That's a pretty big difference imo. If I was to go catted, I would probably go with cobb.

Thinking Cobb as well. Would love to hear feedback for others but doesn't appear to be many catted options.

I have upgraded CP, FMIC and BQ Tune so looking forward to this mod come Spring. Also have to pass emissions every other year. Running INA0S so hopefully monitoring plays nice with DPs.

Definitely get in touch with him BTW. If you're going to change DPs, might want to wait until after, but he can whip up a map and tweak later if needed

I have the Cobb catted, which replaced AR catless. The real smell (and smoke!) problem with the catless came when I swapped out the secondary cats for Vibrant 1790 resonators in a fruitless attempt to get rid of the rasp. Before losing the secondary cats, though, I didn't really notice much of a smell problem -- and I back into my garage.

BQ convinced me to switch over to catted -- to his mind, the loss in HP is relatively minimal and was worth it to avoid sounding like a ricer all of the time when you wind out the lower gears. However, he had the CPE catted. I don't know if they are better/different than the Cobb, but I will say I haven't totally lost the rasp with the Cobb. It's better overall, and on occasion even non-existent, although sometimes it doesn't seem as though it's made much of a difference at all. YMMV. My IS is an MT, and an E93 to boot. If I had to make to the decision to loss the AR catless and put in the Cobb catted all over again, it'd be a tough decision, but I'd probably still do it.

Anybody here running inlets on their IS? Which ones and how do you like them?

[gregsatt]

Well, I've worn out my rear tires and want a little more traction.

Am going with PSSs but am still undecided on the size. The 265's are $92 less each than the 275's. Is there much extra traction on acceleration with the 275 vs. the 265 to be worth an extra $200?

I understand that I may get a little but of rub with the 275s when under load, but it is rare that there is more than a hundred pound kid in the back of my car...

Any advice is welcomed.

Thanks,
Greg

That's not very reassuring. Sigh. I'll probably go with the catted though. I guess it's the price we pay for power.

Just wanted to join the group. I picked up my 2012 iS in Atlanta, just under a year ago, after moving to NC from Kauai. Paid 32K with 28,000 miles on it. Absolutely love the car. I came out of the theater the other night to a dented hood. I'm thinking about replacing it with a CF hood and getting it painted AW. Anyone installed a CF hood on their iS?

I don't know if you're running a spacer but 275's on stock 313's are fine. I have Yokohama Advan Neova's and the traction is outstanding.

Howzit brah. No CF here but nice ride. Kauai to NC?

In case some of you were wondering what a straight pipe into the 335is mufflers sounds like here you go. It's very raspy and most won't like it but when you go WOT it sounds great and mean. On the DCT you have to keep revs above 2k or else the drone is insane and no one not even me can deal with it, but I drive in manual mode all the time anyways so it doesn't affect me

[JunkyardDogg]

^^ whats the difference between a straight pipe and a catless dp?

Not a true straight as in I still have the rear mufflers on but the I have Catless downpipes and the secondary cats are also removed

Have you tried going Catless DP only with the stock secondary cats still on?

I wonder if this will remove the rasp problem, otherwise it sounds pretty good.

That's what I originally had and wanted something louder for the hell of it for a while. With the secondary cats in its fine, all I got to do is weld them back in whenever I feel like it

[JunkyardDogg]

I'm about to pull the trigger on the MHD. Wanna test it out on stock 93 oct and ill add in mods later.

This is what i've gathered so far:

DCAN

OTG
http://www.amazon.com/gp/product/B00...A1AMUYYA3CT6HJ

Android tablet

And of course the tune. Am I missing anything? Battery charger?

Hey guys. New IS owner. Picked up my E93 this weekend, and I'm quite happy with the car so far. I got DPs and an intake in the mail. I've done my fair research on tuning the car, but I wanted to hear it straight from the horse's mouth with our IS models.

• Any advice on using MHD and/or the Wedge maps that can be purchased?
• Should I be looking at Stage 2 or Stage 1 maps with just an intake, DP, and 93 octane? Stage2 states FMIC required?
• What options do I have outside of Wedge for optimal power output without purchasing a FMIC yet? or am I wasting money on downpipes w/o an FMIC? Custom tune?
• I'd like to have a fairly consistent and reliable tune to put the car close to the 400/400 mark. Research points to this being relatively easy. Thoughts?

[mwa12E93]

I have a '12 335IS E93 w/ 19" 313 wheels. While I recognize that 30 series tires running at near 50 psi are going to ride a bit rough, when I hit a manhole cover the other day that was about 1" below the street surface it felt like the wheel was being torn off the car and it crashed hard like I hit a curb at 40 mph. Is this normal for this car? I'm trying to figure out if work needs to be done or if I just have to be hyper-vigilant about potholes and manhole covers.

Thx

A custom tune by BQ would be $ well spent with the DCT. You can go as mild to wild as you want. I don't know if the different stage maps are separate purchases because I use custom tunes, but if they aren't you can experiment with different ones, logging as you go, to determine which works the best.

DPs are a given here in FL, especially with no emissions inspections, so not a waste of money but you'll definitely need to upgrade the IC. Once our little cold snaps are over you'll be heatsoaked after one good pull and things go downhill rapidly from there.

[gregsatt]

I noticed that the inside of my left rear tire is really worn. Chunked off down to the threads. The right is written pretty evenly. Is this normal or is there an alignment issue? About to put new tires on and don't want to ruin them.

Is there anything special about the rear alignment I need to pay attention to? Our should I just go with factory spec?

Sears is silly enough to warrant the pss for the full 30,000 miles even with the staggered set up, so I'm going there for tires. Should I worry about them being able to do a good rear alignment?

sounds like the toe is off, happened to mine after I lowered it.
Get an alignment and you'll be fine. As far as getting one from sears if your looking to retain factory specs you shouldn't have an issue, although I can't comment from my own experience with sears

I'm not sure exactly what tires your running but 50psi is pretty high. you should refer to your owners manual to what psi you should be running and not be filling it to the max.
Another big issue is if you are running runflats, they tend to ride more harsh because the side walls are very stiff.
Also its very smart to start avoiding potholes and other road obstructions to avoid alignment problems cracked rims etc.
