The SP Quick Spool valve and our SP Boost Acticated cutouts have been becoming VERY popular and are proving to be well worth the investment. We are now looking for Distributors as well as Retailers  who are interested in carrying our valves and cutouts.

If interested please inquire with us.

Our boost activated exhaust cutout allows you to just drive and not worry about flipping switches, etc.. It uses an actuator to open the valve on its own (fully open at 11psi) so on full throttle it opens the second it hits desired boost. You can run it off of the actual actuator (11psi) or you can keep it closed by wiring up a solenoid to tell it at what boost level to open.

It’s full stainless steel construction is virtually indestructable and will not bend/break from usage. There are no electric motors to fail, and it opens extremely fast vs the alternative products on the market.

Available in 2.5″, 3″, and 4″ Sizes.

First of all thatnks to all who came out even though the weather didn’t cooperate, It was cool to hang out with you all!!!

It was cool to see the Nissan guys come out in a group of 20 or so!!! those are some sick cars!

We didn’t have as many supras and Muscle cars as I expected, but I understand… the weather man wasn’t very promising with his outlook for Saturday. It turned out to be pretty good.

We had a wide range of dyno #’s form the high 100’s to 700 HP!!!

I ordered 35 Pizza’s and I am pretty sure they were gone in about 10 min…. But with 200 people in attendance, I didn’t think they would last long. Thanks to the Chi racing culture guys for hooking us up with Chicken and grape Juice (It was suppose to be GRAPE DRINK!!!) but either way it was good!!!

I do plan on having a few more events here at the shop through out the summer, so keep checking the site for info!!!

Well guys the SP open house is FAST aproching!!! It is Saturday April 25th!!!!!

I have been getting tons of responses from car clubs that will be bringing cars down to the event. I have supras, 350 Z’s, A r32,33,34,and the new r35 Nissan Skylines. The Domestic Crowd is coming out as well with Some of the Fastest cars in chicago!!! Better yet the weather looks to be perfect on Saturday!
I called our friends over a O’hare Towing and recovery to come down with one of their new trucks and Possibly a film crew for their TV show on Speed call wrecked. So make sure you come on down and hang out with us at SOUND PERFORMANCE!!!!
