^Doesn't MD have different version spacers? (since that link was posted in 2005)
EDIT: I didn't read the whole thread but the dyno runs in that link were done on different days.

The spacer will improve the overall power band so it is still worth it.

 

You are completely wrong.

 

That was back in 05 with the MD 3/8 spacer. Now they run 5/16 so maybe it changed?? I've always heard nothing but good things about the spacers.

 

as far as y-pipe goes. i have two in mind and which will work better with a stock vq35de set up, nismo y pipe or the hr y pipe? this will be going on an 05 g35

 

umm, 05 6MT = REVUP engine and yes, it is well known a spacer on a revup engine is useless. If you have a revup you'll need to combine the spacer with the MREV2, which is essentially a modified non-revup lower plenum.

If you have a non-revup, then a spacer is well known to add power.

 

any comments on a magnaflow cat back system? i like the sound, anyone know about preformance?

 

So next... should I get wheel spacers, 350z H-Techs, sideskirts, or exhaust?

 

Go low, then exhaust.

 

Hey everyone im new to the forum and just bought a 05 G35 coupe last week and fell in love with it. I already got a pretty good idea about doing some exterior work but im a little stuck on the performance side. I had to buy an automatic cause manuals are really rare and hard to find in my area (plus traffic here is insane) and I was wondering if it was worth modding. I have some money to throw around and wanted to start off with some basics. Any suggestions on which route to take? I'd appreciate any advice!

 

Z tube
5/16 spacer
Art pipes
And whatever cat back exhaust you like

That's pretty much it.

 

Hey everyone, I recently just purchased an 05 MT Coupe and Im almost satisfied but would love a little extra umph. I got about 3 grand to spend. Anything besides the general intakes that would be worthwhile?

 

See my post above.

 

Thanks

 

Thanks this was very useful information for my G35.

 

i'm getting the strafe inven front bumper. the only thing holding me back is deciding whether to get it in fiberglass or polyurethane. anyone have any suggestions?
