How much of a gain will i get

[MarkieSHO]

How much of a HP gain would i get if i slap a pair of Flowmaster 40 series on my 99? Just an approx guestimate is fine

 

[yamahaSHO]

You will gain more noise.

all of your friends won't think that V8 badge on the fender is just for decoration anymore. thats about it.

I don't think there are many mufflers out there that would give you a big increase in hp. But still get the Flows. I like that V8 rumble!

You'll gain the respect of many people who think your SHO is just a 'grocery getter.'

Aight thats pretty much what i was thinking anywyas.I definatly am going for the sound, was just wundering if any gains would be present.Thanks all! thumb

The way to REAL horsepower gains is through the proper implementation of bright red "Type R" stickers and Double Decker wings!

Straight up Dawg!!!! I'm thinking about breaking the barrier and going for a TRIPLE DECKER WING!!!!!

Or maybe just this.....

Wings are not my favorite item. Even the little one on the back of my SHO kinda makes me laugh sometimes. The only thing it does is make the trunk lid heavier and fall down on my head every now & then so that I say words like, "Poopie" & "Fudge Stick" (I've got a 4 1/2 year old that repeats ALLOT so I have to watch what I say)!!

You mean the angle of the brim on my ballcap does not gain 7 hp? Darn. And that ball cap cost me $12 too...

wink , pax, smn

 

[SHOGHOST]

Does anyone know what size the inlet and outlet is on the mufflers? cheers

 

[MarkieSHO]

Well i was thinking about the GT-R logo and putting it where the V8 emblams are, i think i can get maybe a half horse outta each...What you guys think?? LOL

 

[Tunez]

Muffler in and out size should be 2 1/4.

As for the gains you will see or how much HP they add. No HP added but there is some freed up so you will get a difference. The sound is much more fun than the gain though!!

What are you talking about!?!? Those fart cans give the Honda Civics atleast 50hp!!!!! muhahaha. THe sad thing is 50hp isn't enough.

If you want to gain some horsepower, this is what you should do. Get the flowmaster 40's, 2.25" offset/offset design. GO to your muffler shop, and have them cut out the flexpipe, 3rd cat, and resonator. Have them find you a flex pipe that has the correct ID all the way through, because the stock one is tiny. Get the new flex pipe, weld up a straight pipe in place of all the crap you removed. Also, the exhaust gets tiny in the area of the 90 degree bends right before the mufflers, as it goes down to 1 7/8" to the mufflers. Those tips will give you slightly more HP, improve flow, and sound beautiful. Oh yeah, the 3rd cat is considered a muffler by ford, and you will still pass emissions.

Here is inexpensive way to gain ET(make it quicker) drop about 200 pounds of wieght on the car laughing

I have Summit Welded style mufflers and love the sound they make. The third muffler(Cat)will coming of this coming friday I hope, have friend who knows a friend. thumb

I got better 1/4 times by going back to the OEM sized tips vs 2.5".

My 3 & 1/2 year old is the same. She already has had her own road rage against another driver. I damn near crashed I laughed so hard at her yelling "you big poopie head" out the window at him.

Best thing about any of the performance muffs is the great sound of the small block V8. They will not add much to the performance but after they are installed just walk behind the car and listen. You will be a boy racer again.
