i want to change the header on my z,but i do not have any idea between which one is better.please any help or comment will be appreciate.thanks

 

Aren't they the same headers?? To be honest, i cant tell the difference between
top speed headers and strup headers. THey look identical.

 

I'm selling my Alphawerks in Jet Hot 2k coating to go boost. The performance from these headers inspired me...no low end loss...but from 3K...redline comes REALLY QUICK.

let me know...only installed for 2 weeks now...pretty much new.

 

thanks a lot,but it is imposible to buy to you, because i live in chile (south america) so i need to pay with credit card,so is dificult to me it is more easer buy to a store. although thanks

 

search the intake/exhaust forum for "strup" then do another search for "topspeed" and you will get all the info you could ever hope for.

 

I have the Top Speed headers and did not notice a real difference when I installed them. Crawford is running a GB on their headers fro $900ish. Thats the way to go!
