I currently have a flowstopper on my T/A and Ill be turbo charging it over the winter. Im wondering if there is a muffler out there that is single in/dual out that will not kill me like the flowmaster would. Thanks

SLP loudmouth.

Single in, dual out, friendly with turbos...

Is that clip with a turbo? Sounds mean!

You can hear the turbo and the BOV, how is it at idle I have the factory SLP CME exhaust and it is already too quiet without the turbo on.

(p.s, what else you got on that photobucket page?)

I run a magnaflow catback. Not sure on the efficency but its a straight through quite muffler

I have a direct replacement from Spintech... I wont use anything else. Previously N/A was 399rwhp uncapped/385 capped through the Spintech and it sounds great too.

The Hooker and Magnaflow are great or you could run the borla adjustable and just run no block off plate so its running straight threw the passenger side tail pipe for best flow.
Or like mentioned something like a loudmouth/Rumbler being straight through would flow best just louder

Not sure if you are aware of this or not, but Spintechs do not flow well. Have you you ever looked inside a Spintech? Its like a rat maze. They are too restrictive..I know from experience, I used to have one. You might as well get a Flowmaster. It will flow just the same as a Spintech but cost half the price.

The Hooker Maximum Flow mufflers have worked really well for us. We are installing them on this GTO. have improved the fuel efficiency as well. I'll let you know what I find out on the gas mileage. http://www.exoticperformanceplus.com...Car.php?car=11 Bob

I have a Mufflex 4" system with a Spintech dual 3" out. I had heard that Spintech's were restrictive so I put dual electric cutouts in expecting a big gain. I went from 762rwhp/749rwtq to 772rwhp/764rwtq. I think that proves that it actually flows pretty damn well + it sounds as good as any I've heard.

The Spintech mufflers sound cool but the ones I've seen are chambered and that restricts flow. Flowmaster sound very cool but are restrictive even for 400rwhp motor combinations.
