Well i have a test pipe lieing around from when i had stock exhaust...I have simulators's in the car so i can put it on at anytime without throwing codes...I don't use it anymore because with the apex n1 its sooooo loud...but i was thinking about maybe putting it on for just autocross...how much diff. do you think it would make?
I have no other mods btw that affect power...

 

any opinions please?

 

it will give you much more bark then bite - but it is lighter, and you might get a couple HP depending on the condition of your cat

 

IIRC if you're doing Solo II you're suppose to still have the cat in... again IIRC. I thought I read this somewhere (which I haven't really cared about because mine's sorta still there).

 

well..screw the stupid test pipe i guess...it'll wait for turbo
