the MOST INCREDIBLE sounding exhaust EVER! 4.8 vs 8.1 shootout Pt.9

[@LawrenceTolman]

I just hope this exhaust works as well as it sounds. So close to getting this thing on the dyno again.

I want that exhaust when you go turbo

[@BrockGrimes]

21:06 man that sounds good. Would love to have that on my '88 c1500 with the 350

[@colinallan2976]

I ran mufflers and turn downs on my lowered 3500 7.4l dually for years, finally built full tailpipes and it completely changed the sound! Thankfully for the better. I can't wait to hear your 4.8 when its finished.

I love a big single exhaust. Sounds good on everything in its own way. My sister did a 4 inch straight pipe on a 4.0 grand Cherokee in high school. It idled like a Cummins and revved like an Indy car. Weirdest shit I've ever seen.

[@JPGenergy]

Had an old neighbor with a similar setup, just had an old diesel stack cut way down from under the rear door and somehow straight out and it rumbled from a mile away

[@boostedmaniac]

I had a friend customize a cone shaped intake for the 4.0L Cherokee back when you couldn't buy one. He made it from some PVC pipe and an open air cone filter for a Honda Civic. It had a pretty nice sound at high RPM. That with a magna flow exhaust and 5 speed manual, back in the late 90s, it was a sleeper.

Sounds great, everyone thought I was dumb for doing 3" single exhaust with a MagnaFlow 3" straight through muffler and a 3" dump in front of the axle. Mines very subtle until you stab it, then it really talks to you. My truck is stock with a home made cold air, stock converters and the 3" single custom made (by me) cat back exhaust. It's a 2000 extended cab 4x2 with a 5.3 and 4L60E. It's got 286,000 miles on it and I drive it daily. It's a super fun truck, sounds great and runs very very well. Glad yours sounds like mine and you like it. Great job, keep it up.

[@jaybrown679]

I am running the same setup as u except the muffler brand but I get a lot of compliments on the sound its suttle until you stab it next to the guy texting while driving and he drops his phone...lol that works for me

[@Eaglefreek300]

I had a vehicle with a 5.3L swap and it had single 3' with a Magnaflow and it sounded absolutely amazing. Unfortunately, the person who did the exhaust, did a horrible job of routing it. It was an off-road vehicle and I needed it redone for ground clearance. Went with a true dual setup and it sounded like garbage.

I’ve used C25 with TIG accidentally once. Wrong labels on two otherwise identical 250cf bottles. It burns up the tungsten very fast, especially on the sizes used on thinner material. I wouldn’t doubt it if that oxidized tungsten gets shot straight into the weld puddle either. So, no, it won’t work permanently. You’d be better off using the MIG on stainless than C25 TIG. Edit; Try it for yourself! As a hobbyist welder, I never even thought about it until that happened.

[@supersportimpalass]

I did basically the same thing on my 5.8 windsor. 2 1/4 to a single 3” x 12” long resonator into a holley single inlet flowmaster with dual 2 1/2” out the back. Sounds similar to your truck. I love it.

I had a 383 in an s10 once. 2.5" from the headers Y'd into a single 3." I used a huge RV 3.5" ID straight through muffler, then Y'd back into dual 2.5" tail pipes. Mild cam, so not too loud or rowdy, but that exhaust was super low sounding. Made it sound like a huge motor was in there, lol.

[@louisgonzalez6935]

A lil tip that helped me. They sell mock flex tubing in required OD tubing your using to get the angles and path desired. They fit tight around the steel mock set up and allow to manipulate how ever you need to find the right path to connect tubing. But , beautiful work sir!

[@BamaTidefan1967]

Its nice to hear an exhaust system that brings out the sound of the cam unlike that straight pipe, too loud sound that everybody seems to be going for nowadays. It sounds good now but I bet it will sound great when the tailpipes are added.

[@bluecollarfox913]

From the research I’ve done getting that “tuned” sound is all about making each side of the exhaust. 8-1 exhausts sound the best!!!! Or if you merge equal length headers immediately after the collectors into an c or Y pipe. Gives you a similar sound

[@TEAMWRIGHTEOUS]

Man, I've listened to probably 40 different muffler sound videos on these trucks over the past couple of days. Trying to see what sounds best. Everything has this sluggish truck sounds to them and I have always hated the way they sound. But this one has that old school small block sound. It almost sounds like the DynoMax Ultra Flows I used to have back in the day. This is definitely how I want mine to sound when I build my 6.0 I'm saving this video for the future and I can stop listening now. But I've got to find your videos once it's driving and hear it and I got to find the dyno videos to see how it turned out. 💪

[@rotaxtwin]

Sounds and looks great. I figured being a truck you'd have more than enough real estate, but it was actually not as forgiving as I thought. You did a nice job of massaging those pipes through all those (somewhat) tight spaces. And it sounds just fine! Looking forward to the first ridealong...

[@johnbarker5009]

I like the way you use material clamped to the truck to keep parts of the system positioned correctly to the vehicle. Sounds great!

[@LawrenceTolman]

thats the only way to do it for me. I've tried once or twice to do the sharpie mark and weld it outside the truck, but inevitably something moves around and wont line up properly. By clamping everything in place on the truck and getting 3-4 good tacks on each joint, you're pretty much guaranteed to have perfect alignment, which is critical when having 2 v-bands and no flex couplers.

[@jeffclark5024]

Looks and sounds great! I just finished up a cam swap on my O6 5.3 and I need to do a setup like this! On a side note, this last cam I did I had the engine out and decided I was going to put the engine flat on its back and drop the cam in vertically and it worked awesome. Horizontally I always seem to scratch the cam bearings just a little no matter how hard I try.

[@ogfromutube9649]

The black widow muffler on my 5.3 LS has a dual 3" inlet and single "3 outlet. It has 1 7/8 headers with vbands to an x pipe similar to the one you show. (May even be the same). So after the x pipe it has a 30" dual straight section to the black widow dual to single. With another vband flange on the outlet. Has a single 3" over axle and straight out. No cats but here in VT on a 1990 car it isn't required. It does sound pretty amazing. The 226/238 .600 lift cam definitely aids that and the tbss intake is pretty good as far as stock intakes go. With a trunion kit and pushrods it made 390whp and 395wtq.

[@bearwas_on_abike]

Just an edit to the x pipe explanation, the exhaust doesnt necessarily cross over, it mostly stays on the same side with a small amount of separation. The exhaust pulse hitting the point where they join does indeed help pull the exhaust from the other side. And for noise, an x pipe is an affordable substitute for equal length headers

[@dragracingrule]

I did this to my 04 Gto as far as xpipe to ypipe. Mainly cause I didn’t want to put the dual exhaust like 05/06. It sounded good and I was happy with it
