I am getting custom built pipping and i am wondering should i get 2.25 inch, or 2.5??? thank u...

 

2.5 if you plan to be serious about an N/A build up.

 

depends on what else you plan on doing to your car. If you can afford it go with the 2.5 just in case you decide to do N/A work down the line.

 

This is gonna be a N/A car, ill be getting headers, ignition, AEM Fuel rail, AEM fuel pressure reg., stuff like that.. thank u

 

anyone else??

 

2.5

 

2.5 all the way!!

 

i agree with everyone else 2.5" for all motor
2.25" for bolt-ons (intake, header, exhaust)
make sure you get mandrel bent piping though so it has the same diameter through all the bends

 

so if im not gonna do no turbo or supercharger, i should get 2.25? because all im doing is like headers, exhaust, ignition, stuff like that???

Exactly.

 

unless you plan on building the bottom end w/ higher compression pistions i'd go w/ 2.25.

 

In the long run you want to get the 2.5in piping all the way through your exhaust system, that includes the collector on your headers, that catalytic converter, and cat-back.even without forced induction youre going to see much beter HP gains throughout the RPM spectrum with better exhaust flow...2.25 is really more like stock power, you wouldnt see any REAL gains unless you were going full throttle. keep in mind though this is assuming that you also have an intake and some internals done like port/polish, cams, adv timing, maybe some high compression pistons.

 

so if i dont have aftermarket cams and internals i should not get 2.5???

Correct. If you plan to stick with basic bolt ons (make less than 175 whp), a 2.25" or 2-3/8" exhaust is good enough.

 

so what if i am going 2 rebuild my engine with high compression pistons in about 6 months, should i get 2.5 inch pipe???

 

you got to think of your engine as being made of parts that make up the whole...no one part is going to make a big difference, its the combination of different parts working together that make the power. if you were to JUST get high compresion pistons you would still have to get cams because of the modified air/fuel mix and tuning to get the most potential... and like i said earlier, if you are going to do engine work in the long run, 2.5in piping is the best way to go if you go N/A...it just depends on what you think the final goal is for youre ride.

 

well i know, im just sayin, im rebuilding in about 6 months and im gettin cams, crank, pistons, stuff like that, so yall r saying i should get 2.5

 

Yes, if you plan to build up the engine in the future, I would say go with at least 2.5" ID exhaust.
