i am currently running tvs and i have the vibrant 4-2-1 header and down pipe
is it worth spending over 700 on the long tube or should i just stay with the vibrant

 

Don't know about the OTTP longtube but one thing I don't like about the Vibrant is the placement of the front O2 sensor. It is only reading from two cylinders as it is located where two of the primaries come together. Would much rather have it generating some mv's from all four cylinders. Other than that they are great headers.

 

I'd stick with the vibrant. I like the OTTP better but realistically there would only be marginal gains

 

^^^^ agreed

BUT if you want real power on a TVS among other things you need 3 inch exhaust and vibrant is 2.5. And u need a ported head and this assumes you have very good cooling mods....
