I have these on my 2010 manual z. Along with the Ark Grip True Dual exhaust, Stillen headers, and Stillen G3 intake. I LOVE the sound. But since i put the Ark R Spec test pipes and exhaust on, i threw a service engine code. It was expected though. Now just for a tune. But this is a great product imo!

A tune or a Cel fix would resolve that.

Oh, I'm getting ready for one of those real soon! :stirthepot:

its becasue the dont incorporate a u bend or 90 bend on the 02 sensor bung. for $860 i figured they would have one.....

we're definitely working on improvements down the line, an O2 bung extender as of right now has been working for a lot of people right now

Well the only complaint i had was with the true dual exhaust. It sat on the brace underneath my car but i put some washers to give it some room between the two and its been fine since then!

It didn't for me, I installed them today, reset the ecu and withing 30 miles.....SES again. Waste of 50 bucks...any other solutions? Im getting P0420 and P0430

you need to loosen the bolts on the y-pipe use your floor jack and put some serious pressure on the y to clear from the brace. I did the same thing the 1st time I installed and test drove. Next day i jacked the car up and took the advice from other members...I pushed it so that it touched the top of the car with the jack...when released it sat perfectly in the middle.

UpRev tune.

problem is in cali if i block off the 02 sensors in uprev, the smog check will see that. Thats why I was hoping that the bung extensions would fix it. I plan on getting uprev after I get the motordyne intake

The bung extensions usually fix issues but if it doesnt you can try a L-bung but those usually don't clear our resonator. An UpRev tune would definitely "fix" the problem...
