Meth kit and Downpipe recommendations??

I have a 2009 and have recently purchased a Cobb tuner, ETS FMIC 5", ETS intake, ETS Chargepipe and Synapse Diverter Valve.

My next purchase is a downpipe and/or meth kit. So far I have read that with the meth kit, I will need to take it to a tuner to have it professionally tuned. I was going to ask what people would recommend. I have heard some systems have failsafes and others don't. Obviously the one with failsafes is better, but again, I was going to ask for some experience and advice to what I am looking for. Any advice will be greatly appreciated.

As far as DP's I have read that AR fits the best and such, but it really comes down to brand preference. Is that true? I would like to save a few bucks, but not risk quality. Any recommendations?

I was also curious about gauge clusters for Air/Fuel ratio and Boost gauge. I don't want something to look ugly, but I do want to monitor. I have heated seats and don't want to lose that so cluster there is out of the question. I would like to know if there is a gauge cluster that goes on the part of the car that runs from the dash to the roof of the car on that beam. Does that exist?

Thank you for any advice/recommendations.

With regard to gauges, check out the P3 vent gauge.

As far as meth kits go, the only kit I recommend is Aquamist. Whether it be HFS3 or HFS4.

DPs are pretty much brand preference, although AR, AA, CP-e and (lately)VRSF are definitely the major players.

There are gauge pods that mount on the A piller, mount on the steering wheel column or the P3 gauge that goes in the A/C vent.

get the Aquamist HFS4, it is a great kit (go for trunk mount). tuning shouldn't be a big problem. you can do it yourself with ATR and use the race map (race fuel) as a starter.

as for gauges, I don't know but I use my COBB AP as my gauge. just mount it using a smartphone holder. keep the cable routed

I was looking into them, and I love that they're well hidden, but I was hoping to be able to monitor both at the same time. Kind of. I mean, in all actuality, do I need to monitor both at the same time? Which would be better to monitor A/F or Boost? opinion question of course. Just looking for some insight.

I've been told Aquamist as well, just sucks they're so freaking expensive, but I know you pay for quality. I have a Cobb Tuner, but it sounds like that was a waste of a purchase if I do go meth so I'm starting to think it's better to not get that just yet. I only have a grand to play with and I haven't got DP's yet. So I really can't afford that specific meth kit. That is why I'm thinking DP's with gauges.

I was reading forums and I think the route I'm going to go is the vent mounts for both the center left and right. I can monitor A/F and Boost, but I can't find matching gauges that will fit the holes.

FBO + E85 => race map shortest and cheapest route for more power
