I've been lurking on this sight since April when I bought my '05 OB Coupe AT w/ sport package, "19 rays and nav, love it by the way, trying to determine which mods to do first. I want to thank everyone for all the great info on this site, it really has been a big help. I have read countless threads and learned a great deal.

I completed my first mods today! Installed JDM clear corners and Halo super white LEDs in map, doors, license plate, trunk, clearance strip and corners. Also debadged the back except for INFINITI.

After reading all the threads and once the weather gets warmer, I think I know what mods are coming next. But I'm still considering which, if any, cat back.
1) Stillen air box and OEM Z-tube
2) MD 5/16 Copper Iso Thermal plenum spacer
3) Osiris Tune
4) Ichiba V2 Spacers 20/25mm
5) Stillen Strut Bar, it fits over spacer and engine cover
6) Cat back - I love the sound of OEM exhaust, but wouldn't mind a little deeper note, minimal gains I know, and NO RASP. From what I've read FI may be a good choice.

If anyone has any input on the cat back it would be much appreciated.

Once the weather turns and I complete the mods, looking forward to attending meets up in North Jersey. I'm in Morristown.

Thanks again for everyone's informative posts!

Since you have an AT, you may also want to consider one of my custom grounding kits.

PM me if you are interested.

stillen bar doesn't fit over anything.. !! my friend bought my stillen bar, and it wouldn't fit without some washers or something. he had a 5/16 spacer.. i know it claims it fits, but his wouldn't..???? it definitely will not fit the engine cover..

Get the GT Spec strut bar instead of the Stillen. Fits over the engine cover and a 5/16" spacer. Also looks great!!

Riverside Infiniti has great prices on these as well.

Thanks for the info! They claim it does on the web site but I've never tried it or seen it.

Thanks! Does look good! I'll probably grab that instead.

I will consider it. Thanks for the info.

recommend installing the exhaust before your tune.

how muc are they selling the GT Spec strut bar for?

^ IIRC $180ish

not bad at all

I paid $185 shipped to Texas.

Do not get the stillen strut bar, if you want a front strut bar get the GTSpec. sway bars will improve handling much more than a strut bar alone would. i recommend MotorDyne sway bars

Fast Intentions is a great exhaust, also look into the MotorDyne exhaust

Yeah get the exhaust before the tune for best results.

I know most ppl here dont like the TS Pro-1 catback but there was one on the highway next to me today and I almost crashed my car trying to look at what made the noise. It was insane!

I would normally wait for the tune once I completed all the mods, but my understanding is that the Osiris package from UpRev comes with three e-tunes after the initial tune. So once I install the exhaust they can send the software for the added mod, as one of the three e-tunes.

Thanks, I'll take a look at the TS Pro-1.
