Has anyone tried to disconnect the y-pipe at the connection to the Cat for the 1/4? I am sure it is loud but would be interested in hearing results with it disconnected vs connected 1/4 mile times. No backpressure will probably make it slower but I would like to know.

Hehe! You actually lose a LOT of power. I have tried it...well not on purpose, I had a muffler shop loosen those nuts for me and had it just blowing a little bit. The power loss is incredible! Why not just take off the whole Y pipe? Hehe!

Your 1/4 mile goes to about 10 minutes!

 

I ran a 14.6 with no Y pipe and no exhaust. The low end did suffer, but I did blow the factory clutch on that 14.6 run as well.

 

Wow. How loud was that thing?

Loud as *****. The drag strip I go to is like hickville. Theres mostly american muscle cars there, and most of them are pieces of crap that go fast. All the hillbillies were like "wtf is that thing?"

 

hehe kinda funny. So now gains except for the attention of hillbillies huh? They give you less HP than some maxima.org stickers.
