Thrush 17658 Welded Muffler

Bought 2 for my 94 Caprice. I had wanted to upgrade from stock mufflers for a while but didn't want to spend to much to do it. The priced looked to good to be true so I figure if they looked to cheap or flimsy I'd just return them. Upon opening them I was surprised they looked well made and durable. I wasn't looking for extremely loud or obnoxious and the tone on these was just right for me. Also drone noise is low compared to other brands I've used in the past.

Loud and droning from a cold start, but these sound better and better as they heat up. More mid range tone, not as throaty as a 40 series, little rasp. Tone is much more pleasing when you arrive at your destination and let it idle for them to hear. Can’t beat them if you’re building on a budget.

I ordered this muffler on a weekend with the super saver free shipping and received it on Tuesday, it took 2 business days. soo glad i didnt waste the money for expedited shipping. It is installed on a 5.0 304 with about a 4 foot tailpipe and a .45 degree turn down, (on an old jeep) This muffler has a much deeper tone than a flowmaster. (yes, i have owned both) The tone is the smoothest, cleanest sounding tone i have heard by far. Theres none of that throat gurgling water sound or popping and crackling, its smooth and deep and its not too loud. My neighbors hated me for a while, i had straight pipe at first, this muffler has it at the perfect pitch,tone and decibel.

Using these on my street rod with on a 350 with headers, a mild cam, Edelbrock manifold and Holley 4 barrel carb. The sound is great with a really deep, throaty rumble. Overall they are a great sounding value priced muffler. I highly recommend them for a similar setup.

Installed on my 305 powered ‘91 Caprice with no cats. Nice, low rumble without resonance. May only last a couple years but for this price I’ll put another on when this one rusts out!

Read the comments an reviews before I purchased. Not bad for the price and what other brands it relates to. Bought an installed on my 2011 Nissan Frontier SV v6 and it sounds pretty good. Actually sounds better than I thought it would. Great item for the price.

I had these installed on my 94 cadillac fleetwood 5.7 they sound pretty good .Deep mellow rumble . only the slightest hint of a performance muffler at idle. Hit the throttle and they roar. I cant comment on interior drone because i still have my factory resonators on . If i didn't i imagine they would drone just a bit. Best Bang for your Buck.

Good quality part but LOUD, I had to add a glasspack to quiet it down. Even with a catalytic converter .

Its a 2 chamber muffler, so no surprise, but its too loud for anything other than a drag or show car. Price is right and finish is good, but you'll need a resonator or a car that still has a catalytic converter in place. Too loud on my c3 vette with long tube headers for any normal driving. I'm wearing earplugs until I can try another muffler.

They look and sound great. Haven't driven c10 truck yet.

Killer sound for 1/2 the price of flowmaster.... Happy for now .... Only time will tell how long they will hold up though ... But I think they should work out allright
