Exhaust Question

I have the Ida exhaust on my car, removed the baffles as they call it...

Did you do this after receiving the exhaust or order it without the baffles?
 
Most baffles are just steel cones that can be places/spot welded in the exhaust and cost about $20. You can insert these into any exhaust. From a standpoint of cost of materials and value the Accufab cost more to make and is priced lower. The fact the x-pipes are a performance upgrade over an h-pipe design should make this an decision easy for most.
 
Has anyone tried to ceramic coat the Accufab or Borla? It should reduce heat and keep the metal from turning yellow. I am having the Borla tips coated (because the chrome was yellowing), but I was thinking about sending the whole unit in for heat reduction.
 
X pipes are not necessarily better nor worse it depends on many factors. Yes Accufab is lower priced but not as well constructed based upon a myriad of comments at the Detroit Rally from those that saw both side-by-side.

As to baffles, they are not always steel cones and cannot be inserted in the middle of the Accufab or Ida exhaust only at the ends.

It has been beaten to death too many times. At the end of the day you will probably be satisfied with the stock, or the Accufab, or the Borla, or the Ida or the Ford off-road, or something else, its a personal preference.

This whole thread is exhausting.

Bart.......I removed them after getting the exhaust! The exhaust had 4 metal screens in them, placed in a certain order! To me, they looked like more of a source of restriction than anything else......and I wanted it as free flowing as I could make it....

Also lowered the underhood temps a good deal as well.....and reduced over 40lbs off the rear of the car!
I would suggest an aftermarket exhaust, whichever brand you go, for those two reasons alone....

Having been involved with a tuning shop that installed several hundred x-pipes and h-pipes I have yet to see an h-pipe outperform an x-pipe. All mustangs come with h-pipes and the most common upgrade for sound and performance is to upgrade it to an x-pipe. I was at the rally and saw both the Accufab and Ida's exhaust. They are both high quality, polished stainless. Very nice welds. Given the higher cost to build an x-pipe than an h-pipe, unless there is something extra in Ida's exhaust that he hasn't shared with anyone, I would bet the Accufab cost more to build. While I did not claim the Ida's exhaust used the $20 inserts, I know many people who add them and get the same overall result. If he doesn't use the commonly available baffles, what does he use? I guess everyone has their own opinion, but if it were my money, I don't think you can go wrong with either one, but I would lean towards the Accufab...

ASASN...Did the baffles you removed look anything like this:

Here is the lowest prices I can find on h-pipes and x-pipes and they aren't even stainless...see the comparison..most companies seem to making x-pipes and very few make both now....

lthl......no, it's not a cone! It's more like a screen type deal.....imagine if you will "waffle" fries, place four of them on top of each other in a specific pattern, then insert them into the pipe......

Best way I know to explain it........
 
Thanks. That acutally sounds like a less costly solution than the cone. Were they at the end of the tips and did they look like discs? Maybe a pic would help
 
I personally do not think there will be noticeable difference in HP in the cat back designs (H vs X), Both do have weight savings and better heat lost. For many of us who are looking to purchase one, the quality or quantity of the sound is the deciding factor therefore all of your comments are helpfull!! These systems are not cheap and even worse installation is not easy!! I am looking forward to DAVISP and EVERETTO experience with there new "H" systems

Its a disc.
 
I find this x-pipe vs. h-pipe discussion quite interesting, when none of the GT cat-back systems I have seen are really an h-pipe at all. Look at a traditional h-pipe "under car" system - it usually is simply a cross-connecting pipe for two parallel pipes that are quite far apart. The GT systems by their very nature have two pipes that are very close; one system has them actually touching/connecting (the x-pipe) and several others have the pipes an inch or two apart, connected by a very short piece of tubing (the so called h-pipe systems). It is quite easy to see that either of these systems on the GT are so close in volume, exhaust pulse sharing, and flow, that I see very little practical differences, relative to traditional x-pipe vs h-pipe discussions. Additionally, all the HP claims I have seen to date are only in the 10 -15 HP range (NOT including what one may "get back" by reducing engine compartment temps), and in my opinion the reason for adding any cat back system to the GT is the sound, the weight and the potential heat reduction - not the HP. At any rate, this is simply my opinion after studying all available exhausts, and I will be happy to report back once I install my "h-pipe" system.

I orginally wanted my Acufab Hot Coated. They were not willing to do it without having done a set as a shop prototype. I have had many hot coated headers and exhaust systems. I would think it is a good thing to have done.
