What did you do to your truck today!

[mud.man.rj]

Are the spintechs louder than Flowmaster super 44's, maybe less chambers or something to be so loud.

After more than five years of having my project on standby(got married and a bb) i started my truck and it fired on the first try.(fresh gas) But it would not move, check the trans fluid and it was full of water. You can see my avatar pic that was like 6 years ago we got hit by a hurricane. Will I have to replace the trans of just the fluid and filter?

I have spintechs on my 2004 z71. I was told that some guys from flowmaster went and made their own muffler, not 100% on that. I would compare them pretty close to 2 chamber flowmasters or the 40 series....They sound pretty good and the noise level is about the same.

Tow it to a fluid change place and have them "Power Flush" it, that will get ALL the fluid out of the converter as well as the tranny. Make sure they change the filter, too.

I'd check the engine and rear gear fluids, too.

Truly, my truck is not loud, unless i want it to be!! I have no drone in cab and unless I floor it and really drive the hell out of it, the tone of the exhaust is great, smooth and even.... its even better when I drive the hell out of it tho....

The guy that did my exhaust had a 69 in his lot that had super 44's on it and after mine was done he asked if he could compare the sound... after hearing the sound from the spintechs and his super 44's... he said he will change over ina year or so. He wanted to "feel" like he got his money Worth on the flows...

not sure, who the guys where who made the design, but I'm sure glad I bought them... stands outs in the crowd of v8's on flowmaster juice.. Spintechs are as "tinny" sounding.. if that's even a word. Flowmasters have that thin high sound at the peak of the tone, where spintechs do not.

Here are a few videos I found that I have posted in the past, not the best, but you can hear what you need to in them.

Sound sick. What engine? And which spintech? Looks like sportsman 3000

This truck is very quiet (no, seriously) compared to mine. Based on the "walk around" video, but especially the "short cold start garage" capturing the sound in the garage, I'm surprised how civilized your truck sounds. My computer is fairly high end and Bose sound system is pretty decent and I think I'm getting a realistic "listen" to your truck. I guess I need to get ahold of a video camera to be able to realistically compare the two truck sounds.

Also, let's clarify something here...I'm not opposed to the sound of my truck, it's just the raw decibel level is fairly high. Everyone that sees/hears my truck just loves it. But, as an example, I live about 30 miles from work and I generally don't even listen to the radio due to the exhaust from the truck.

A couple of things I noticed is your exhaust appears to be a little smaller, but it also exits at the rear tire. My exhaust turns down right in front of the rearend and I think it keeps a lot of the sound under the truck!

Wonder where I can borrow a camcorder???

[bcubed]

Added a side post battery quick disconnect to the bagged silverado so I could disconnect the battery when it sat for a while

[wrwelton]

Tried to install antennae, but they sent me the wrong one. Bummer. Resplicing the steering harness next.

[GRX]

Replaced my broken under-dash brake pedal return spring. Was a bear to get to.

[dhaymaker]

Tried to get my camera's video capability to pick up the sound of the truck. Apparently there was some serious tonal distortion and the sound was not good at all. Tested my phone to see if it would work and it was marginally better. So, let's see if I can embed the little clip I made yesterday.

Here's the sound from the headers, 3-inch pipe, and SpinTechs...

SpinTech w/3 inch exhaust - YouTube

After hearing the recorded sound of my truck, it helped put the AustinScott videos in better perspective. My truck does have a good tone, maybe it's just my ears!! lol

[Hotrob72]

started the install of my drop. Started in the rear last night, removed shocks, springs and the upper spring brackets so far......

[Fldawg]

Going to finsh up my rear disc conversion and finsh replacing front metal brake lines , but the prebent line i bought is gonna make me remove drivers side header so i can get it in. should have done all this before i finshed the truck,

[mud.man.rj]

Spintech 3" exh sounds good dhaymaker, but with exhaust it really comes down to the cam and you def have enough, sounds really nice, better in person I bet.

[rsavage]

Finished replacing the 200 4R with a TH350 in my Burb. Road tested it and it seems to work well.

[longbed67]

Got my engine mocked up to make sure all the parts will fit... looks like i will have to do a little trimming to allow clearance for the bolts.

[longbed67]

dhaymaker that sounds awesome!

[Fldawg]

Hey longbed looks good always wanted to do that to a straight 6, i really like to hear that when you get it done.

[Red68]

I installed some arm rests from a 55-66 chevy truck and new sunvisors that I ordered from Classic chevy parts. I also cleaned up a A/C control panel I bought at a swap meet a couple weeks ago. Also test fit a new bench seat and new foam, taking it to an upholstry shop next week.

[longbed67]

Fldawg I will definitely post up a few videos when she's up and running!

[lmac1210]

Took out radiator, fan housing, headlights, and then after a lot of screaming stopped because of the stubborn bumper...I know it can be removed, just not today

NICE Truck!!

The exhaust on my truck when I first put it together exited under the truck (turn-downs before rear axle) it was to loud in cab, so I had the current setup fabbed up that exits out the side. The sound in cab was cut in half.
I bet if you just had the end sections re-done to exit out the back or rear you would be much happier with the exhaust note.

The engine in the truck is a head swap 327.
Spintech's = Sportsman-3000 2.5" in/out


These videos where taken only a few days after getting the exhaust put in.
They have had some time to "mature" (fill with carbon) any they are a tad bit quieter now after a year or so of running with an overly fueled engine.
