hi, what are if there is any the negitive effects of using a de-cat pipe rather than a high flow cat? I know it will fail the emissions test but I can get round that. Is there Much of a diff in BHP? was gonna install a megan de-cat on my 1.6 vtec as figh flow cats cost a lot over here.

 

you will gain a little more horsepower higher in the powerband but loose some torque. it also give you that loud piercing sound....kinda like running open header, but a little lower.

 

go with de-cat if you can

 

Thanks lads!

 

you wont lose torqu, if any thing you'll gain it.

 

u do loose a little torque

 

and your car stinks, and police hassle you, let alone the fact that you are doing more damage to the ozone than a catted V-8.

 

watta hell, I thought any back pressure was bad, sacicons isn't that what you preached?!

 

would the car be any louder....

 

bro loud isnt always good..........god damned ricers!
