when it comes to the dual exhaust which would be better two 2.25in pipes all the way back with mufflers and cats. or one 3in all the way???

also what about the intake? which would be better two or just one?

ive heard good and bad fro both sides. what do you guys prefer or hae on and how much did it cost??? also waas the performance gain noticeable?

 

Read this thread regarding 1 verses 2 pipes into the throttle body...

Also, see TVT & Needswings air intake designs.

 

thanks man. i appreciate it.

 

ok but theres one issue with the url you sent me. there is no dyno sheet or proof of which is better. also the exhaust too.

 

Cross Sectional Area for a 2.5" pipe is 4.91 X 2 pipes = 9.82"
Cross Sectional Area for a 3" pipe is 7.07"
Cross Sectional Area for a 4" pipe is 12.57"

All of the above will flow more then enough for these 3.2L motors.

Dual exhaust is about pulse balancing and sound.

There are countless 500RWHP Supras and Camaros running a single 3" exhaust and the same amount running dual exhaust (no supra on that one).

For a street car it's a personal preference. For a race car it really depends on what your building it for.
