Good choice?

Davy03 · **Good choice?**

I ll get a Mac Fit Cat - Back Exhaust System, and I also will get longtube headers.

Is that a good choice?????

remeber if you get long tube headers you need a "longtube" H pipe.

But thats a good choice.

Danger Dude · 10-16-2003, 10:33 AM

Remember shorty headers are good up to 300 hp. So shop around for the best deals. And be sure to check out our vendors first like Extreme Effects

Long tubes rule im gonna get a set once my nitrous is in

Rellik · 10-16-2003, 10:39 AM

Iam getting a set of long tubes as well.

Danger Dude · 10-16-2003, 10:46 AM

very nice but but not a neccessity especially on 94-98 cars with good shorty headers. Unless you have a supercharger or turbo charger or you grow 2 new cylinders it is just not a gain. But if you just want them to be cool go ahead.

Even people with superchargers have shorties. You guys need to stop looking at catalogues and stop wishing for things that are not value added.

If I had a 99+ with crappy exhaust manifolds and I got a good deal on long tubes I would probably by some

MusclesFromBrussels · 10-16-2003, 10:52 AM

long tubes have been shown to give a good gain on 94-98 V6's running nitrous

Davy03 · 10-16-2003, 10:53 AM

I have a 2003 V6 Mustang. Would I really need an "H" Pipe?

Danger Dude · 10-16-2003, 10:54 AM

That is not exactly true the only gain comes with removing the cats or going to high flow cats, headers alone did not make a gain on a nitrous setup

Davy03 · 10-16-2003, 10:56 AM

I just wanna have more power and a nice sound. Would I need to get and longtube "H" Pipe with longtube headers?

Danger Dude · 10-16-2003, 11:00 AM

Here is the problem I see with your attemps at mods. Like most people you are going backwards. I would spend the money you want to spend on a cat back exhaust system first then get the P&P intakes and heads second, then go for headers and x pipe if you really want to. Because right now you will get almost no gains with a nearly stock motor

But hell that is only my opinion and you do what you want to do to your car.

but you did ask for opinions I just speak the truth with no Bull or spin

MusclesFromBrussels · 10-16-2003, 11:04 AM

Not exactly true but true. High flow cats and Longtubes on a V6 running nitrous will help over our stock shorties.

corey is right with ur mods u might not get anything but 1 HP tops. Long tubes r only really helpfull when u r making a lot more power via SC , heavy engine work,Nitrous

corey, they do add value. Not so much to stock cars (but thats how all mods are) Yes stock headers flow fine to around 300 hp, but i want to exceed that with my car

99+ headers pretty much flow the same as 94-98 headers they just look shitty. But they are made wide, and flow pretty well.
Iam getting longtubes for my new engine which will be done correctly.

Danger Dude · 10-16-2003, 11:14 AM

Well first Charles I was not talking to you

and no on the dyno the 99+ stock headers are restrictive with any power adder or head, intake and cam upgrade. They just dont promote good exhaust evacuation

Rellik · 10-16-2003, 11:17 AM


Quote: Long tube headers promote torque and horsepower. Shorties do the same to a lesser extent. I don't recommend aftermarket shorties for a near stock v6. Whether it is a 94-98 or 99 up. The 94-98 styles are a work of art for factory headers. 99+ are ugly, but big and flow well. If you're supercharged they might pose a restriction.-83v6carb

Davy03 · 10-16-2003, 11:19 AM

So should I get longtube headres when I wanna make some more mods to my engine in the future or should I wait with the long tubes?

And where can I find all the things that I want for cheap?

MusclesFromBrussels · 10-16-2003, 11:21 AM

Get longtubes later if u wanna run n2o or a SC or some heavy engine work. get just straight pipes or maybe an H pipe setup now and if ur an auto focus on ur rear end IE. Gears, Stall ect.

Rellik · 10-16-2003, 11:22 AM

no fighting dudes, this is all about knowing facts, corey iam not trying to piss u off either, so no hard feelings, just trying to figure it out.

I know that 99+ arent EXACT when compaired to 94-98's i mean look at this pic, their ugly. But the pipes are big and they do flow quite well for being from the factory. And compaired to 94-98's they obviously dont flow quite as well, but its very close. Hense why i posted mikeals quote.

pic of headers:

Guys I recently have had the opportunity to see first hand at the number of many cars being dynoed and looked at all the data. It is amazing what actual dyno numbers are being made and what is a waste of time. I use to be a avid promoter of CAI,s but after seeing hundreds of dyno numbers they provide almost nothing. I was supprised to see exhaust add almost nothignon a stock car or a UDP add 3-5 HP not the 10-15 as advertised. I am not through either in a upcoming post I will have complete details on bolt ons and what is useless. It will be a eye opener

Do not take my post personal. The question was asked at the beginning of the post and I answered it truthfully (just trying to get facts out thats what this site is about)

I dont keep spending money on mail order chips I have been on the dyno lately and am working with Pete and the dyno guy and all of this has been free. My experiences with this problem will help me convey to others the problems with mailorder chips

I have been building fast cars for over 20 years including my fastest car a 650 HP Z-28.

MusclesFromBrussels · 10-16-2003, 11:47 AM

I agree with u on the bolt on thing and i know ur a good guy and me and u r friends on here. No need to change that. Im just pointing out the impression that i am getting from you. No need to delete this we can have an intelligent discussion on here.

Davy03 · 10-16-2003, 11:51 AM

Thank you all for all your help. I really appreciate it and I am glad to be a memeber of this site.

Danger Dude · 10-16-2003, 11:53 AM

Charles you see the pic of the 2 types of intakes. The reasoning behind the long tubes being better ie thew same as the reason behind the 94-98 being better than the 99+ and it shows up on the dyno. The long tubes exhaust from the heads stay separated longer increasing flow and increase excavation of the exhaust meeting in the collector further down. The 94-98 headers have less length but still separate the exhaust into the collector increasing evacuation and velocity, but the 99+ the exhaust immediately comes out into a collection area like a standard manifold not allowing the same level of evacuation and flow and it does show up on a dyno

But enough of that also!!!!

Modding is a personal thing and I understand that. I say what I do from past experiences. I do not try to offend or belittle anyone. Modding should be fun and experimenting is also cool. After all it is your cars being modded. but when people ask I will give the most accurate answer best of my abilities.
