upgrading exhaust, anyone done it?

[randyb2004]

I thinking of replacing the exhaust on my 1995 K2500. At least a cat back system. Anyone replaced their's with something that sounds good but is not too loud. Truthfully I was thinking of a header muffler in place of the stock muffler and just a single 3" out. My 1989 Chevy has a hole in the pipe just before the muffler and it sounds real good, not loud either.

This forum looked lonely with no posts.

BTW, thew 1989 K2500 is for sale see, Craigslist in Allentown PA.

I had "true duals" with "Flowmasters" on a '96 Silverado I used to have. It sounded good, except for the "drone" inside the cab @ cruising speeds. I did gain some performance, but don't need the interior noise.

[randyb2004]

Every car/truck with Flowmasters I've known was loud. My 1989 truck has a Dynomax cat-back on it and was very quiet untill the hole developed in the pipe. If you want real quiet go with a dynomax. I'm looking for something with a little more "sound" to it. I'm just tired of listening to annoying rice burners running around. You just can't beat the sound of a V8.

I upgraded my 03 Sierra to a single Magnaflow with dual custom bent pipes and long stainless angle cut tips. It sounds very good and I don't get any drone. That's why I didn't do Flowmaster. I call the guys at Summit Racing and they gave me all the information I needed to make the right purchase. I get better MPG and more power too.

I have a 3 inch cat back with a Magnaflow on my 99 GMC Suburban and I am more than pleased. I thing it woke it up a fair amount .I know it helped with towing my boat.

We've got smog laws here too now...but. Buy dual cats/mufflers of choice. Find the shop in town that'll do custom bending. Shove those 3"ers right out the back (make that ol' 2500 talk dirty to ya) Or bologna cut out either side.
May I suggest some bady blue Walkers...LOL

I have a set of Flowtech Ceramic Coated shorty headers for sale. Never installed. I paid around $380 for them a few years ago. Sold my Suburban so I have no need for them. Just taking up shelf space. Make me an offer. They still sell for $329.95 in Summit. Will fit the following:
88–95 Chevy/GMC Truck, 1500/2500, 92–95 Suburban, 92–94 Blazer/Jimmy, 95 Tahoe/Yukon: 5.0L/5.7L, Tube Size 1.5" O.D., Ceramic Metallic Coating

Email Smokingreen94z if you have questions.

I found this post somewhere else if ya want to put headers on. LET's MAKE A DEAL (What is this a game show)
good luck

I put some Doug Thorley headers on my '99 2500 Silverado with a Gibson muffler, no cats and single 4" tailpipe. The engine is an '01 8.1L and the sound is awesome. It drones at 1800 - 2000 RPM in the cab. Too noisy for for my wife so it goes to the muffler shop Tues for some resonators. If it was just me I'd leave it alone but it sets off the neighbors car alarm when I drive by.

I put on a Borla exhaust system with 4" dual exhausts exiting right behind each rear tire. Supposed to give me an increase in gas mileage but we'll see. The advertised 20hp boost is evident especially on the low end. To me I'm not used to the resonating growl when I start it up, but I'm slowly getting used to it. By the way, I have a 07 Tahoe, don't know if that was the smartest thing to do but oh well. Would like to know what you think of Superchips flashpaq and what kind of filter is best?

[mr.copenhagen]

gibson has a good exhaust system out..iv got it on my truck its an extream duel kit..not too loud..but loud enuff..

[rmreid]

It's expensive but Corsa makes a great sounding system, quiet at idle but nice sound on acceleration ..another option would be a Flowmaster 70 series.

I thinking of replacing the exhaust on my 1995 K2500. At least a cat back system. Anyone replaced their's with something that sounds good but is not too loud.

if u want loud like wakin up people in other towns get the Purple hornie glass packs!! iv got those on my GMC with Hooker hedders and a 454 bb..they are soo loud haha but flowmaster super 40's are really nice

[Camo91]

I tried a new muffler for mine and went with a melotone single in dual out, the guy at the muffler shop told me that they were built better and were a thicker guage metal than flowmasters. They sound just like a flowmaster 40 to me, but I had my cat cut off so mine is pretty loud but not annyoing loud. Have heard them with cats and sounded really good too.

[95CTburb19]

im quite happy at the moment with my stock single 3 inch pipe with the hole in the muffler on my burb. It does sound nice, much better than the airy weird sounding pipes on my sierra 2500

[89suburban350]

i am getting a borla exhaust next week along with longtubes... plus they make great sounding exhaust systems

[randyb2004]

Well I finally bought a 3" in and out Magnaflow, I'll be putting it on soon, single 3" all the way. I'll post back with what it sounds like. Can't rush these things you know.

:sign0173: take pics if you can!

[dtalsma]

try Gale Banks, I put one of his exhaust systems on years ago on my 95 K2500 and have not had one problem not even a leaky header gasket.

[Doug C.]

I also went with Magnaflow , nice calm rumble until you nail it . I've had most of the big names on all my vehicles , Magnaflow has the most cival sound , plus also living in Pa. it 's stupid to buy anything other than stainless.

[JayMack75]

I just like straight pipes. I'm not interested in spending the money on something I don't have to. I want it loud...exhaust systems give a good rumble but not the LOUD I am looking for. So I went with straight pipes.

[randyb2004]

Exhaust is on, very quiet. I got the longest muffler they made, should have went with the shortest. I used all 409 SS pipe, the muffler is an older one, still has an aluminized outer shell. All the new Magnaflows are all SS. I'll get some pictures if it warms up around here.

[pino_55]

i have had aftermarket on everytruck and if your going to get somthing louder it's going to be loud most of the time unless you choose to Dynamat your floor boards in the cab. Just make it loud.

[Pete95Sierra]

there is no such thing as too loud... besides you cant help but smile when u gun it and everyones jaw drops around you... or they shake their head haha... wither way you gotta love it

[DarkRider89SL]

When the time comes im probably gonna go with either a Flowmaster 40 or a Magnaflow behind headers...
