Test pipe, do they really do you any good?

[tekung89]

i've heard many stories regarding test pipes.

some say u lose torque because there is not enough back pressure and the car drives like shiet, but however u gain top end. others reckon it doesnt benefit NA cars at all, only boosted cars.

anyone wanna throw in their 2cents and post some dyno sheets =]

The only benefit is a lighter wallet when the EPA fines you $10,000 for not running a cat. Go for a high flow cat instead.

if it didnt give u more power why would ppl take their cats out n put the test pipes in?

[JasonGilholme]

cause they're too cheap to buy a high flow cat

It would really come down to the build set-up wouldn't it?

coz putting a test pipe make u a rebel and give u 2 more whp only ur engine is quite highly modded.. putting a test pipe without engine mods is prob 0.5whp..

only good for track

That makes sense

[tekung89]

only good if u want you future kids to be poisioned with polluted air

umm har har? im asking if there is any benefits to a test pipe, not wat it does to the environment. and obviously track use only

straight through pipe --- more power

You are better off using a straight through exhaust with no muffler and no resonators with a cat, then if you used an exhaust with mufflers but no cat.
