4.3L flowmaster 40 exhaust
I just installed the flowmaster 40 series on my 4.3L 1995 c1500 W/T. single in, single out flowmaster 40 with new tailpipe and stainless steel tip. stock 4.3L. stock cat. stock everything but muffler. 2.5" into cat, 2.25" in and out of muffler and all the way back to tip. sorry for bad video quality and putting computer so close to the tip. also i didn't rev it that high at all - barely tapped it, but since the camera was so close it might sound raspy. it's just the camera. you can't really hear it in the video but she sounds like a v8 at idle. my 85 k10 (350ci) sounds just as good swear to God. anyway its hard to hear on the video but i'm very very happy with the flowmaster 40 on the 4.3L vortec. ****truck now has magnaflow hi-flow cat, which isn't in this video.
