Hi everyone,
I'm only just thinking about this at the moment tell if this mod is worth it? what does hi flow mean?
I plan on getting an exhaust system for my R33 GTST it is a 3'' cat-back from the turbo with 2 4'' mufflers on either side of the car. Hi tech mufflers have quoted me $1000 for the job. do you think this is worth it? will i get a slight increase in power/ performance?
Thanks for all Da help
