Black04SSS

Yeah it isn't so bad running 92 octane for now until I can tune it, but when you do the math it adds up in a hurry if you drive the truck a lot. I just don't have the right cable and software for tuning this thing and will have to borrow from a friend that has it when he gets back into town. I listened to a bunch of clips online of different exhaust systems and I really didn't like how raspy the Corsa sounded. It sounds great for a performance car or truck, but I want something a little more mellow sounding - just a little louder and much better flowing than stock. The clips I watched of the Magnaflow stuff seemed right where I am wanting my truck to sound. It still has stock manifolds and cats on it, so if I want louder and more performance in the future, a set of LTs and high flow cats (or no cats) would give it more exhaust note as well. I have to admit that going from that obnoxious Thrush stuff to the stock cat back did make it too quiet for my taste though . Even on a DD.

Hello everyone. I'm a new member to the SilveradoSS.com forums, but not new to tinkering with LSx powered vehicles. I found the forum while doing some searching for a few things on my SS. A few weeks ago I traded in my 2000 Z71 for a Black 2004 SS AWD with leather. I'll post some pics soon, but it's filthy right now since winter has returned to MN again..lol. It is stock for the most part though. I did replace the gold Bowtie in the grill with a polished AL one, and it has ventshades and a rollup tonneau cover on it. The truck had a drop in K&N filter, ungodly loud dual exhaust with Thrush mufflers, and since it pinged like crazy on 87 octane, I suspect somebody messed with the tune. I had a K&N FIPK on my Z71 that I took off and made work in the SS. I had to tweak the metal heat shield to make it work, but the rest was the same. I guess the core support is different - possibly for a bigger radiator on the 2003+ trucks? Anyways, I am running 92 octane for now until I can mess with the tune. I don't care to spend the extra money on gas for a daily driver vehicle. The exhaust was just too much for me and a friend happened to have a freebie stock cat back from an SS so I had that put on. Unfortunately the muffler had a loose baffle and rattles like crazy, so I am back to needing to mess with the exhaust some more. I like the stock tailpipe look, and I want something just a little louder than stock, but not too loud. So after looking around on here, I just ordered a Magnaflow 12599 muffler to replace the damaged stock one with. I don't plan on anything too crazy with it (haha, that's what everyone always says in the beginning, right!). Like I mentioned, it's a DD for me. I've got a 99 Trans Am WS6-clone with cam and heads and lots of other stuff, my wife has a 98 Trans Am WS6 with bolt ons, and then we have an 87 Trans Am GTA that is a drag car project and we have done all our own work including the tuning on all of them. I included plugs and wires in the muffler order from Summit and then I will be doing brakes all around and flushing and changing all the fluids as well soon. So anywho... hello!
