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

Рет қаралды 576,024

Күн бұрын

It's time to build an exhaust system on the 4.8 Silverado since open headers on a cammed LS isn't exactly streetable. For the exhaust I wanted something that would perform great both now and when the power adder gets installed, but also sound unique at the same time. This required at least 3" exhaust for the single dual sections, and 4" for the single section. I wanted to use one of my favorite mufflers of all time, the Flowmaster Hushpower Pro Series 4" but I had no idea how it would sound with both an X pipe and a Y pipe.

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.

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.

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.

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.
