I have had a lot of people asking me questions on the SMSP set up I have and I decided that I should do a write up with all the information I collected so here goes…
SMSP header

SMSP highflow cat


SMSP intermediary (magnaflow resonator)


SMSP muffler (magnaflow resonator)

All together

Now for power. I took my full stock ITR to the dyno and got these numbers:

Dyno graph:

I bolted up the whole line (header, cat, exhaust, along with a comptech icebox and a K&N filter) and headed back to the dyno. Here are the numbers:

Now for the comparison of both curves stock (RED) vs. modded (BLUE)


Torque comparison:

Along with this here’s a run I did on the track with non drag slicks and horrible conditions (95 degrees and very humid)…
13.7s run

All in all I’m more than happy with this set up. I can't imagine anything better. This is with NO tuning , just bolted on. I have yet to tune the motor and see what numbers I will be pulling. Also the peak value I got is not what it should be the dyno guy let off the gas too early but what matters most is how we can see a 5-15hp gain throughout the whole line! I hope this sums it up for everyone.
There has been a lot of questions on the sound. Honestly for a 2.5" exhaust it is basey as you heard in the dyno run. I love the sound. It's not at all highpitched. It almost doesn't sound like a honda when you hear it driving on the road. I was also concerned with how much sound it would be making and it's not at all a problem what so ever.

I got it used off of Keith in Florida. ITR004. If I remember correctly the whole thing cost me 1700. Including the intake.

Would you know the part number for this muffler (resonator)? I really like it and would like to add it to my custom exhaust.

If I'm not mistaken, it appears to be Magnaflow P/N 12636:

I think you're mixing me up with DCR2girl, she's from switzerland. I'm planning on going for the JDM front. I want to go HID and I love the front. I hoping I'll have enough money by this summer to go for it.
For the motor I'm hesitating between vtec controller and uberdata. For the moment I don't need more than that. When I install cams and rebuild the block (higher compression, etc) I'll probably go for AEM EMS. I can't wait but it's great to watch the car evolve equaly in both areas (suspension and motor).
Thanks for the feedback!

Sorry, no I don't know the part number. I'm sure Dave from SMSP will help you out.
Talking about Dave. Even though I bought these parts used he was more than helpful. We threw back and fourth 20 emails talking about the curve I drew. He also was a great help when I called for questions. He's great to deal with!

Do you know what kind of dyno you where on?
And you really need to lower you vtec. Loads of midrange power to be found

Judging from your last video your top speed on the dyno was 225kmh -> suggesting you used 5th gear on the dyno... That would read a bit lower than using 4th gear.
Those Bosh dynos read very low numbers. Perhaps too low. I also dynoed my stock ITR on a Bosh dyno a while ago, and got 142whp (which is about the same as you got in the first video). After bolting on I/H/E/Remove PS, I dynoed on a US Mustang dyno and got 182whp, which in turn would be about the same as 200 US Dynojet whp
. Just FYI.......
