Thrush vs. Flowmaster mufflers
I have been a Flowmaster fan since I started driving and have had them on just about everything I have owned. I have read and heard the clips about Magnaflows and I am not sold on them yet. Seems you have to have a high power motor at high RPM's to get good sound out of them. I was wondering if anyone has had any experience with Thrush welded mufflers? The look a lot like Flowmasters but at half the price. My '81 is just a weekend cruiser and stays garaged all the time. There were comments about their build quality but that was 3 years ago. My engine is the stock rebuilt bottom end but has Summit head and cam package plus Edelbrock EFI. I estimate its putting out around 300hp. I am planning to go to a true dual setup with Flow-tech ceramic coated headers, dual removable cats, an X-pipe, 40 series Flowmasters and just wanted everyone's input on these mufflers. I saw a thread from 2008 concerning Thrush mufflers but was wanting some more up to date info. Thanks!

I believe the HP difference in most turbo mufflers is neglidgeable. The small difference is at max rpm. I have Flows on my 68 L36 and don't really like 'em; while others swear by them. One thing for sure is they weigh about twice as much as many others (not so good). I like Walkers and cheapo muffler shop generics. Just my 2 cents. I'm sure you would be happy with the above exhaust system, especially if you like the sound of Flows...

The Thrush welded are the old Flowmaster series 30 models.
I hear Flowmaster let the Patent go and Thrush picked it up.
I ran a set on a 355 in a 72 Nova and have a brand new set sitting in the garage, I would use them.

I just put dual exhaust on my 75.
I went with Cherry Bomb mufflers.
they make my Vette sound like a Vette should sound.
I get a lot of complements on them and they are not loud at freeway+ speeds.
I ran them when I was younger and glad I tried them again.
Plus they were a lot cheaper than the other two guys.

I've got Thrust Weldeds on my winter beater LT1 Caprice. They were the cheapest mufflers I could find when my previous mufflers rusted out, otherwise I wouldn't have used them(not a flowmaster fan, but thats just a personal preferance). No signs of rust on them yet, and they've been on for 2 years. I'd recomend them to anyone who's looking for the flowmaster without the flowmaster price.

VERY cool! i've always loved the sound of a car with an x-pipe. another system i was looking at was the Pypes Violator. it's between factory style side pipes, an under the car chambered exhaust with an x-pipe installed or the Pypes system fortunately, that point in time is a long ways off still. i'm shooting for late winter to early spring before it's ready for the road.

They are all copies of the original Corvair Turbo muffler from the 60's. Walker makes an excellent sounding turbo muffler in 2 sizes that are pretty reasonable.

Also i have run both thrush welded and flowmaster and they both sound ok but the flowmaster sounds better,i think. i have also run cherry bomb pros ,flowmaster delta 40,flowtech terminators,pypes violaters and pypes street pros,dynomax ultra flows, on this vette .
