Both good options. I'd say they are about equal. TSP a tad cheaper plus they don't charge any extra for 2inch vs 1 7/8.

Just search this section for the brands you are considering. There are literally HUNDREDS of threads on headers and CAI's.

for giggles:


"Smaller diameter pipes flow less volume than larger ones, but the exhaust in the smaller pipe flows faster. Until you reach the RPM where the sheer volume of exhaust gases require bigger primary tube diameters, smaller tubes will scavenge the cylinders more efficiently. If you're using the engine in the 1,500 to 3,500 RPM range, which is typical for a street-driven vehicle, you definitely want 1-1/2" to 1-5/8" primary tubes for any small block and 1-3/4" to 1-7/8" for a big block engine. Any bigger and you'll lose a considerable amount of low end torque. beyond 3,500 RPM it is a question of where you want the power peaks. As you can see from the charts on this page, small tube headers do not lose their edge in horsepower and torque until you exceed 5,500 RPM."

also if your running headers into a stock exhaust system, you may not be doing much.

High performance mechanical camshaft, specs 250°/259° duration at 0.050 lift

First off its a big block old school with a weak azz compression ratio and it has measly 2.09 valves WE have 2.165 valves and a 1.60 exhaust and these Ls3 heads flow way more than those and these motors are more efficient.

Stop cutting and pasting with info you just read on the Internet.

Tha fuq? Man the gains had from cat backs are minimal if not non existing besides the weak sound and heavy cans ls3 exhausts are extremely free flowing! Just an fyi

I think he is referring to the always relevant carbureted big blocks from back in the day.

is there any data like this that is relevant to our mordern engines? i feel that that info was not at all releavant to modern engines but i did learn something from it. I now want to know if the the results for the shorty vs long and various primary sizes when compared to each other over the whole rpm band vice just peak numbers that get thrown around so much

1) What brand of air intake and I want to keep my washer bottle in place. I read the air intake thread, but the runs didn't seem consistent or were on different test cars so I discounted the information.

2) throttle body and manifold.

3) What type of headers. I see stainless steel power (SSP) and stainless steel work. What's the difference? If the SSP rust out in two years, I don't want them, but they are priced cheap, but why?

I guess im asking you to list what three performance modifications you bought in or under the $500 range.
FYI, its just Stainless Power, not stainless steel power, also you said will the stainless rust out in two years, stainless steel doesnt rust.

They are a quality set, made by Stainless Works, a quality company.


Intake wise, get a CAI, Inc. (cold air inductions brand).

But seriously, search.

Lol someone needs to freshen up the modern era engines a bit more lol now @ right to travel to this date the stepped kooks headers were yhe best on the market since they will go from 1 3/4 to 1 7/8 allowing the air to compress and rush in at the beginning and then expanding and allowing more air to come by and get released out the back so you get the low end from the 1 3\4 with the top end of the 1 7/8. Now these new tri y headers are suppose to be the next big thing for around the same price as the competition so ill save my pennies for those just my .02.
