Thrush mufflers vs Flowmaster
« on: May 22, 2010, 03:16:10 AM »
I want to build a new exhaustsystem for my truck ,surfing arround i saw that the mufflers from thrush are cheaper than flowmaster, do you guys have experience with thrush?
good or bad, sound , performance...?

i want to go for the welded mufflers from thrush or the flowmaster 40 serie
2 pipes going to the rear and each with a muffler .
what would be the best choice?

I prefer the tail pipes exit after the rear axle and turn L&R I used to use thrush mufflers when I was younger and had no money but they never lasted and always lost their tone. Flowmasters sound great, but if you look on summit's website you'll see lots of options

I love the tone of anything I've put Flowmasters on.  They've never lost their tone or lost structural intergrity.

Flowmasters are horrid for restriction in the exhaust system. Google flowmaster and restriction, you will have lots of reading. Get Dynomax for a nice sound and free flowing exhaust.

If you are against flowmaster check out the Edelbrock mufflers

Yeah, that is true. If you really want good flowing mufflers, look towards what the turbo guys are running. They seem to find the best flowing mufflers. Usually Dynomax and Magnaflow.

Just finished my exhaust today. Dual 2.5 with H pipe, 40 series, sounds awesome! Got tired of the Magnaflow sound.

I think they flowmasters sound good, but they are pretty restrictive.  I don't like the drone they have at certain RPMs but other than that, they sound good.  If you're looking for a free flowing exhaust you can do something like the Borla XR-1, PYPES Race Pros, Hooker Aerochamber muffler, or the bullets.

There are a lot of 10 second cars out there running Flowmasters.

i saw a gearz where they put a flowmaster up against a cherry bomb vortex on a flow machine and the flowmaster only flowed like 2/3 what the cherry bomb did.

Comparing a muffler that is straight through vs a muffler that has baffles is ridiculous. Of course the straight through muffler is going to flow more. I think people get Flowmasters for their sound, not flowing capabilities. Granted, Flowmaster is better than stock, but something like Magnaflow is going to flow much better. My truck came with Flows, I switched to Magnaflow, and just switched back. It is all personal preference.

I was giving more options.  I have flowmasters on my truck, i dont like the drone of them at certain RPMS.  No need to get bent out of shape.  I seen another post where less restrictive mufflers were brought up. Why didnt you jump on that post?  I'm done
