5.3 exhaust

chevy5.3 · April 5, 2006

What are most people gettin for exhaust on their 5.3? I have a 2000 silverado 1500. My exhaust goes true dual with 2 cats...then y's into 1 right after the cats...then goes to the big ass muffler and out with the stock pipe. What do you think i should get? and do most people have 2 cats on their 5.3?

No suggestions?

Yeah, 5.3's have dual cats, a Y then a single big ass muffler. I've got a the smallest oval magnaflow muffler possible on my 5.3HO and it sounds pretty awesome. Really aggressive, deep and sets off the neighbours mustangs car alarm.

I have an '01 Silverado EC, 5.3, 2WD. I put a Flowmaster " 70 Series " muffler on it [ 3" inlet with dual 2 1/4" outlets ]. The " 70 Series " muffler was designed for big-blocks and flows maximum air without sounding like an old farm truck with burned-out glasspacks! Flowmaster recommended not going over 2 1/4" outlets to keep from losing off-idle torque. It sounds good without being too loud, AND doesn't produce the dreaded " resonance/booming " at hiway speeds. The last truck I owned had headers, Turbos, and the 3" exhaust exited in front of the rear wheels. Quick, but WAYYYY too loud! I still think that the 350 small-block sounds better then the new-design engines due to the change in the firing-order. The Dodge Hemi sounds the best of all. You can tell it's a Dodge just by the sound.

Zoomers Exhaust for me

Just installed it yesterday and got it welded up last night. Easy in driveway installation for the novice backyard mechanic.

Nice low rumble on idle and acceleration, quiet when cruising.

Parts and workmanship look to be top notch with a lifetime warranty.

I to have the REALLY SMALL Magnaflow oval Single in/Single out on my 5.3 and it sounds amazing, deep rumble on acceleration, lope at idle and screams at WOT
