Oh yeah. They are some of the best flowing available.

 

i prefer my dynomax bullet...woot straight thru...can't beat it

 

Alot are like that. Magnaflow, Borla, glasspacks etc etc.

 

any body ever use spintechs thinking bout trying them on the truck and ditching the flows

 

does anyone know if hooker aerochambers is a straigh through design?? I cant seem to find a pix of their design??

i just orderd my hooker maximum flow muffler to replace that crappy flowmaster i have

 

Well then how does the corsa hold up??? I'm thinking about getting one. I saw one in person @ a dealership (Joe Gibbs truck) and I like the looks of it. It looks alot better in person than on the net.

 

Kinda sorda..



I got nothing bad to say about Corsa other than the fact they costs soo much. Power gains arent gonna be any more or less. IMO they make a great product. But what comes with that price tag is a name, sound and a muffler that got alot of R&D to devoted to reduce resonance. No one muffler on their cat-backs is the same, period. Thats why they dont sell a universal muffler. I wish I could find the picture of an actual cut away Corsa muff. It has a MESS of tiny chambers but yet the muffler is straight through. The illustration Corsa has on their site does not even do the muffler justice. Ill stop typing now.

 

well, i keep hearing people say how bad flowmaster's suck, but here's my thoughts.

i am not a fan of these sorry *** single in dual out systems. either go true duals or dont bother in my opinion.

here's a test i did on my own ride...the cuda. this was w/ my old motor, a 12:1 hydraulic cammed iron headed 440. ran 11.40s at 117 mph on the motor.
it had a pair of 1 7/8" primary hooker headers, full 3" exhaust system (w/ crimped bends by my exhaust guy, not mandrel bends that everyone thinks is mandatory) w/ a pair of old style 40 series 2 chamber flowmasters. this was through full tailpipes, factory exhaust tips, etc. it ran the exact same ETs and MPH through the full exhaust system as it did w/ open headers...and i did rejet the carb to try and tune it in, no difference. same night back to back test at the track.

this system was not a restriction until i put the current motor in making roughly 100 more hp and turning another 600 rpm. so i upgraded to a 4" system w/ Flowmaster top 10 race 2 chambers. guess what? no restriction.

maybe i just keep getting ahold to superduper hi performance flowmasters that arent avaliable to anyone else?

those old original 3" 40 series flowmasters are now on my truck CHIP
