"A stock 2000 2.7 should put around 180 to 185 hp on a mustang dyno so I gained 25-30 hp with those 3 upgrades that cost around $1600.00"
I am glad that you had that much of a performance bump with just intake and exhaust mods, especially for the money, thats great. I have read about others, expecially with 3.2L cars, that have had good results increasing hp with exhaust mods alone.
I am not sure what its worth, because many of the companies that sell mods make unrealistic claims about increased HP with their products. But at the TTP website they say you should expect about a 25 hp bump when you do their exhaust, intake and chip for a 2.7L engine. So my numbers seem pretty much inline with what they are reporting. I think the last run I did on a Dynojet dyno was 204 hp to the wheels.
Because I did not do the exhaust system until after I did the chip and intake, all I can say is that the exhaust added another 5hp or so, I dont know how much it would have added before adding the intake and chip. The shop that did the install also said that in most cases with a 2.7L engine, you could expect a 3-5 hp bump with headers and cat-back exhaust.
