there's nth wrong with my headers, i love the gain in high rpm

but i found out my car's low end torque got sucked up a little bit than b4, is that normal??

i heard they said now the power in high end so there will be less torque in low rpm, i started to kinda feel it too, is that true to the TL?

anyone notcied the difference?

 

It's been discussed before that this is a side effect of headers. CompTech's dyno graph shows a 0.4 lb ft drop and a 0.4 hp drop at 4,750 rpm, although I'd be surprised if something this small can be noticed.

 

i noticed that too.. but its not that bad.

nothing pulley's wouldnt fix!!! the pully has a nice gain all around the whole powerband. you should definitly try finding a nice underdrive pulley to fix this loss problem

 

yeah but not now, i am trying to do the BBK now first
