Here's my current setup:

MD 5/16" Spacer
SxExCx Grounding Kit
Z-Tube
Amsoil drop-in filter
HKS Axleback (not sure if i'm going to keep this or not)

I don't really want to do a full exhaust or HFCs/TPs. I'm just wondering if there is anything i'm missing that I should do before getting tuned. Would getting an HR Y-Pipe and/or a Coupe Midpipe help out power-wise? Other than the things I don't want to do, am I missing any bottlenecks?

 

Looks like that's about it without doing an exhaust or HFC/TP's. An HR Y-pipe would help a little as well. You could also do headers/cams, but if you don't want to do HFC/TP's I'm sure you won't want to do those either

 

loose the cats, i would say its almost mandatory..they'll hold back your tune so much

 

^ +1.

You're willing to buy other mods for the tune, but not the part that will make the most difference? At the very least, get HFC's.

 

I considered them (I even ordered some, but then sold them locally), but ultimately decided I didn't want the rasp of HFCs on a stock exhaust. Nor do I want the volume and drone of an aftermarket exhaust w/ HFCs. I understand I will be missing a little bit of power from this, but i'd rather have a ride I can live with than one that has a few more ponies that I hate to drive.

 

don't bother w/an HR y-pipe since you have an X. look into Fast Intentions resonated HFC's, they're expensive but they're the quietest HFCs you can buy.

 

Why would I not bother with an HR Y-pipe because I have an X?

 

the OEM X y-pipe already has a similar shape

 

I see. That's good to know...thanks!

 

Ah, good catch. I forgot the Y-pipe he has is already basically an HR.

 

Cool!

A coupe midpipe is only for sound, right?

 

Yup

 

Weight loss as well depending on what model you have

 

Thanks...i'm on the lookout for one now!

 

I'd recommend new plugs before you tune as well
