I thought you said build a race car, lol. Who do I look like, Big Chief, lol? Supposedly that's a Pontiac 482 in the "CrowMod". It's gnarly though.

UPDATE: Testing was delayed as Murphy was in town the last few days. Our welder gun trigger took a dump and on the way to go pick up the parts, the other truck with the GM Borla system got rear ended at a stoplight. Perfect. To add to it, the V-band clamps we ordered to make changing the mufflers out easier haven't come in yet. Our plan was to fit the pipe upstream and down of the muffler in the truck with the V-band clamp M/F pieces. We ordered a set for each muffler also. We're going to weld pipe to the inlet/outlet of the muffler, if need be, to make up the length and offset differences and attach the corresponding V-band pieces to them. That way we could literally swap the mufflers in and out in a few minutes. So, delayed but certainly not discouraged. The welder is fixed and ready to go and the V-bands will be delivered tomorrow and we'll get cracking. The truck that was damaged that was to be our basline/constant for comparison only received minor damage and the exhaust was not harmed. So we're going to try and collect our baseline measurements and videos today before it goes to the body shop for repairs.

 

P.S. Kye Kelly got that a$$ drug by Birdman (Gary Weatherly) this weekend at Kennedale.

Was about to order a muffler for my Denali, then saw this thread a little while ago. Been waiting to see these results before I order.

 

Thanks! Cant wait to see/hear the results.

Out of curiosity, which muffler were you going to order and what was your plan? And is that your '69 in the avatar?

I was planning on going with a 14" magnaflow.

 

Yes it is my Camaro. LS3 / T56 hoping to boost it over next winter.

I cant wait to see the the results either I am looking at either the magnaflow catback system or the Borla Type S catback system. Also looking at the Volant cold air intake system. I live East of Houston in the mont belvieu area. cant wait for the videos. Also does anyone now a good place to get a Spray in bedliner?

Well, she's gorgeous. You've clearly spent the $$ to make it what it should be. Sh*t, I know what a set of those multi-piece wheels run, they're not a game. Good for you. Boost? Snails or blower? I'm certainly a fan of excess, but I'm sure you've already got a healthy cam in the LS3 and that alone wakes it up to let the gear grabbing while looking out of the passenger window begin. (Sigh) but alas, our quest to twist frames never ends.

We technically will not be testing an off the shelf catback system from anyone, but instead designing our own in hopes to replicate the desireable sound levels and frequency ranges people love so much from the GM Borla system. Other than the tube itself smoothing out air flow, dropping a better filter in the stock airbox will yield almost identical results. If they would just sell you the tube and elbow, it would do exactly what you need using the stock airbox.

 

I can't vouch for the Mont Belvieu area, but there are some places on the east side of Houston that do excellent work, reasonably priced and have been around forever to stand behind their work. One is in Baytown called John's Trim Shop and the other is a touch further west called Brian's Tint Shop. A quick Google search will find them in seconds. John's may be a bit higher on their pricing, but they do meticulous work. Brian's caters more towards the guys who build show trucks, which also means they do meticulous work. Start with those 2 and see what they quote you.

LOL yes its quite the money pit. I enjoy it, but definitely put more into it than I should. Its neverending. I feel like after I boost it I will be happy with it (ive said that before). Im not sure yet on direction, but probably turbo. Appreciate the compliments.

We are heading to pick up mufflers this morning to begin testing this weekend. We will take baseline decible readings from my truck, which has the stock exhaust but is lifted with a mild mud tire and there IS a slight hint of tire noise. We already took measurements from the truck with the GM Borla system. We will only be running a handful of Magnaflow mufflers this time. So far we plan to pick up a 12256/14256 and a 12226/14226 for the 5.3 trucks which are the same mufflers except for inlet/outlet size as the 12259/14259 and 12229/14229. Are these the most common numbers folks are considering? Thanks.

      Towing In Loose Gravel

      By Chuck FB · Posted

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Towing In Loose Gravel

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?

      The use of absolutes like "always" to describe gear selection, and giving free advice at a boat ramp sounds like a recipe for disaster. It's a boat ramp, not a farm, for starters.   IMO gear selection should depend on the obstacle. If low range is working and this is a slower speed, controlled ordeal, I'd keep using that.

      I had a boat for many years, never had a problem even with a 2 wheel drive 93 Silvy for 20 years. Good tires, proper use of the gas pedal worked.
