I just got a Wicked Flow exhaust installed on my '07 tC. Sounds good and all but I noticed that I seem to get slightly worse gas mileage. I should probably do more driving, seeing as it has only been one full tank since I have gotten it installed. I was wondering if that is what I should expect, I thought it would give me better.
However, I have this little area on the way home that I stop at and see how fast I can get my car going. I am not sure how long it is but I start and stop at the exact same place every time. The first time I tried it with the exhaust I got +5MPH faster than usual 100 to 105. Do you think that was just my awesome shifting skills getting even awesomer or is that something the exhaust could have done?


Thanks.

 

its your exhaust...

 

do you have stickers...that could be the trick

 

No, I asked for stickers but they are all out of them. I have Tein stickers, but those just made me drop lower, not go faster. LOL

 

You are getting worse mileage because you are driving your car from 0-100 as fast as you can

The reason for you going faster is a combination of all of the above. The new exhaust will free up the exhaust flow, less gas in the car means that you are hauling around less weight so you will be going faster, and with time your shifting will get better and better.

 

your foot just got heavier

 

^ +1

 

I think it is just me. I only did the 0-100 thing once, but thats funny cause when I went to bed last night I thought to myself "someones probably going to say its because I did that run on the way home." LOL

Thanks

 

duh, wicked flow exhausts add 5 mph

 

Thanks for the input!!!
