summit brand mufflers??

[bigblue09]

what do you guys think about the summit brand mufflers? how do they sound in regards to flowmasters or magnaflow??

[HAULIN IT]

I put a pair of the (2 1/4") fully welded ones on my beater truck. Pretty much stock 350, with cast iron manifolds... They sound odd to me, a little rumble at idle, as you give it the gas (especially going up hills) it makes this resonant, gargleling sound in the mufflers, it has tailpipes turning out behind the wheel, so really I wouldn't have expected this echoing noise. Maybe on another engine or bigger ones are different, but would not be my pick. Lorne

I have a pair of the 2 1/4" on my truck
a bit too loud for my taste
even with an 'H' pipe
They did have an odd sound as others have noted
That went away with the 'H' pipe

They are well built
and won't expand or split

I know you didn't ask about other mufflers, but I installed a Thrush welded(chambered) muffler on our dually and it sounds exactly like a flowmaster.  It's around the same price as the summit welded mufflers and looks similar too.

try looking the x pipe kit that Chris sells on this site. Can't beat the price unless you cut and bend pipe yourself.

You would be better off getting a system from Summit, it is a dynomax setup, and they are cheaper.

As CCZ144A said, we have x-pipe kits, but they are for long tube headers.  They will work with manifolds, but you have to have downpipes made.

Is 2.5" the size you recommend? I see it is the size you sell but a lot of guys that like to go 3" but i never knew if that was the right size for a street truck that wont be making crazy power... would there be anything to gain from using 3" over 2.5"?

For an L05/350, 2.5" True-Dual would be perfect for a Stock to Mildly Built Engine, anything bigger would be "Over Kill" and a Waste of money(You probably would see a Performance decress, since your engine would be struggling to exhale that much)...  The Only time I have ever seen a 3" system benefical to a Stock to Mildly Built Engine, was when it was a Single Exhaust System(Entire Setup from the headers/manifolds to the muffler and out), or Even a Single to Dual Outlets(From the Headers/Manifolds, to the Muffler, and Split Out)..  Those systems were usually put on 88-98 C/K trucks, and the Third & Early Fourth GEN F-bodies....

Personally for any streetable 350 2.5 is going to be fine.  For a 454, 2.5 should be fine also.

[Skunksmash]

Hmm, how much HP/Torque would you say is ok to use with a 2.5" setup? I mean, what's the max before you would go with 3"? I ask because i do have some other mods in mind and i would not want to restrict the engine to much.

Any Big Block I ever built needed 3" exhaust to breath. If you are going over 450HP 3" will be a good idea
