well im not sure if its from the tbs or the intake.. but I hear a whistle coming from one of the two depending on how hard i gun it.. I know I've read somewhere on here that someone just has the afe intake and has heard a whistle just from that.

/facepalm

If it was installed at the same time as the filter, this review is kinda useless.

The difference was from the K&N filter probably.

TBS are useless imo and 90% of people just say the sane, my favourite was someone saying "Snake oil, save your money."

Save your money, same goes for their i
ntake manifold gasket.

Prove me wrong, show me numbers with between a 100% stock Si, and a Si that JUST has a TBS (any brand) and I will eat my words.

Check 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.

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 well

Its hard to catch the whistle sound in a video but I was able to find this one on youtube.. its not my car nor is it a civic but you can kind of hear the whistle when the engine is revved.. I hope you can hear it and it gives an idea of how it sounds

I paid 30 something for mine from someone on the forum. I feel/hear a difference without it and I think it looks good in red. If you can get a used one I think it's a good deal. Even if the intake temp is 1 degree cooler or the volume is increased a little it's a good value for 30-50 dollars. Just my 2¢

I have the ingen cai with the p2r tbs, i love the sound the car makes now, but since i installed the tbs and intake at the same time, i cannot tell if the "whistle" is from the intake or tbs, but i believe it's from the intake

Just wondering. Will the 8th gen p2r tbs fit in the 9th gen?

So I installed the spacer, the car feels more responsive, quick.. all of good things, i hear the whistle (once its at 5000 + rpm)...

the bad news, my check engine light turned on... anybody experienced this problem?

And yes, i did plug in the sensor. If the weather is not too cold tomorrow, ill try to take everything apart and install it back on... hopefully the light will go away. Please help.

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!

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.

Yes a tune will increase the performance quite a bit, but you still gain decent power even without a tune. Your A/F ratio might be a little messed up, but over time the ECU irons that out "somewhat."

As for the TB spacer.. I plan to pick one up and a K&N SRI. I do not plan on getting any type of Axle back exhaust unless I can find one with a decent exhaust tip (stock looking).
