Long tubes and some hi-flow mini cats might pass sniffer, but if you have visual your screwed.

And I think the better name for a pro chamber would be "pro chamber exhaust crossover" as its not an H pipe.

ok but if you look in any catalog its listed as an h pipe, even on the mac website. but lets get back on topic, lt are more hp than st. by how much with full exhaust done?

Pro chamber has its own section. You can stop trying

Anyway:
Shorties are going to give you almost 0 gain, Long tubes will give you a 5-8hp ish gain.

[6banger96]

5-8? thats it? it dont seem worth it for the money

[whitemustang02]

hp costs mony
and what for that mony do u think will get u more power

Every mod under 300$ is going to give you around that hp....
Letting your engine breathe better is your benefit from long tubes, or you can keep the stockers. Your going to pay 250$ for a pro chamber + the money to have it fabbed up right?

the people at mac said it will mount right up to my headers and flow tubes that i got. what would have to be fabbed?

What are "flow tubes" ?

[6banger96]

to connect the muffler to the h pipe because i originaly got a cat back the bolts to the stock y pipe, and they said i would need flow tubes off the 96-98 gt for the prochamber to fit my car

Maybe so, but still you dont see how 300$ for long tubes is worth it...
The 250$ for a prochamber is gonna net you 1-2hp maybe....
or you may not gain anything from it.

[6banger96]

no i just thot it would be a little more hp than that for an exhaust upgrade thats all

Aha,
Well your probably still going to need some fab work to connect the pro chamber to the headers. From the outlet to the mufflers should be easy.

However I would take that 250$ add a few more and buy an xcal

[6banger96]

im sorry whats an xcal?

o. but do you have to have all your upgrades done first for them to program it or do you program it your self as you go? im sory i dont know alot about tuners as you can tell

You can adjust some things yourself....

I'm pretty sure you get 3 tunes with that so you can have 3 different setups now, and you can always get different tunes from VMP. Plus if you ever go to get your car dynoed you already have the tuner. Much better investment than a pro chamber.

[6banger96]

ill probly get both. i would like to get like 250hp out my car n/a.

Long tube headers
Exhaust (some catback, magnaflow would be better for power)
* You don't need a mid pipe (h/x/pro)
UDP
CAI
Split Port Swap
H/C/I
Rockers
Nice Tune


That MAY get you to 250rwhp....

i dont understand how i wouldnt need a midpipe if i get long tube headers. and how is the mac cat back on power since that is what i have now?

Because you don't need one? I ran straight pipes forever (no mid pipe back to the mufflers a.k.a divorced duals)... I don't understand why you think you do need one.

Its just like the rest of the chambered mufflers... It doesn't flow very well
