I was told by someone that an exaust full performance exaust system could actually lower your horsepower and same with in take is it true?

 

If you have too much air going into the engine, and not enough air going out...it will cause a lose in HP. I dont know about the exhaust causing a lose of HP though...Dont think or know what it would be true....

 

although big exhust systems in the 2.5" - 3" will give you a higher peak power, you will most likely lose power in lower rpms. its not that you will lose power, you will just make different amounts of power in different places, in other words: your power curve will change.

 

but do you think it will give better power in different ways iono is it best to get an exaust

 

the best way to find out what you can do is post a budget, we'll help you out with the best performance per dollar.

i'd say for the $600 you'd spend on a full exhaust, you're way better off to spend that on a P72 or P28 with crome or uberdata and a wideband. You'll seriously gain the most HP for the buck this way, and you'll know more about your engine and what really makes it go.

Once you are tuning your own crap the rest will come to you, you can, for example, take your exhaust off after the header, see that it makes you run lean, add fuel, get the same AF ratio as you had before, but with more air, more fuel, and more power.

tune it first, just adding boltons without tuning is like a blind guy building your engine, you have no idea whats going on other than the way it sounds.

 

Well i have an 88 prelude si so what would say do i wrecked my exaust and stuff so i think im gunno go with perfromance so ya

 

I would also like to get a performance exaust aroudn the price of like 200-300 if possible so i dont know

 

You can probably get a Megan Racing exhaust off eBay for that much. They give good performance for a decent price

for that price range, you will probably have to get a 2nd hand exhaust. you should look for a nice resonator, then get something like an es muffler, and have a shop make all the pipes. it will sound good and have the power you want.

es tuning muffler.............$110+s/h @ inlinefour.com
resonator........................$65+s/h @kteller.com
muffler shops usually charge $60/hour + materials ($100 total for mine)

so you're looking at around $300 for the exhaust.

 

okay, you have quite a range there, but for 200 i'd say buy a muffler somewhere, and have pipe bent back from the cat at some shop.

for 300 have the same thing, but get a better muffler, and a glasspack for $35 at autozone, thrush or whatever they carry.

Everything is about velocity of gasses. There is an optimal exhaust gas velocity to make power. If you have a bigger intake, header, and exhaust system, then with all else bring the same, you should make power in the higher rpm and lose low end power, as the velocity at lower rpm is slower than it was before.

 

so what ur saying exuast and intake and headers are mostly for show
