No they do not respond well to bolt-ons. They respond alright to a tune, but bolt-ons don't do much at all for them. A full header-back exhaust nets them around 10whp. There is no way that 08 SI is anywhere near 230 WHP. Not even close. He's lucky to be close to 190-200 whp. I've seen comptech SI's push 230-250 WHP with 4-5 psi.
I used to own an 08 SI.

Give me a break man. I actually owned one and know for a damn fact its hard to squeeze 200 whp out of them with bolt ons. This 220-250 whp with bolt ons is pure nonsense.

"2006 Civic Si with Intake/Exhaust/Raceheader/Hondata Intake Mani Gasket NO HONDATA REFLASH!!!"
That was with DR's. Throw some slicks on and it's lower 13's.

Here's what I found from an article testing each bolt-on in the SI.
Conclusion
Testing to our '08 Civic Si reinforced the inescapable truth that increasing power in newer cars is becoming increasingly more difficult with simple bolt-on parts. The mechanical advantages of all the parts we installed were visually apparent, yet the power gains weren't as large as some we've seen on engines with far less potential than the K20. while every part we added made power, seeing the Ecu adjust to compensate for each change all but proved to us that more power could be made. Does this mean you shouldn't waste time modifying the newer platforms? No, it simply means there's more to be discovered through tuning. Look for a future installment of Power Pages, in which we'll be testing an engine management product that claims to offer as much power in one step as we've made here in three-proving the new Si isn't a platform to be overlooked.
CONCLUSION..12.3 whp gain with full bolt-ons, no tune.
BASELINE...172.1
FINAL ........184.4

So at 14.4 being one of the quicker stock ETs, that guy is claiming to knock .9 off with bolt ons, DR, and stock tune. Something is way off there. If it was done on a 1.8 I might buy it, but not on a 2.0. I just don't know about you anymore, Jeff
