well iv been pulled over many a times in NJ and never had an issue with a cop asking me if i have a test pipe or a cat on my car. iv been questioned about my exaust a lot but they just say ok and let you be on your way


and about the smell no difference then haveing a cat on the car. iv been behind BlackevoVii a lot and never smelt any thing..

 

Yeah but when you answered did you say, "Cat" or "testpipe?"

Because if you said cat, then you just didn't get caught.

 

280

 

Alright, I changed the exhaust to a full Megan turbo-back with a high-flow cat. Feel free to change your guesses.

Changed the exhaust...

Megan Downpipe
Megan High-flow cat
Helix Cat-back

 

282

maybe we should start a pool... 5 bucks?

 

Lol, yeah...EVERYBODY can Paypal ME $5 and I'll pay the winner! :P, promise i won't cheat!!!!!!

 

LOL then you could probably put down 400hp =D

 

i HIGHLY doubt by just taking out the stock cat and putting in a high flow/ test pipe u get 20hp from the cat alone. sounds unrealistic to me

 

me too, but hey if it does....awesome!

 

Believe it, buddy. Turbo's hate any kind of restriction, especially in the exhaust. Have you ever seen the inside of a stock cat? When you put on a turbo-back exhaust, most of the power comes from the test pipe and the cat-back/axle back.

 

I just put on a testpipe and even though my car isn't dyno'd, you can definitely feel a significant increase. Just as much gain if not more than when I installed my cat-back.

 

im not saying you dont feel n e thing, i know that you do, but u not 20hp, MAYBE 20 crank. not tryin to be a dink tho

 

What about the high flow cat, is it kinda in between a stock cat and a test pipe or is it the same thing as a test pipe hp number wise?? Not sure, need some opinion!
