Other than legnth, what is the difference between long tube and short tube headers?

Is there a performance or sound difference? Is one style more preferable over the other?

shorties are for cali people and won't make more than 5hp gain
LT's can put down 20-35rwhp depending on FI,nitrous,cam
a cam should be done w/LT's to get the most HP gain, it's common to see 70+ rwhp gain w/ cam/LT's
LT's make more noise and sound awesome

I gained 85rwhp with Long Tubes, cam, Blackwing. Check out my vid (see sig) for the sweet, sweet long tube music

Long tubes =

Short tubes =

looks like LT's hands down so far - anyone else? anyone real happy w/ their ST's?

Also, what's the difference b/w 1 7/8" and 1 3/4" sizes (other than obviously 1/8") - ie: what is the sound / performance difference between these sizes and when do you use each? I assume it has something to do w/ needing more exhaust flow for more aggressive mods?

All depends how far do you want to go with the car?You can't beat short tubes for the easy install,and I have seen some fast #s on them.My buddy Ted(flatlne) ran them on a stock motor with an ATI charger and was 11s flat.There is a Z06 that runs the same setup as flatlne at Cecil with stock motor on nos 10.7s.

Long tube headers produce a scavenging effect at the upper RPM ranges on N/A engines. The lenght of the tube determines the RPM range that the effect takes place. This is known as exhaust tuning. Obviously, the shorter the header the the lower the RPM range. Consequently, shorties don't produce much more HP than the stock headers. Pipe diameter, also effects tuning and the scavenging effect. Too large a diameter for the cubic inch displacement of a N/A engine reduces the effect. Adding Forced Induction to the engine creates a different senario and some Tuners don't recomend LTs

...And some other states too, like Nevada. Actually Federal Law prohibits the removal or relocation of OEM cats. LTs are technically illegal in all states and the smog ***** can fail you IF they choose. You are off the hook if you have no EPA smog program since they don't inspect.

Good 'Ole North Dakota - it's cold, but no smog *****!!

I am very happy with my Shortys, I made a gain of 10 rwhp. LTs must be removed when changing a clutch.

I've been happy with my B&B shorties also. I knew LTs would be better but here are the numbers I was looking at:

Shorties -
$200 used (stainless steel so they are as good as new)
$0 labor to install (I did it myself with regular tools in about 4 hrs).
I can return back to stock easily.
Option to get my money back out of them in the future when I get more money and want to do LTs.
No need for tune after
~ 12 rwhp

LTs -
$600-$1500 depending on brand and condition.
$300 to install (this is a guess... you get the idea).
Must modify the rest of the exhaust (hard to return to stock).
I think some people recomend a tune after ($400)
~20-35 rwhp

Since I only had a few houndred dollars to spend, I couldn't say no to such a cheap gain in sound, performance, and maybe looks. Its funny how people will say shorties are horrible when I paid $200 for 10-12 hp but they will tell you a $250 air intake which gets similar gains is the best bank for the buck. Plus you could gain ~7 hp with a free zip tie mod so really the air intake is only a 5 hp gain over "stock". However, I do agree that it is not a good idea to buy shorties new at msrp.
