Here’s a good online store. Reasonably priced and they have a full selection of mufflers, including Magnaflow and Flowmaster plus free shipping.

Just tell them to replace the y-pipe. You can pick one up your self for around $30 - I know magnaflow makes one becuase I used to have one.

They should have one, or be able to get one. If not, call Troyer performance or another vendor who carries Magnaflow. They'll have what you need.

Y-pipe will optimize flow so that the interior diameter of the tubing is the same thru-out, it won't open things up beyond what the rest of the tubing is.

Muffler won't really affect flow all that much IMHO, the rest of the tubing is what's important.

I'm not 100% sure what style you'll need. SOmeone smarter than me should be able to tell you, or your muffler shop. Or just go to Magnaflow's website and see what they offer for your car, then use that model number to order the paart you need.

 

if your doing a single inlet and a single out let on the muffler from ebay just get the inlet on one side and the outlet on another, it will obviously work then and u can find a way to fit it... my truck had enough room under that i havea center inlet and dual outlets and still have room around it with a heat sheild.

 

A little advise, from experience. A flowmaster 40 series will not give you more performance than a glasspack. There is no magic inside that creates HP. The 40 series is just the most cost effective muffler available that provides the least amout of restriction. Borla makes similar mufflers but they are twice the cost, however they provide a much better sound. So when it comes to compairing the glasspack, flowmaster,magnaflow,and gibson, you are payin for a particular sound. A glasspack WILL be the least restrictive of the lot. It will also be quite a bit louder than the others. A 30 series flowmaster would be almost as loud as glasspacks, but it is a racing muffler and is illegal for the street. If you are looking cheap and dont mind a little extra music from your tailpipes, and are looking to minimize restriction. GO WITH THE GLASSPACKS!!! The worst that will happen is they will be too loud for your tastes. I have ran an open exhaust on one of the trucks and it still wasnt all that loud to me. I got great gas mileage, but the motor was sluggish as hell. It is a fine line on not enough restriction and too much. Too little and your ECM will always pick the problem up and in return make both banks run rich, or at least attempt to. When this happens all the gas you were trying to save is still being used but now you run the risk of damaging your engine. If you go with the setup your talking about youll be fine. I went true duals, with no mufflers at first and loved the sound. But I didnt have my cold air intake yet, and had poor torque because of that. So like a moron I took someone at fords advise and restricted the flow with 40 series mufflers. Now that I have the air intake, I have removed the flowmasters and man what a diference. Sound is awsome, get about 16 in the city and about 19 on the highway. And look at the size tires I am running.

 

The least restrictive muffler is Magnaflow, it has a straight through design unlike a glass pack that is stuffed with glass wool and IS restrictive.

 

Magnaflow makes a glasspack, and several other style muffler. Could you be a little more specific? The guy is looking for a cheap alternative, not the mercedez of mufflers. And a glasspack is NOT more restrictive that a Flowmaster 40 series. I would be glad to research the info to prove that one. But since I have used both on the same vehilce, I can assure you that I am correct about this one.

 

Check out the pic

Magnaflow muffler is the straight wide open performance muffler with smooth deep tones. First and foremost the Magnaflow muffler was developed to be a superior product line of performance mufflers. Wide open performance Magnaflow mufflers outflow OEM chamber style mufflers by as much as 16%. This reduces engine heat and backpressure and improves exhaust scavenging from the combustion chamber. Magnaflow muffler minimizes the power robbing effects of the OEM system to restore torque and horsepower to the engine. From aluminized steel, to polished stainless steel, there probably is a Magnaflow muffler to suit your desire.

here is the price list

 

the link above my post right here shows a diagram of a magnoflow muffler.

Take a look. It has packing as well.....

 

The packing is around the “straight through” pipe for it’s acoustic value; the pipe itself is totally unobstructed. Before mine was installed I looked through it; nothing in the pipe, nothing.

 

Yeah, I'm sure there are other, similar designs. But I'm just ffamiliar with Magnaflow, and if you hold it up, you can see straight thru it.

 

I spoke to the muffler guys today. They said that flowmaster is ALOT more perofmance efficient than a glass pack. They said glass pack is 50yr old technology and it is not anywhere near flowmaster.

I let him know of the factors ofthe price is only what people want to hear. The tones will be different and that's what you paying for.

He explains no...

Anyhow we get on the subject of the Y pipe.

He says that is PURE BULLSHlT.

I told him a buddy (meaning you, but he doesn't know of the site, never told him) of mione redid his and explained on how it helped. And how you said that you could barley get your fingers etc through.

He says " That is full of shlt, the pipes go from 2 1/4 then hit the y joint which is 2 5/8 " and stays that size. Its so small of a differance that you would notice ANY differnce in ANYTHING..."


SO is he right or what the hell is he saying...?

Thank bro....

 

All I can tell you is, we pulled mine off and it was really choked-down inside. The exterior of the y-pipe was not indicative of the restriction within it.

I replaced mine after reading a what a member at another site had found. He noted the restriction inside his y-pipe. I replaced mine when I had my first exhaust system installed (I figured for $30 why not), and sure enough I discovered he was right.

I held it in my hand. Don't know what else I can tell you. My my thumb would fit into one opening inside, with not a lot of room to spare. Not even close to a 2" opening. The other opening was a little larger, my thumb fit easily into it with room to spare.


I can't tell you about glasspacks and whatnot, but I think a flow-through design (like a Magnaflow) would be more efficient than a design with internal baffles like a Flowmaster, but again I really doubt one muffler will yield a huge HP improvement over another.

 

i love my flowmaster and i am replacing the y pipe soon, my cousin did this and his was right around 2inch if not smaller threw the hole in the pipe!

 

Cool. I didn't think he was 100% sure but he sure talks like he does. He said that the Triton V8's are quiet by nature and there is no way to make them loud. Then just won't do it. They'll get louder than stock but not like other types of vehicles.


He probably just wants to sell me some ****...

 

BINGO!!!!!

I found one on ebay... Check it out. These are only $20 (s/h included)..

Is this what your talking about? These should do pretty good huh?

Thx
