper, I had mine made so that you don't need it ( hence more angle it has ). You are the 1st to do this mod so there is defiantly a learning curve. I will take your input and make one tweaked for headers. But try the doughnut gasket for the leak that part has been known to leak and shift once it's removed at times. It also moves due to the gasket I think you will eliminate that issue once you swap it out.

Just swapped the h pipe for the 3" mbh mids and x pipe.
Most noticeable difference is less snarl / rasp. Still no drone. Louder sound that's more even.
I like the sound of the h better. Can't really feel a power difference but there's definitely no more rattling since I removed that cross bar. That thing was driving me nuts.

You kept the resonator?
