Anyways just keep it cool! Occasionally I'll look for unmarked and marked and give it a loud rev! Hell they do it all the time in Oakland and Cops are like "meh" because they got bigger fish to try.

I love having Stealth Mode, Track Mode and two Modes for Noweeds Exhaust Diverters. It makes it so much fun! Love messing with people.

I have an enormous amount of respect for law enforcement but you never know when one will act like a huge douche! I do love having the options for sound, especially once it gets a lot louder being able to tame it a bit is nice!

Question, is there an aftermarket pipe that is bolt on to delete the secondary cats or that's a shop only job?
Tnx!

I believe the answer is no. To my knowledge the only pipes out there are designed to adapt aftermarket exhaust to factory components. And on top of that, they cost more than having a shop cut out and reinstall the secondary cats.

You can use the Borla 60606 along with two Vibrant 2.75" clamps. This does require cutting the exhaust just in front of the muffler. However, no shop required.

So the above setup will just bolt up behind to the primary cats, no cutting? I already have a Borla midpipe and axleback and am looking for a bolt on secondary cat delete. Maybe I can just swap out the mid-pipe sections. Current set up clamps on right before the secondary cats

Correct, no cutting up front. It bolts up in place of the secondary cats at the forward connections.

so looks like part #60626 is just the connector to the cats. Since I already have the x pipe maybe I could just order that.....think I have the 60607 x pipe/midpipes

As long as your current x pipe is 3", I would think that would work, yes. The 60606 is 2.75", though. Not sure about yours.

Some douchenozzle cop got me for illegal exhaust. I'm 110% stock and I was going 30 in a 30. He was posted up at a 4 way stop, half on the right turn lane and half on the sidewalk. I went around him and proceeded right. He follows me across the street to a gas station and pulls me over. He says he's giving me a ticket for illegal aftermarket exhaust work...I never laughed so hard before, he must've thought I came from Arkham. I told him it's stock and he went back and forth between his computer and under the rear of my car with a flashlight, all while telling me I'm wrong. Told him all the specs and he said he's letting me off with a warning. I laughed a bit maniacally this time and said "for what? It's stock, there's nothing I can do!"... sigh. Car sounds too racecar from factory lmao.

I was all about this secondary cat delete until I heard that it amplifies the pops from the exhaust. I'm not planning on getting a tune as of yet but, I would absolutely demand to remove the pops and bangs. So, looks like this is off the list until I can set up a proper exhaust.

Decel pop is like crack. Love it

me too. only thing i miss from my 5.0 with x pipe and roush axleback......very very aggressive setup.

A couple things people seem to miss is... especially with aftermarket catbacks. You absolutely HAVE TO CUT the pipe right before the muffler or flatout cut the cats out.

Stock exhaust = shorty triy headers, primary cats and xpipe WITH axleback. There are only 3 parts to it thus if you take out the secondary cats you don't have a single option but to cut the stock catback at some point. Unless you absolutely get an axle back with xpipe (full catback) combo but not if you wanna keep the stock axleback.

Given you leave stock headers and primary cats alone... In order to replace the secondary cats, you have to either just "surgically" remove them or when you get an xpipe (like me, I have borla catless), you remove the front part that just bolts on to the back of the primary cats and then CUT before the muffles for welding/clamp.

Another thing. SS stock exhaust (also C7s) are 2.75' and you really want to keep the parts you replace that size. LT1 is absolutely perfect with 2.75' exhaust. Going 2.5 or 3 actually hurts and doesn't benefit anything (feel free to look for Borla's research on this as well as talk to Chevy engineers if you see them at an event) where as LT4 (ZL1 and Zo6 AND Ctsv) has 3's all around because that's what the engine works best with.

Also, when replacing secondary cats... Especially on manual, as long as you don't have any leaks due to install (make sure the welder uses an arcing welder and not straight one because he won't be able to weld the top of the pipe thus causing a leak and that leads to CEL) you won't have any issues. I've had mine installed almost a year ago now and zero CELs. As for the A8, you may have to reset the AFM parameters by disconnecting the battery and all. Not sure how it works as I have an m6 but feel free to contact the exhaust manufacturer and they will guide you on how to.

What do you mean "reset the AFM parameters"? I've not heard this before.
