Hello i had a few questions I would like to ask. I currently have a 00' w/ megan racing header, and test pipe, hks hipower exhaust. I was thinking about changing exhaust to invidia single 70mm. Would I be gaining? due to my test pipe being smaller than 70mm? Or should I just stick with a 63mm exhaust? Im trying to get an invidia i miss having one of those. :]

any thoughts? on which I should go with?

i'll be running 1/4 mile and dyno in 2 weeks ;] :]

Thanks

You would likely gain with the 70mm even with the 63mm TP. Do you have the Megan TP?

 

yep megan racing tp

 

anyone have any experiences with 63mm test pipe and 70mm exhaust? any dynoes?
