what's the size of the stock exhaust piping on a 92

 

at a guess...
isn't it like 2"??

 

I wanna say the 1.9" inner diameter..

 

Hehe, my knowledge is needed!

My '92 Si has 1 7/8" piping stock

 

if I went to 2.25 or even 2.5 and put on a nice muffler would I lose or gain....I know too much and you lose...

 

That depends on what you are doing to the motor. Throw a turbo, SC, or nitrous on there and a 3" will be beneficial.

 

3" is a bit big for nitrous; you want the best performance off the bottle, since that's when you drive the most (unless you're a madman!). Is 3" good for S/C? Cause I know they still need backpressure, unlike a turbo. 2.25" is a good accepted size for a N/A car.

i'm probably going to go n/a for a while...maybe a header...no money....just want something cheap and easy.....what I REALLY wanted to do is do headers then 2.25 cat back split into dual exhaust. practical?? i'm probably going to do autocross but still want some style

 

I dont recommend going for a dual exhaust setup. And 2.5in piping will probly get you the most hp with a small loss of torque.

 

just to be curious......what's wrong with a dual setup????

 

should I get full exhaust system from say....greddy?? or should I get custom piping from a shop??? Personally I like the look of some of the universal exhausts such as obx, but I'm not sure if there up to par with name brand equipment.

 

If you want performance, buy a catback from a bigger company, like Tanabe or Greddy or Thermal. Just a muffler won't do anything but change the sound. Most shops use crush-bending to make the pipes fit, causing a lot of turbulence and restricting in the bends, so unless you know of a cheap local shop that does mandrel bending, go w/ a full catback.

 

how much of a price difference are we looking at?? not an exact cost but general estimate??

 

You can get a Greddy Sp for $430

 

What's the best functional hood scoop one can get.....I kinda like the ones on old school mustangs.....so what is there???
