first, Welcome, 2nd, do you have emission test where you are at? some of the people on here have the long tubes, O/R pipes, and flows so they would be the best as to telling you how it sounds, Me personally I don't like flowmasters but thats just me.
and just for parts your looking close to about $800, I ahve no clue as to installation.
heres something written by another member.....
It alldepends what you want in sound
Do you want to wake the dead
Have people put their windows up at stop lights
Piss neighbors at 1 AM
have a nice agressive growl
Be a sleeper and let no one know you are coming
Any performance muffler will sound better than stock. I had a great article up on the types of mufflers but with no spin. But it seems to be gone But I will hijack it from another forum. I have Dynomax Ultraflows and they also sound good. but the best thing for you to do is find what is best for you.
There is so much confusion on what mufflers people shoud get I thought I would discuss the different types of Mufflers and brands to look at.
The type of muffler determines the sound and performance you get. The brand is more for sound.
There are a few catagories of mufflers to choose from
Glass Packs: these are common among some of the older crowd they are like cherry bombs and they are very loud
Turbo mufflers; These are common amongest the general public they are made by many companies and are usually inexpensive and are offered at any muffler shop The best in this catagory is Dynomax Turbo Mufflers They have a nice overall sound.
Flow thru mufflers: These these are mufflers like Glass packs and that exhaust flows straight thru the muffler for less restriction and are mellower then glass Packs but have a great overall sound and really light up when punching the gas pedal. Dynomax Ultraflows, Magnaflow and Borla are in this group. these are all great mufflers but the borla can be pricey. None of these mufflers (Drone) at highway speeds.
Dynomax Ultraflows: they come in welded or stainless. they have a great sound I have them.
Magnaflows:I would also recommend they have a great sound
Borla: I would only use Borla's if I had performance heads and cam they are great on V8's but unless you got great mods they tend to get ricy at high RPM but they are a great quality but at a high price.
Chambered, Baffled, walled or deflecting mufflers: These are mufflers that have a maze of walls built in them to redirect exhaust gasses thru the mufflers to generate some backpressure but mostly to manipulate the sound giving you a deeper tone. Some of these are quite loud inside the car. The low exhaust pulse traveling thru these chambers or diverging walls will actually cause a druming effect giving you a (Droning) sound that penetrates the floor of the car and can make your driving on the interstate unpleasurable. there are a few mufflers in this catagory.
Flowmaster: unquestionably the most popular in the US. They have several series the most popular being 40 2 chamber, 40 3 chamber and 50's. Of all the mufflers 40's are the most popular and the loudest they are the Drone standard for all mufflers. The drone is especially bad in 94-98 mustangs. People either love them or hate them.
40's 3 chamber have somewhat less drone but not by much. 50's are quieter but are more expensive but have a good overall sound.
MAC Flowpath: they do not drone and is my favorite in this group. I would highly recommend them and they have a great overall sound.
Spintech: is another good sounding muffler in this group they also offer a nice side exhaust system but it to can be pricey.
These mufflers are what 90% of the people on this and most 3.8
forums have. There are others but they are less popular.
I hope this helps
