Hello!

So I've finally got most to all of the repairs and quick fixes on my GS4, and am looking toward some performance parts.

I've got a budget of about $500, give or take a hundred, and am able to do all my own work. I've been thinking about 4 different mods, but unsure of where I should start, let alone brands etc.

Here's what I'm thinking:

1. A nice head unit (navigation, stereo, etc.)
2. Intake and Tune
3. Exhaust
4. Headers

I don't have a lot of experience in these things yet, but I know that I'd like to keep the original feel of the "luxury sedan", and to keep things somewhat quiet or toned down. As far as performance goes, anything that I can see/hear/feel a noticeable difference. Your suggestions are greatly appreciated!!

First thing I did on my gs4 was an intake....(cant really do a tune) was a good upgrade for the money.

 

I believe he is speaking in regard to the SRT intake and piggyback AAFC. And you can absolutely tune with an Apexi unit.

More relevant, I'd go with a cool head unit (Pioneer AVIC is my favorite), or the SRT intake/tune. I really love mine. Great noise! Definitely tides you over till you get exhaust.

 

I would definitely do the srt intake! I just installed mine today and man let me tell you it sure makes my car alot more fun to drive! I also have a L-tuned exhaust and it sounds great together not loud but def not quiet!

 

I wud go with an intake as well as ur first mod. I put on a K&N. But the problem wit K&N Is that it becomes sluggish in low RPMs but it does kick in at high RPMs. Nice tone too!!
