I've decided to do my first "upgrade" to the Stang. I know I want the FlowMaster axle back exhaust and the Eibach Pro kit.

I just can't decide which one to get first ..................... Which would you buy first?

NOTE: I'm not looking for any engine performance upgrades yet. I want to get the car looking and sounding right first. Also, I've already looked at other exhaust and spring options. The ones listed above are what I'm going with.

Go with the Flows first, I got mine first and love the sound and look you get from them vs just looks from springs.

Have to go with the Flows my man.

I have both but since you want to chose one now and one later I'd go with the springs first. The reasons being that he car sounds decent with the stock exhaust but looks like hell sitting 9 feet in the air. Before I lowered it I wanted to enter it in a tractor pull. Hence the springs first. Then save your money and add BASSANI axel backs and a new tune of your choice. (I have the PREADATOR). I have the bassani's and love them. The Bassani's will cost 650.00 and the tune will run you about 400.00 Oh, I almost forgot the Steed CAI will run you about 300.00 That added a huge difference to my can and something you can do at your own pace. No hurry.

Without question you should go with the springs first .

you can do both... if you want to... i spent 320 bucks on a slp loudmouth and a friend spent 80 bucks at the muffler shop and his car is alot deeper and a little bitty bit quieter than mine... honestly i like the way his sounds better than mine... he just got them to do a muffler delete and got some magnaflow 4' tips that were 12' long... sounds awsome... if you can swallow your pride and get a generic exaust for a third of the price and get the same thing... its not loud at all at idle and interstate speeds, but it growls like hell at WOT... just my 2cents...

now whats the difference between the american thunder and the flowmaster cat backs besides having 2 mufflers and about $120 dollar price difference?

Flowmaster only makes one exhaust for the 2005-2006 Mustang GT. It's just called the American Thunder series. It's an axle back exhuast. There aren't any cat back exhausts for the 2005/06 that I know of.

This was my initial thought too. I do like the sound of the stock exhaust and as it doesn't give any real perfomance enhancement to change it out so I was thinking to get the springs first but then I heard the Flowmasters........... and now I still haven't decided. Looks like 5 for Flows and and 3 for springs so far, funny, I thought it would be the other way around. I was sure more people would say springs first as you said.

Springs 1st for all the same reasons everyone else stated. The sound is already good, and changing it won't give you any additional performance. Springs will give you appearance and handling improvements. Sounds like a no brainer to me.
