Is it true that for turbo cars one could get more HP from taking off mufflers? If so, then what do I put as far as a "muffler" do I get a SLP resinator or leave it without anything? I thought it was illegal to drive without a muffler but that's why im asking. imp:

It could give you acouple extra hp. It really just removes back pressure which helps your turbo spool quicker resulting in better throttle responce. I would do it just because I dont Give a F***.

+2038794 for open down pipe!!

I dont think it's Illegal to run without a muffler as long as the car is quieter than the ambient traffic noise...lol yea I got a ticket for that running open headers...

fern your running a flowmaster now, great sound looks good with duals, however a flow is a TERRIBLE muffler for a turbo car, open down pipe make most power, its gonna be loud as hell any fumy as a MOFO!!!!! take off thst flow put a dynomax bullet muffler, itys a straight through style muffle none restrictive, it give it a different sound, my turbo stang sounded good with it, the way yours is set up now its choking it dowm to like inch and half, i ran a 3 inch down pipe with a 3 inch dynomax bullet muffler all the way back, sure mustangs look good with duals but performance wise thats the way to go, my stang made 575rwhp :headbang:

Andrew made a very good point, flowmasters kill power on any boosted engine. I went through at least 5 set-ups before finding one that sounded good and didn't kill the power in my truck. As far as straight exhaust I run no mufflers on my Stang and have never had any problems.

We have a great exhaust guy right here in LL who can hook you up.

Thanks guys for all the advice i've been really scratching my head on this one. Chupac what muffler guy are you talking about?

Your car isnt loud at all then.

I ran a open down pipe on our car and it was loud and I think it sounds like shit. But that's me. I had flows on it at first when I took the flows off I could feel a BIG difference in power and spool time. So I would stay away from them I ended up putting a Moroso Spiral Flow mufflers on it I love them and the really hush the car down they give a very deep sound . I am only seeing 3psi of back pressure with them at 18 psi. at 9 psi I see no back press. at all.But like said above turbos love straight through mufflers

Open downpipe ftw. I love hearing the turbo spool. Cops usually don't harass the bigger motor loud guys. I've been running loud V-8s for a couple years without ever getting in trouble for it but Trey's STi with open downpipe got pulled over every week. Guess cops just don't like them 4 bangers.

They didnt like the Cobra when I had the blower either.

lol you obviously havent heard my car. Its the loudest thing on the planet when I lay into it.

maybe they just don't like you in general. What was the name of that cop that used to like follow your ass around?

I've never had a problem with the ig:'s and my shit is loud. imp: Maybe it's 'cause you look funny. :drunk::stoner:

 

[IronMan]

My stang picks up a dyno verified 53 rwhp when I open the cutout. I run bassani straight thru mufflers when the cut out is closed.

 

[LittleMT]

Maybellene has no mufflers, just striaight pipes...

she isn't extremely loud driving normal, but when WOT she sounds like a NASCAR...

A open downpipe works good and the turbo usually muffles the exhaust enough that you could get by with out the popo's harrassing you, but if you want a muffler anything but a chambered muffler would work good. the dynomax ultra flows work really good, the magna flow magna pak mufflers are good as well. They did a wright up on the turboforums.com about muffler choices with turbo cars. The switch from a flowmaster to a dynomax is surprising.
