Exhaust. Do you have the NPP? If not, Bullets give the most power as they have no mufflers, just resonators. Borla ATAK copies them, but for lots more $$. Some don't like the "drone," I don't even notice it. Sounds like power...if you have the NPP you may not want to spend the money for the improvement. Headers help no matter which way you go. BTW, love my 105S Halltech. Perfect match for the Bullets.

Don't forget "TIRES" and you have 19" rear wheels, and you should try to use at least 18" size wheels..
Your going to HAVE to get a set of DR's... I use MT and my best 60' is 1.59.. & I ran 11.59 (best)
I just got a 403" ci stroker motor and plan on taking it to the track March 7th to get it tuned & set the shift points...
I expect to run mid to high 10's....

A tune will net you the most out of any stage of your modding tree you are at. We offer remote/email tuning VIA HP Tuners. The best part about it is, we can work remotely with you on the street, at the track, or on the dyno to get every bit out of our setup that it is capable of. Within minutes.

I was getting a very slight surge with the stock intake and the shroud propped open at 60-65 in 6th. Plus, a noticeable smell like hydrogen sulfate/sulfide when I got on it--running very rich. I have a '13 coupe and am at 7000'. After the 105S, no surge and the smell became just a faint whiff. I opened up the shroud, after conversing with Jim, at the driver side corner a bit, and the car seemed even more responsive with at least double the outside air getting into the air box now. You can't open it under the filter, his MAF forward design is very touchy about turbulent air, but it is already open on the passenger side where wires run through, so I matched it on the other side. Air flows to the sides of the K&N filter he uses, so no turbulence and no surge. And that air comes in from the grill, so is ambient temperature. Probably doesn't add much, but cooler air is always a good thing. Biggest improvement was running far less rich and I didn't lose any power compared to the propped open shroud. Just the negatives: surge and way too rich were eliminated. After opening the other side, the slight whiff of HS was almost completely gone, so I'm guessing the modification is making it run even leaner, which is what I want at this altitude. Very good system, well engineered, and well supported by Jim.
