recently took off my exhaust to run straight header.i am running an nx express kit will my car still have a major loss of torque even on the juice?

 

put the exhaust back on, even with the juice.

 

i dropped 3 teths from my times open header
what motor are u runnin ? and no matter how much nos u have u will see big torque gains , with nitrous u see more trq the hp dyno provin , run it yes it will make a diff oh yah so when do we race at an idle

 

SOHC VTEC, Stillen 4-1 header.

Open header and NA I lost .3 tenths.......

Open dump tube and 75 shot I lost .2 tenths.......

I prefer the straight pipe.........

 

i have a d16z6 with several mods,on slicks 22x8x14 i run 8.50's in the 1/8th pretty much every pass,i thought it would open it up some but was not sure,thanx for the input anymore would be greatly appreciated.

 

so to what point in n/a does an open exhaust start to help?


i'm turbo, but, i'm curious

 

when you have a long enough tuned collector.

I'll let Dave @ SMSP or John @ HyTech cover the "old school" collector tuning.
