What Is a good free flowing straight through muffler that doesn't rob power, im currently running flowmaster 50 series mufflers
Do people ever search before posting questions?What Is a good free flowing straight through muffler that doesn't rob power, im currently running flowmaster 50 series mufflers
Sounds good. But...Mkrantz1106 – What is it that you don’t like about your Flowmaster 50 Series mufflers? Straight through mufflers don’t necessarily flow better than Flowmaster mufflers.
Just because the Flowmaster isn’t a straight through muffler, doesn’t mean it robs power. It does quite the opposite. The internal design of a Flowmaster muffler manipulates exhaust pulses that come from the exhaust valves opening and closing. The design actually increases flow that actually increases velocity through the muffler. There’s a lot of science that goes into the internal design of a Flowmaster muffler to make it outperform other mufflers on the market.
Yeah flowmaster is just trying to back up there product on this one.
Run a magnaflow- dynoma ultra flow- borla xr1- pypes race pro
All of those are good sounding quieter straight threw designs

It's widely known/told that flows hurt power on turbo cars.
Not true? Throw out your pictures/theory and show proof.
Dyno/track comparisons between your muffler and competitors on the same car. Post results. Make it public. Video it.
If what u claim is true then it should've been done. People love the flowmaster sound. EVERY single forum has people posting they don't flow. They lose power.
Posting the sales brochure won't change that!

Interesting first post.To get the best performance out of a chambered Flowmaster in a Turbo application, you need to upsize the muffler diameter .5”. This makes up for the changes the turbo makes in the exhaust pulses.
These Pro-Series mufflers have proven to be awesome performers in Turbo applications.
The outlaw is just another bullet. Flowmasters big seller is their classic sound. The outlaw doesn't sound like like that. But. It will not rob power like u said.I bet the flowmaster outlaw would work well since it's like a straight three dyno max bullet but would be very loud.
That hushpower may work well too in a half size larger . I wonder if
The hushpower I'd a straight threw or a swirl style like Moroso spiral flows
I completely agree. If it had the stock flow tubes and tails on. Those things are dented and kinked to ####. That could make a difference in it self. I infact just switched out my stock pipes that surrounded my mufflers for 2.5" madrel bent pipes. Im also going to the dyno on October 15th for a club dyno days. so I be running the same as before with only a piping change. We will see then if it makes a difference. But this does nothing for the fact of Flowmaster VS other brands on turbo setups. That's why all Flowmaster would have to do is front me a catback kit with a upsized chambered mufflers and hushpower mufflers along with some dyno cash. Then I'll dyno test and document the difference in results back to them and all over the forums. Don't get me wrong I would love to run some Flows on my car, but I too was one of many who made the change to a straight though design when switching to turbo. I currently run Pypes Race Pros.The power gain could have been a result of the change to 2.5 mandrel bent exhaust/tail pipes, the new mufflers or a combination of them both.
Good point. :salute:I clicked your link and found this:
"The current exhaust consisted of some really, really old 2.5" flowmasters circa 1991. Apparently that is all that was installed because it looks like the tailpipes are still stock 2.25" units."
The power gain could have been a result of the change to 2.5 mandrel bent exhaust/tail pipes, the new mufflers or a combination of them both. Check out this pic from the thread. Whoever installed the flowmasters did a terrible job:

I am no flowmaster fan but this guy's results don't prove anything. If you want to know for sure you'd need to dyno the car, swap mufflers and nothing else, dyno the car again.
A post in this thread would be a great startI have 3 chambered Flowmasters on my TT notch and like them. You always hear that "flowmasters suck for turbos" but I never felt like my car is down on power with this setup (stockish motor-GT40ps, edelbrock peformere intake, all smog intact: 420/502 at 10 psi). That being said, I am running a 2.25 catted H-pipe into a 2.5 inch Flowmaster catback. It sounds really mellow but nice. I inherited the system when I got the car as a 4 cyl project. The fit is way way better than the brand new pypes system I got for my 97.
It would be interesting to see if the notch picked up power with different mufflers but somehow I doubt it.
I would like to hear more from the flowmaster rep. It is in their interest to dispell this myth if it is one....
