Hopefully not before I'm dead.

 

This topic has made me rethink what I want to do, shorties or long tubes. My car is a daily driver that may or may not have a s/c installed someday. I don't know for sure but right not the answer is maybe. But, if the answer changes to yes down the road, having long tubes already on the car would allow me to get the most out of the s/c, correct? Even if I choose not to get a s/c someday, would I still see some benefit to having long tubes? I guess my only real concern is the long tubes making my car too loud. Any thoughts?

Your thinking is correct Long tubes are the way to go. If you go with a s/c later your that far a head of the game. And yes they are louder, depending on the mufflers you are using.

 

I have Flows on the car now. Would Flows compliment LT's? Not sure if a s/c makes sense for me. By the time I save enough, the 50th anniversary Mustang will be out!

IMHO loudness is a function of the muffler selected and the size of the exhaust pipe collector back. I have seen real quite cars with long tube headders over the years. I think this is a propogated misinformation myth.

Superchargers overcome other engine deficiencies by use of flow and pressure. With or w/o anykind of aftermarket headder you won't be disappointed, and the incremential value becomes less.

 

Yea, with high-flow cats, a good midpipe design and good mufflers it should still stay pretty quiet. I would think that the benefits of shorties would increase quite a bit with FI though, as does just about any breathing mod.

 

The bottom line for me is that living in California going with long tubes and losing the cats isn't an option. I don't have to be smogged until 2010 but if I decide to sell the car I would have to have it smogged and with long tubes it isn't going to pass. I'll stick with the JBA shorty headers and they are the only shorty that has a C.A.R.B. stamp as far as I know.

After the headers are installed I am going to have my car dynoed and with the mods listed in my signature I am hoping to bust the 300 RWH mark.

The pictures are of JBA prototypes before their final design.

 

I'm going to have JBA Shorties/ silver ceramic installed on my 06 GT. Honestly for the few HP gains of possibly 20 - 30 HP question, is it really worth spending $800 + $500 for install? Probably not but for me this upgrade is because I can't stand to look at my rusty cast iron x-manifolds. I'm sure this will help the KB supercharger in a small way but it's a minimal gain. The single best mod is the supercharger best bang for the buck! If your an HP junky save up for that then do those other things later. You maybe better off modding your suspension at that point then spending on those little HP gains. But it the end yes it all adds up right!

Paul, they can catch up all they want. By the time my car is 25 years old (the length of age for classic tags and NO inspection), I will have the 5.0 Cammer race motor in the car (or whatever sick hi-horsepower V8 Ford is offering for the car), and classic tags so NO INSPECTION & EMISSIONS TESTS!!!

 

Hey Johm, if you didn't get my PM back to ya, all I can tell you is Borla Stingers with ARH L/Ts sound downright SICK!!! Everyone tells me how bada$$ my car sounds!!! They all want to know what I did to it to have it this loud.

 

What is the RWHP you are pulling down right now?

 

No idea! Never had it on a dyno but that will change one of these days. There aren't any tuners with dyno's within 150 miles of me.

 

I was at the Mega Ford Weekend(Sept. 8th and 9th) put on by Brown Brothers Ford at Mission Raceway. With just BBK shorty headers, an o/r x-pipe and Flowmaster mufflers I dropped close to 3 10ths. My stock best time was 14.01 and with the exhaust I ran 13.73. With those kinda results I'd have to say they're worth it.

 

Sounds great. You also have to take into consideration for your drop in time to atmospheric conditions, temperature, humidity, etc. These cars run a heck of alot better when they are cooler. Your previous best time, was it hotter than it was a few weeks ago?

 

It was way hotter at when I ran 13.73, the 14.01 was on a cool night

 

nice drop in time!

 

Very nice!

 

in my research it seems the jba cat4award equal length shorty headers would still be worth it even compared to long tube.

though long tube has higher peak HP/TORQUE, the shorty add significant HP/TORUQE at the low/mid range which will be felt.

also from a cost perspect, you keep your stock cats/h-pipe so parts cost will be a savings.

i also have been hearing some issues when the stock cats are swapped out. issues that can be a pain in the ***.

so...if i do headers, im going to do JBA shorty equal length...

thanks!
