Thanks!

Been looking at Arith's build for some time, it's got some inspiration to it! I also love that you help out so much with all these replies, it's definitely given me a lot of second thoughts about some "cool sounding mods" I've looked at.

I was hoping for a video with both stock and the X Force in it, although I've searched the internet and couldn't find it myself, and those are great videos themselves. I've heard that the closed valve on the X Force sounds close or a little louder than the stock muffler, if anyone can confirm that? I can kind of get a preview from the Panda video with that information.

Lol, feels like I have to type so formally on forums compared to what I usually type like

 

Forgot to add this in the original post, but does 91/93 octane really make a difference on a bone stock GT? I can kinda see why, being turbocharged and all, but is it really that significant? Saw something about a Soul dropping a 1/2 second on a 0-60 with 93 and it blew my mind. If so, what should I run? 89/91/93?

 

This is one of THOSE questions that will illicit passionate personal responses. No one has done any thorough research to prove 93 is really worth it. I too have seen the article about the Soul.

I run 87 in my GT because I don't drive it hard. However, If I was intending to use it for maximum power I would run 93 all the time.

 

Regarding octane, always refer to your owners manual.

I run top tier 87 octane in my GT. My GT managed to dyno more than the advertised/rated HP/TQ on 87 octane.

Got this off the EVilla Motorsports websites, which I highly recommend to buy from. Hope it helps.

 

That helps alot, thank you!

The only real reason I‘m buying from X Force is for the valves. Comes in handy around cops. (and partly because a 3“ pipe sounds cool)

 

I have the Evilla cat-back exhaust with Magnaflow resonator (midpipe) and Evilla sport resonator (muffler position) - it is not loud unless you open the throttle....

It is loud when you open the throttle, but normal driving it is not going to draw the cops...

 

Also, I notice how everyone keeps talking about the Boomba shifter kit. My shifter is definitely a little floppy, and feels like the car has a dying wish to get out of first gear while having trouble getting into second. I'm wondering if I would need the entire kit for the entire experience, or just the transmission adapter? I'm definitely wishing to get a new shift knob though, but it's not at the top of my list.

I just installed the shifter/bushings/knob yesterday. I have the transmission adapter/bushings too but I won't get them installed until next weekend.

First impression of the shifter upgrade-- DO IT. The slop is gone. Just gone. I can't express with words how much better it is.

As far as knobs go, since the stock shifter is some lame proprietary contraption, you have to replace the shifter to use a different knob. If you only get one mod, do the shifter. It's a little time consuming and involved, but so worth it.

 

Ordered the catback yesterday. Shipping says 1-2 days, but man oh man I can only wish it takes that long.. ended up going without the valved portion. Can always add it on later.

I‘ll see what I can get for scrapping the stock exhaust, if I pull enough out of it I‘m between the Air Design front splitter (it just makes the front end look SO good) and the shifter. Probably nothing else will happen for a fat while though, so alot of time to think.
