exhaust
 

hey guys & gals. quick question. i have a '02 GT conv and i am looking to change the stock exhaust on it. all i am going to do is change the mufflers. i have heard that magnaflows are a good one to buy and then of course you have your diehard flowmaster fans. personally i have been a flowmaster fan in the past. if i go flowmasters do i go 40 or 50 series? i don't want it too loud inside. or do i go with magnaflows. what is going to give it that deep everybody knows it's a mustang sound? all suggestions are greatly welcome. :)

If you go with flows, I'd go with the 40 series. I have the American Thunder flows, and that's a 40 series.

The 40 series will be louder than the 50 series. :)

Get a catback. A little more money, but a cheap install or a do it yourself job. Much more clean installation as there is no welding.

And you will get better exhaust flow because you will be going from 2 1/4" factory bent pipes (tend to have a crimping effect in the bends) to a 2 1/2" mandrel bent (with no crimps in the bends). If you want that sound, I would go with MAC or FLowmaster. If you just want loud, go with SLP.

flowmasters for sure you can always tell when a flow master equiped stang drives by

I agree, Flowmasters definately has the Mustang sound. I had what used to be called 3 chamber, which I think would be the 50 series. I now put on the 40 series with Delta flow. It is a little louder, but not much more than my old 3 chamber. I also have a convertable, and I thought the noise would be too much, but it hasn't been bad at all.
Good luck,
Brad

thanks for all the info guys. have another question for ya. what are some small add ons that i can do to add a little more horsepower? :)

took off my flowmasters yesterday and installed a set of quick-flow mufflers. 3" side exit, all i can say WOW!!!!
neil:D :D :D

50's are quieter
 

3 chambers are definitely quieter with out any, or at least much, increased back pressure. I use the 50 series and can't stand much more noise than I have now. Of course, I don't have any cats as I drive an antique (LOL).

K&N and a cold air kit, ignition, larger throttle body & maf, gears (not more H.P. but definitly the best "seat of the pants" mod), nitrous or other power adder, the list goes on and the price goes up.;) . I'm sure someone else will add to the list.

Well, since you said "small add-ons" I would say this is a pretty complete list:

1 - Gears (4.10s) - about $500 installed. No HP gain, but increases performance greatly. Like adding 30-40 hp.

2 - Under Drive Pullies - About $200 installed. 8 - 10 hp

3 - Cold Air Kit w/ K&N - $60 - $250 depending. 0 - 15 hp depending on which one and what you believe. The higher priced ones don't add more hp, just look better

4 - Plenum and larger throttle body - $400 or so. Easy enough to install. 9 hp...proven

5 - X Pipe. $200 - $400. 5 - 15 hp depending on the model. You need to research this depending on your other plans for exhaust.

6 - Chip or Programmer. $200 - $400. 5 - 15 hp depending on your car mostly. Autos see better performance improvement because these devices will help the way the car shifts gears.

7 - Nitrous. $400 - $1000. Safely up to about 100 hp. Biggest bang for the buck.

All hp values are actually rear wheel hp, so hp at the flywheel is about 15% higher.
