Want to see how people like the tbs. any vids of how it sounds, or if they notice a difference.
Oh ok, I'll check that out, was kinda paying attention to pictures rather then links. If first car is stock then its definetely doing something right. I need to find a dyno and I'll test this myself as wellCheck out the link. Right at the top one of the very first things he says is that his car is stock on the first run and then stock plus spacer for the second.
The other link, the guy with the 1.8L has a number of mods, but he does a before spacer run and then 3 runs after spacer to show the dif.
All I have is a Full Race Catless DP and Resonator Delete with stock everything else and I definitely know my car is quite a bit faster. How? My nephew also has a 9th Si. I pull on him every time. And I used to lose to my friend's FRS. He loses to me now.. until he starts modding his lol.Just a heads up before anyone just jumps in and starts buying things..........You WILL NOT gain 10-15hp from an intake, downpipe or exhaust; not even from all of them WITHOUT A TUNE. If you want to add 45hp plan on spending 5K plus on all these parts and a tune plus forced induction. Also be aware that if you do want to add massive power to this car the 17" front wheel drive may not let you utilize all the power you plan on paying for. I love mod's too but be aware most of them should be for your own preference and sound. But this is just my take on it, more power to anyone who figures out how to gain 45hp from less than a 2k investment; please show me proof and I will do the same!
