I've got quite a few friends who have flowmaster mufflers. 40 series and 70 series sounds great. Real throaty sound to them too. Rumbles at idle and sounds great all the way to redline. Not so loud they're annoying on a long drive though. Ive got some glasspacks on mine that were already on when i bought the truck, they were some weird brand but everyone i know who has had or still has glasspacks complains that once they start to get old you get an annoying rattling sound when the trucks idling or settles into overdrive. Sure enough, mine does that. Im probably gonna put on a 40 series flowmaster, or straight from the cat back (that way they check engine light aint on)

flowmaster super 40s sound exxcellent for those years of GMC and Chevys. I had mine installed with new pipes for around 230 bucks

I have a single in dual out 70 series big block II muffler. It has a real mellow rumble under normal driving conditions, when cruising it is just audible (the radio will drown it out easily). I bought a whole system for 300 dollars so I am not sure what it would cost to buy the muffler alone.

I just had mine replaced from the cat back in single and out dual....with flow master 40's. They sound great and the total cost installed was about $400 with stainless tips.

Past experiences have taught me that Flowmaster may cost a little more but well worth every penny in the long run. When you see how well they hold up you auctually save money in the long run!

I run the 2505 and the rest is in my sig...sounds killer good. Iv'e tryed alot of exhausts on my 02 and my 80 silverado and flo-pro"s last and sound the best IMO . Also there way cheeper than the others that are just a "big" name brand but suck.

 

Have a gooder :cheers::crackup:

I'm running a daul in dual out three chamber flowmaster with pipes all the way to the bumper. It has a very nice tone and I don't have to hear it when I don't want to. Cost was about three hundred installed.

I agree with the flow pro muffler. You know one thing to be positive on, is check out the rest of the exhaust system, including the Y pipe. I had exhaust changed out on an 89 with flow pro muffler and tail pipes. I was suprised on how good it really sounded till I went in for an oil change once, and they told me I had a dime sized hole in the pipe. I had it changed out and noticed the exhaust was a little quiter than when I bought, Most muffler places just do the muffler/tail pipes and leave the rest in tact. Well just think how old those pipes are before? Just making an observation. But all in all, the Pro Flow mufflers are pretty good and they are cheaper than the flowmasters. I paid 200 for the cat back right out the door for mine and was very pleased.

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...

      Different requirements for oil filters?

      By glenn27 · Posted

      // Thank you, also for your  response. More information is always good. This 2013 GMC is most likely my 'forever truck"-I'm 77 and retired...and truck only has 42K on it-very clean-so I try to keep it that way.  Tks again for your  response- glenn

      Alternate wiring for Kicker sub with Bose system. (DO THIS)

      By smooth68 · Posted

      I started my install this weekend. Everything was pretty straight forward but I ran into one issue with running power through the firewall. The nipple grommet on my High Country already has a small harness running through it - has anyone else ran into this issue? And on the engine bay side, does the wire basically just penetrate the factory wiring boot? I did this on my '22 Trail Boss and it seems much easier but thats been a few years. My other thought would be possibly drilling a new hole adding a rubber grommet just to the lower left of the factory hole. Thoughts?   Has anyone used a T-harness off the Bose amp and obtained power from there? It seems a little odd that such a small amp needs 3 power leads

      By glenn27 · Posted

      ///// Ok--Thanks for that info--I could not find yesterday when I looked for the specs on that NAPA filter what I wanted. Their website is not very user friendly. I buy all teh filters for  our three vehicles once or twice a year. Have always run NAPA Gold on everything I own....I buy it thru my Son's account for his business-which he has a Heavy Equipment repair shop-one reason he uses NAPA so much-they have such a full line of coverage for just about anything/anywhere- He gets s  good discount because of volume bought. Anyway-Thank you -Sir for your response.   glenn
