catless...
EDIT: i don't have any intention to make my car sound like a v8 so please stop with the "you should have get a v8". thank you
Hi everyone.. i have a 2014 Lt camaro.. before deciding to get a blackheart hooker downpipes this is what my car sounds. SETUP is: KN CAI,SLP LOUDMOUTH1, XPIPE(REGULAR NOT THE RESONATED) and a trifecta tune. After adding the downpipes my car sounds shit now (not just rasp and drone,i know it would happen) and it won't go above 2.5k RPM like it used to, i mean i can slam the accelerator and it would go 3krpm but it would take such time. http://imgur.com/ob4X62j http://imgur.com/H5VkBF0 http://imgur.com/vU1HAYV i dont know if this is a gap or what. here is the picture for reference i really need your expert advice. please help me. thank you very much! -- neekoorgc - noob car guy |

Those clearly are the wrong parts, you shouldn't even be running it with the gap on the head flange like that, you could burn a valve. Send the parts back. If that side fits that bad I imagine all the exhaust ports on the head are misaligned so that is probably why it won't wind up. I've never worked on a v6 but maybe they are for the earlier version of the engine. I've read that one of the versions you can't put headers on it... Not sure which one tho

I have a 2015 LT with factory downpipes, and I have that gap on both sides of that flange as well. That's probably not it.
What is the deal with your O2 sensors? Did you replace them or put your old ones back in? Are you sure you put the upstreams in and not the downstreams? |

The O2 sensors tell the computer if the engine is running rich or lean. The upstream ones are different than the downstream ones, so you can't mix them up. A muffler shop knows that though, so that's probably not the case, but it is a possibility if the dude wasn't paying attention. Is your car tuned or running the factory tune?

If you're going to the muffler shop tomorrow, just have them confirm that the O2 sensors were re-installed correctly. Beyond that, I think your solution is going to be a retune with Trifecta. Incidentally, does the car run any better when it is completely cold? |

There is no way that is sealing the head to the flange. Stevie Wonder's Muffler Shop?

holley performance just replied to my email. and they said that the downpipes should be pair to their full exhaust setup. i think its BS because i know some people who runs catless downpipes but different exhaust setup. ive just emailed them that i will return the product. goodluck to me.

Again, your problem has nothing to do with the pipes. Its going to be an issue with the O2 sensors or the tune. Most likely the tune because now that you are catless, Trifecta needs to turn off the rear sensor.
