better mod
 

which mod is better bang for your buck a tuned pipe, heat sink head or a motor saver air filter.
keep in mind this is not best mod over all, but best bang for the buck

RE: better mod
 

well generally a mod is for increased performance so i would definately say the tuned pipe. the right one that is. some can damage performance if your not carefull.

RE: better mod
 

yeah tuned pipe is best by far. can increase revs by an extra 1000

RE: better mod
 

yea, i think the tuned pipe would be the best, but on some thing like an rs4 2 with the 15 fe motor might benifit more from a heat sink head, to lower tempuatures and there for be able to run the motor more lean
