So I bought pacesetter headers with cats that turned out to be magnaflow and a slp y pipe for $260. I plan on getting them on before winter or in the spring. I am also going to most likely get the bbk intake manifold. Mattering on cost I would like to get the car dynoed before the manifold. Then I will get the car tuned. For the price I paid I know I can get my money back if the numbers don't work out. I have base line numbers of 326hp 326 tq on a 2000 ss with 45,xxx miles.

A little bit more clarity might help a tad here OP

They are pacesetter shorties but I'm going to get hp numbers after they are on. Everyone hates on shorties and some think they are not bad. So I would like to see what the gains will be since you never see any numbers, I'm hoping for 10-15hp tops.

i wouldnt count on gaining that much if its a bolt on motor.

I agree that with just bolt ons that it won't make much difference over a good shorty header...at least not enough to warrant the hassle and expense

So you are saying that I will not get 10-15 hp from the pacesetter shorties and slp y-pipe? I have a slp lid, potz tb, lm2 and that got me my 326hp. The car will be a bolt on car only.

Do you plan on doing the same dyno...before and after? Otherwise you simply won't know how much you've gained

id say more like 5-7. not enough to notice and imo not worth it.

Yup same dyno baseline of 326hp at slow hawk with lid, potz tb, and lm2. Does anyone have numbers that prove 5-7, I have seen dyno charts with corvettes getting 7-8hp and there manifolds are better, so why would I not get more?

good discussion. yes,its on ls3s but ls1s are referenced.


its your car but most will say go with LTs or spend your money elsewhere.

I will try to find a page I found it was on a 04 gto that got around 15hp from shorties with a dyno chart. It was old do it going to take me some time. I will also like to find that corvette one too. I just thought for $260 I couldn't go wrong. They have pacesetters have the carb plate so if the do nothing on the dyno I'll sell them and the cats have to be worth something.
