Axle back in my opinion is on of the best mods you can get and the most popular. I would just figure out what type of sound you are looking for. Though SLP LM's are loud but do you want raspy. The Ford Racing ones sound great and correct me if I am wrong are made by Borla. Which will give you a deep tone. Bassani makes a great exhaust to. So just find some sound clips and think about how you want to it sound. You will get no noticable gain by them at all. You honestly probably wont even notice a new mid pipe except for the sound unless you go force induction.
I would say go for a good axle back and get a custom tune. Tuning seems to be the best thing that you can do for these cars. If you have a canned tune save up and get an aggressive tune. 4.10 gears are great to. A short throw shifter, Clutch, Flywheel all make great mods. Also another huge thing that I am big on is building your car for what you want it to be. Dont get to excited and just start buying mods. I lost over a 1000$$ cause of that. I went with a supercharger only months after I bought my CAI, Performance Chip, Custom Tune (some places will make you new tunes for life all you have to do is email them or go to them and they will update it) Strut tower brace (wont fit any more) all of those parts are just now sitting collecting dust. So think long and hard what you want to build up.
I have to agree with most of this. I too spent a lot of extra cash on mods I thought were important at the time. In my case, most of the mods, especially the visual mods, I had a plan for. Hence why my car is coming along nicely. However, I too have spent money on mods that are rapidly becoming dust collectors. I was one of the foolish ones to buy a throttle body and TB Spacer before finding out about the minimal gains from them. I am still using the TB, but have since removed the TB spacer. I bought the polished strut tower brace and the custom plenum cover (neither were cheap), but now I am seriously consider going with a Saleen S/C, so either or both of these mods will have to go.
If cost is an issue, there is no real reason to purhcase some of the well known mods...i.e. the axel back exhaust will change the sound (presumably improve), but do not add significant gains (without other mods). The TB will improve throttle resonse, but the gains are minimal (if any) compared to the costs. Steeda UDPs are great, but pricey because they carry the Steeda name (same with Saleen and Rousch). Laslty, some mods give you what you want, but are not street legal, especially if you are in a smog state, i.e. California. So you should plan out your car and its mods, and figure out what exactly do you want. Some on here (i.e. 5-20, kj_cinci, etc) want or have eseentially street legal race cars, while others is really into the car show quality cars; and others want a fair mix in between (i.e. mrvandermey) the street legal race car and the show quality show-car.
You should definitely plan out what you want and work towards that goal.
On another note, I have a question, is a Brenspeed tune (where the tuner asks for what I have on the car and what I intend to put on the car then makes the tune) considered a cusotm tune or a canned tune?
