na engine with 3" exhaust?
 

would a 3" exhaust increase or decrease the performance of my car? or will it just change around where i have the power? like more top end speed or more low end torqe?

I'm not to sure but I think it would definatley ruin alot of your low end power and burn up your seals.

What seals would it burn up? It just a exhaust i can see how it would mess with the power but seals?

I could be wrong about the seals thing, it just could be a myth a heard. I do know that its not good to run the car without enough back pressure.

it wont kill any power, it will be all performance. im almost 100% sure that the exhaust will only give u positive results. and theres no seals to brun either

I have been told i will lose low end power cause of the increased exhaust, i mean they put 3" on turbos cause they have more back pressure which means they need a more open exhaust, i wish there were dyno test results or somthing lol if i get mine down i will dyno it before the exhaust and then after see what the results are

this might help http

2.5" is probably the biggest you can go on an n/a to get good results. 3" is way too free-flowing, and yes youll lose low end torque. check out the "Exhaust systems researched" thread in the FAQ.

i agree with him
n/a with a 3" exhaust and youll lose sum bottom end power
ie sum torque
n/a uses the backpressure of the exhaust system to gather up sum torque
have the exhaust too free flowing and loss of hp will occur
idk about top end power
well there's not really that much with the n/a
cuz its starts to slow down at 4th gear

The only possible damage it could do is (this is rare), when the outside tempeture is cold-- really cold-- the exaust pipe will build condensation. This can travel to your exaust valves. Then when you start the car ---WARP!

But a friend of mine has an N/A with three inch straight pipe and he loves it.
I would not worry about the bottem end power.

Also if you need back pressure and a bend at the end of the pipe when installing.
