Thrush Welded Muffler - 1999 Silverado

[slowride55]

Do you think this is a pretty good choice for a muffler?

[BREEZEONE1]

Did you see a slight improvement in your MPG after you put this on? Do you wish you would have put on a flowmaster? I cant see what the diffrence is other than price. Your truck sounds great!

[realj4ck4ss]

what the engin man ??

[fossilknife]

check out my exhaust i have the same set up as you

[tsmth334]

Yeah I have the cats on

[TheSLEDNUTZ]

you have the cats on it or no

[G2SKIER]

Sweet sound once revved up but too "hollow" for my liking at idle, you can fix this by running the tip out before the rear tire and eliminating the extra 5-6 foot of piping(it looks badass too)

[dirtybnick]

exact same setup i have on my 99 well worth the $35 i paid for it

[TheChrisExtreme]

did this help your gas mileage?

[ChevyZ71djd]

sounds great but is there a way you can get dual pipes with it

[PLUMPER101]

i got thrush on my 90 silverado 1500 why do people buy flowmasters again? lol

[215rant]

would that sound good on a 4.3l v6?

[PrairieKid03]

@215rant yes.... yes it would:D

[ziegelbauer]

@215rant yes i have these onmy chevy s10 blazer 4.3 sounds great

[951prerunner]

@ziegelbauer so what typs of sound is it producing with the blazer? is it a deep kinda muscle tone? and is ur blazer stock besides the muffler? thanks if u reply..

[ziegelbauer]

@951prerunner yea its got a good muscle tone and its all stock

[bigj0384]

would love to see some video of normal accelleration - i'm EXTREMELY confident this is the setup i'm going to go wih on my 2005 sierra - my buddy's already got the thrush on his 5.3 silverado - we both brun k&n intakes and his sounds pretty damn killer -

Would that sound good on a 4.3l v6?

[chevymangabe]

I have a 1 in two out version of this exact same muffler on my yukon w/ 4" tips....I love it!!!!

[ssj02]

I have borla mufflers and it sounds close to this one.

[bhecht08]

Can u hear it at all when your in cab driving? and how much louder than stock would you say it is? Thanks for the replies.

[tsmth334]

@bhecht08 I can hear it in the cab fine with the windows down, but not much with the windows up. It's not much louder than stock at idle, but when you start it up and when you give it some gas you can definitely hear it roar.

[bhecht08]

hey whats the exact model of this thrush muffler? i was thinking about getting one for my 99. thanks

[tsmth334]

@bhecht08 It's a Thrush Welded 3 in 3 out.

[jackassmanhole]

sounds great man

[SpeedRacer942]

this is exactly what im gonna do with my 99 silverado 5.3 i have had the muffler sittin in my garage but didnt know if it would sound good. this just did it for me

[tsmth334]

i used 3 in and 3 out

[tsmth334]

glad i could help

[yamarocket05]

what size inlet/outlet did you use?

[tsmth334]

I know not bad for how little the cost

[redbonedavekkk]

surprisingly sounds pretty good for a cheapo autozone muffler lol
