Does someone have a link to the OE Flash Tuner? Do they offer customer files for 91 / 93 or 100 octane, that you can switch from? Thanks, Dave

I talked with Andy today about the headers and how loud they are. Has anyone added resonators to their exhaust to try to quieten it down any? How much louder is the car from the inside during normal driving? He suggested an X-pipe to help quieten the exhaust some but I didnt know how much this would help if any? I personally think any x-pipe makes a car sound raspy and more high-pitched. I have always been an H-pipe fan when it comes to sound I know an xpipe may make another few HP but not a big difference. Doesn anyone have an H-pipe on their car?

Does anyone have cats added to their MHP exhaust? If so did it quieten it down any? I dont really car about the smell from going catless.

I had MHP headers with no cats on my old c 63. I can tell you that cold starts and WOT are brutally loud. A cold start in a parking garage was like dropping a M80 with a serious echo. Normal driving is OK, but crack the throttle above 2K RPM and it's obvious.

If you're worried about the sound level, you need to get the x pipe to replace the secondary cats. I would get it anyway as it will add some hp and smooth out the exhaust note, just a bit.

The stock resonators are basically an H pipe so you already have that.
