I would get rid of the stock exhaust manifold, it's heavy and more like cast iron with rough edges inside and out. I deleted the resonator and the cats and went with straight pipes (off road). I used the stock H pipe in the middle so I can get that old school choppy sound. You can go with X pipes in the middle but it will change the sound to more like Euro hot rod. I used the stock muffler, it's well made and has the flap control with fuse in or out. With fuse in it will open under 2000 rpm, over 2000 rpm it will close. With fuse out it will stay open all the time (more sound). See picture: In black, I got rid of those. In red, that the lift points. In green that the jack points. Yellow is the stock H pipes or change it to X pipes there. Good luck and have fun with your Z. |

Sound of my Z/28. This is just headers doing its work. Everything else is stock. Turn up the volume loud!

Have ARH long tubes stock cat back and H Pipe with mild to wild switch. Exhaust Flaps are always open. Car is cammed. It sounds pretty sick. Gets a lot of attention from the sound alone.

Post a video, would love to hear it. I'm thinking about doing a cam later. What kind of cam did you use? ARH is well made. Pricey as well. Last edited by pzero; 04-02-2020 at 11:15 AM. |

Short system uses the factory mid pipe Long system uses the ARH mid pipe. Both short and long systems use the same longtube headers https://americanracingheaders.com/co...5-short-system https://americanracingheaders.com/co...15-long-system |

I have had a couple different set ups on mine, started with the ARH short long tube kit without cats running through stock exhaust...really liked the sound but wanted to try the larger mid pipes so I tried the ARH long kit with the X pipe that also replaced half of the tail pipes to stock mufflers. I really didn't like the modern sound of the X pipe and wanted to get it back to more of the old school muscle car sound but found out that nobody makes a 3" center section with an H pipe built into it. So it was either put the stock 2 3/4" H pipe back in or build a custom 3", I wanted to get away from the stock front section right at bends to where they come together because the factory pipes in the section do have a few bends or crushed flattened areas for clearance in this area. Last fall I built a custom 3" center section with a 3" H pipe, only got to drive it a couple times but so fare very please with the outcome and with the sound.
I have been temped to try different mufflers at times just to see but its very hard for me to get away from the flexibility of the NPP mufflers. I will also say that without cats and the mufflers open this set up is very laud, so much so that I ended up putting a switch into the NPP control that I can open and close the flaps when I want, most of the time when I have it on the street they are closed. The thing still has a good sound when they are closed but not near as obnoxious. Just my experience, most people like the x pipes sound now days but me I must be different or old LOL but give me the H pipe sound anyday. Hope this helps some |

Buy the 1 7/8" long tube system with X pipe from American Racing Headers. Leave the stock mufflers in place and pull the exhaust flap fuse in the trunk. Your call on cats or no cats as related to vehicle inspection vs. performance. Consider getting a ceramic coating on the headers for better heat management. Get some ACCEL Extreme 9000 Ceramic Spark Plug Boots part 9070C, dont cheap out with heat socks and try too keep the stock boots, just get the ACCEL. Consider a ported MSD Atomic Airforce Intake and definitely get a tune regardless of intake or not. A quick internet search for the Tampa area and other forums it would appear that shop.tampatuning.com is a reputable tuner and has experience with the LS7 platform. |

I went with Tampa Tuning for the calibration work.
Phil did an outstanding job tuning my car. Only one I can recommend in the Tampa area.

I understand now I think. I'm not very mechanical. How about these tuners?
