Fosscore's 2006 Tahoe Build Thread

[Fosscore]

I decided to add a few more videos of the Flowmaster 50 series muffler for my own reference, but also so other guys could hear what it sounds like on my truck's 4.8L.

One is with the windows closed and one is with the windows open. Sunday morning early is always good for no traffic.

Changed out the Vapor Canister Purge Valve this morning to hopefully clear the following codes noted below.

I had the codes cleared 2 weeks ago with my mechanic, but the CEL came back on, so fingers crossed that is all it is.

Could a bad seal on the gas cap also cause that?

 

[Fosscore]

Yes we checked the gas cap first. Then we checked this part. He said sometimes it gets blocked, but you cannot blow it out.

There is another part of the system (I have not researched that far yet other than one video online) by the fuel tank that will be next on the list if the CEL comes back on.

Truck sounds pretty mean for a 4.8! Maybe I need some driving clips too haha.

Oh and picked up some of that 303 you recommended... loving it so far and a little bit goes so far

Sounds good. I see you hit 6,000 on the teach with the tow haul on! I have to post vids too. Mine is so loud, but I'm starting to like it.

Thx man. I always thought it sounded pretty good, but cool to hear it on video. And you guys driving 5.3 and 6.0 motors giving compliments reinforces my thought pattern to just keep what I have and get that damn tip welded on!!

Yeah I love that 303.

Thx man. Yes the RPMs were bumped up with the Black Bear tune and wth the Tow/Haul ass mode on makes it a bit more fun to drive.

Yes yours sounded pretty nasty. Like that Cigarette I posted the other day. And of course the cam loping along. Sweet!!

 

[Cattivo]

Sounds great brother, It seems you forgot to mention that it was filmed in Mexico...we would never speed on public streets

If code 455 comes back then check the evap vent solenoid. I'm a service consultant at our local chevy dealership and our tahoe's are known for these problems.

Where would that be located?

I can't get enough of this exhaust! Lol, I gotta share it. This was after it was done, and just letting it warm up.

Thx man. Speeding?? Lol
Only to satisfy the boys here on TYF.

Sounds great. Almost like looking at my truck. I'll take that sound and 6.0 thank you.

Just doing my part, but at least it's only a detailing potion, not something super expensive right? lol

hey man, this is helpful. as mentioned the local cost of a flowmaster vs a venom 250 is the ultimate deciding factor. do you have 3" all the way or stock piping?

@inmypassatlife

Glad to help out. I have seriously considered changing out my muffler, just to scratch the itch of wanting something new. After hearing the videos and posting here on the TYF with good replies and taking it to the muffler shop with the same input, I am pretty set on just getting a tip welded on to pretty up that exit point.

My piping is all OEM except whatever they needed to do when they welded the Flowmaster on initially.

This is the double tip that I am considering putting on. It has been posted by other guys and is pretty much the same tip as the SLP Resonator Delete kit that applies to the NNBS.

 

[TheAutumnWind]

Well that doesn't make me feel too bad about my 12 combined in my 4wd 5.3

No kidding. I was getting ~12mpg combined on my 200k mile 6.0 AWD XL without a tune and with mechanical fan.
