Straight Through Pipe

[Hulk1010]

Does having a straight through pipe make much of a power difference

also would i need to get the pfc settings adjusted in anyway if i was to get a straight through pipe?

thanks

straight through pipe on what.....and where.....

instead of the hiflow cat

No powerFC adjustment necessary. On a mild car the difference would be 2 tenths of f**k all. On a heavily modified car it may make a difference.

so i would be wasting my money?

Yes it will be a waste of time and money.

And you'll also cop a massive fine from the EPA if they catch you. And by massive, i mean massive.

last i heard it was about $8000, but i could be wrong.

The only difference I noticed was the massive flames out the rear muffler on gear changes, no power difference from the drivers seat though.

If you do notice a difference you have the wrong Cat installed.

Just to test the difference a cat makes, I used a straight through pipe from a friend for a few hours.

Compared to the stock compliance cat, it made noticeable difference. If I can feel it, i'm assuming the difference is about 5-10kw.

There was also flaming and popping, which was fun.

But I'm not willing to risk a massive fine. I got a stainless mesh cat, and it feels the same as the straight pipe.

Obviously it will still be more restrictive than straight pipe, but it isn't noticeable, so maybe 1-2kw difference.

oh... If you do like the flaming and popping, my car is running ultra rich in its untuned state, and I have got it to flame through the stainless cat.

If you can notice it, its more than 5kw.

If someone can notice 5kw on the street i'll give them a medal. Its esentially impossible

[Bobjones]

I have seen 10awkw or more on a Evo VIII replacing the highflow with a straight through pipe...we are talking one with a few mods (ie 220awkw) and yes you can feel the distance...and the MPH shows it also...

Oh and that is NO tuning, WITH tuning there was even more...

But on the street...having a straight through is like asking to be the sphincter of the universeed on BB....

running no cat can result up to a $33000 fine in court for an individual or $250000 for a dealer.
