I removed the factory midpipe from my tC over the weekend to test at the local drag strip.

I am running a factory intake, s-pipe and header.

First off i must say that deep rumble sound was more than I expected. There was no rasp at all, just a deep loudass rumble. People at the track were comming up to me asking what I had in it.

Interesting that the 1st cat in the factory manifold created enough backpressure for me to actually improve my times by more than a quarter second.

In the eighth mile, on a hot saturday night. I ran a flat 10 second time. A whole .3 less that the last time I was there running a K and N (which I no longer have).

Total time to remove/install the pipe was 15 minutes. Overall, it was just a fun test for me and I enjoyed the temporary deep rumble that the stock tC provided.

 

You should hear MY car with an unbolted muffler! Tons of rasp but it sounds freakin Formula 1!!!

 

you should hear it with a header installed!

 

oh man, you were out at the lakeland drags? must have missed you.

 

I have a header! I love driving in tunnels

 

How about the echo when you pass a car going to other way...

 

What Midpipe are you using? The only ones available on ebay are Megan.

 

I think he means he removed the s-pipe altogether and went with a straight header/manifold

 

i would love to hear an open header set up on a tC. Im too lazy to try though
