I've seen dyno results where straight through mufflers made more horsepower than chambered ones, but I haven't seen any results on the effect on torque. I'm one of those guys who cares more about torque than horsepower. To me, horsepower gains have more effect on the top end, running flat out and wide open, which most of us rarely do. Torque is the usable stuff. Sorry if this is off topic.

 

Yeah i like tq its usable.

 

Went to do the exhaust but it was just to cold today

 

Even if a Blowmaster gave me more torque, the cab drone they create on fullsizes (dunno about Blazers, would think it's worse) and the fact they rot out so fast wouldn't warrant the gains. I know plenty of people who have swapped out their Flowmasters for Dynomax Bullets and found they had less drone... from a "race" muffler.

 

The drone on my flowmaster 40 isent bad at all. When i step on it its loud as hell too. When i had got my exhaust done i noticed throttle response right off the bat along with more low end so ive been more happy alone with that. Mine has really no rust other than slight discoloration and ive had it for about 2.5 years now and my brothers Suburban for i think 8 years and i live in NY where theres nothing but snow and salt more than you could imagine lol. I would love a straight through muffler like a Borla XR1 or a short magnaflow but no need unless this one comes into problems

 

i have the magnaflow hi flow cat on my cav, along with an 18" glasspack cherrybomb resonater with a walker highflow muffler on it. She sounds nice to say the least and has allll the response i want - granted a bit off topic but not full out. Does actually gutting, welding, re plumbing, and packing a stock muffler cost less than a high flow one would cost u to install? may just be worth more to have a proper built one rather than a stitch welded back together muffler.


Btw PaulO2288 - he lives in Sudbury Ontario Canada.... pretty sure he see's more snow and salt n dirt than you and i combined! lol. i hear u tho on the snow/salt shat being unimaginable since it down right bothers me how fast my black jimmy goes white from driving in town :/

 

I am going with a real exhaust. But i still plan on hacking up the stock one to see whats in there and show how to mod the stocker for some sound

 

so....if you're gonna install a proper system 9or even just the muffler) why are you gonna waste your time messing around with the stock one? never mind the BS with swapping them around.

 

Well us having about 5ft of snow this winter already alone with almost the same last year and this winter isent over yet im really happy with how its not rusted out. Also along with the fact that i practically take my truck out on the beach almost every day of the summer last year and this upcoming year unless hes on the beach also i think i encounter more salt/water than most and mine hasent really rusted out at all

 

Yeah i dont know if i am going to mess with swapping them around but i do want to cut it up to give me a project to mess with
