Are there any differences between an STi Up-Pipe and an aftermarket one in regards to diameter/flow/gains/ect.??? If there is no reasonable difference, does anyone have one they'd like to get rid of???
An aftermarket one might have a bigger diameter and flow more. The downside is that it'll take longer to spool. Unless you've got engine work done and you're got that much more exhaust gas exiting
Really?? If so, thats badass. I havent taken the time to look, i figured my 06 would be nearly identical to my old bugeye...
Yeah, i knew about the injectors. I had no idea about the up-pipe though. Some other wierd stuff was the plastic TMIC endtanks and the air-injection system.
Yeah, check it out, you have aluminum bits down below as well! But like I said when we were talking, the plastic endtank thing is really disapointing. But otherwise we got lots of nice bits as upgrades. 06's are completely different beasts compared to the previous WRX's.
Sweet!! I just went and looked at the uppipe with a flashlight! Im gonna take a look underneath it sometime soon as well!
