Forgive me for asking another exhaust question; I know there are tons already posted. I searched and couldnt find this answer.

I have a 2003 1500 4.7 4x4 reg cab. I'm looking for new exhaust. Could you recommend something to me? Preferably $300 and under.

Post your thoughts on Straights, Glasspacks, and other types of mufflers. Thanks for helping a newbie.

 

Hey, I have a 04 QB with a 4.7 with 3" pipe cat back with a flowmaster with a single outlet like stock, sounds get to me. Got it all done at a local shop for less than $200.

 

I have the HEMI, I got an Air Force 1 cat back exhaust...it was about $350, with the chrome tips...extreme setup (comes out of the corner by the bumper in the back)...it sounds REALLY good on my truck...just a thought...

 

I don't think straight pipes are a good idea because you'll loose alot of back pressure causing a lose of low end torque all for the sake of being loud. Glass packs would be your cheapest route I would think but a flowmaster 40 series muffler can be bought off ebay for around $65.00 and they sound good too. I've got a 40 series with dual pipes and 4 inch tips and its plenty loud for me.

 

Ever here of the AeroTurbine? Here is a little info about it....

Universal Application

With sizes ranging from 2.5" to 5", whether you drive a sport compact, muscle car, SUV, truck or diesel, you can guarantee there is an AeroTurbine for your application that will reduce your vehicles exhaust temperatures (EGT's), as well as increase it's power, torque, and fuel economy, while reducing engine wear and tear.

Revolutionary Design

The AeroTurbine is a packless, straight thru design, high performance muffler. The company spent over three years in Research and Design to develop a muffler that used the Principles of Thermodynamics to reduce temperatures (EGT's), increase horsepower, torque, fuel economy, and reduce engine wear and tear. With it's fully welded 304 Stainless Steel construction, the AeroTurbine is nearly indestructible and guaranteed to last as long as you own your vehicle, backed by a manufacturer's lifetime warranty. Weighing in at a mere 6 pounds, the AeroTurbine is a natural choice for the performance minded enthusiast.


Learn How It Works


As the exhaust stream enters the AeroTurbine, it expands to fill the cylindrical chamber. This expansion slows the exhaust stream, creating a lower pressure at the inlet or scavenging effect, similar to that of a header. The exhaust stream is then split via an airfoil cone with an orifice similar to a conical jet engine. The outer stream accelerates to a higher velocity as it flows around the cone and has a lower pressure than the core stream, which is traveling at a slower velocity, and a higher pressure. The two streams are reintroduced via perforations in the center core. The high pressure inner stream is initially drawn out of these perforations as the gas attempts to equalize the pressure differential between the two streams. As this occurs, the change in direction of the exhaust stream causes destructive interference, which deadens the sound. As the pressure is equalized towards the rear of the canister the exhaust gas is pushed back through the helically arranged perforations in the center core, which spin the exhaust stream, causing additional sound cancellation, reducing turbulence, and creating a vortex that enables the gas to more efficiently exit the muffler.

This revolutionary design has been tested and proven to flow more exhaust gas than straight pipe. The quicker you can draw spent gases away from your engine the more power it can make.

Race Proven Performance

The AeroTurbine muffler has stormed onto the race scene with great success. From Nascar, to Rolex Series Grand Am cars, to being the official muffler of UROC, the AeroTurbine has become the muffler of choice for those looking for the ultimate in performance.

After the Rolex Grand-Am Series tightened noise restrictions, the Chip Ganassi team requested mufflers from several leading manufacturers, including AeroTurbine. After testing all the mufflers on their race cars they announced the AeroTurbine was the muffler of choice for the team. "We are now using AeroTurbine mufflers exclusively on our Grand-Am cars. They simply outperformed all the others we tested. They are lighter, fit great in the room allotted to them, and the best thing is they make horsepower," said Jeff Lohman, assistant engineer at Chip Ganassi Racing.

AeroTurbine mufflers have also been adopted by Riley Technologies and the SunTrust Pontiac Teams, who both compete in the Rolex Grand Am Series, after testing the mufflers on their cars.

Brandon Riehl who races in the Nascar AutoZone Elite Division, and most recently Rusty Wallace are also both using the AeroTurbine.

 

I have a few hook ups as far as Muffler shops,etc....

But I had this done for $75BUX!!

40 serie's flow
single in single out with dual tips

It's loud!!Does have the dreaded "Drone"@ certain Rpm's,But,I like it!

If you run it out farther back I'm sure the "drone"would Not exist!

 

Thanks for all the replies. I was personally leaning toward straights because I'm looking for something loud. Is the flowmaster 40 series loud when comparing to straights? I definatly don't wanna lose back pressure though.

I've basically narrowed it down to Flowmaster 40 series, Straights or Glasspacks.... Between those could you give me some guidance?

 

I would definatly steer clear of straight pipes because of the lose of low end torque. If you want the loudest I would think that glass packs would be the louder than the 40 series but my 40 series with 4" tips is plenty loud for me..

 

I have the Flowmaster 40 with dual 2.5" straight pipes and 4" stainless steel tips and it sounds great. I didnt notice a loss in low-end torque but I probably wouldnt know the difference anyways. It cost me $300.
