Is there a need to upgrade when i do a header, supercharger and other performance mods?

 

only if u want more power. whats the point in doing a s/c and stuff if ur not gonna get the maximum power out of it.

 

yeah...our exhaust..i wouldn't say is good for power...stock form yeah...sounds good yeah...but power wise...your not gonna get alot out..let's say you got a S/C with stock exhaust...might as well upgrade it to get more power out of it.

 

Very restrictive compared to my Greddy.

 

on dyno's the OEM exhaust/header combo performed extremely well

 

do u have vid or dyno sheet of the performance?? also what type of header was it?? thats shocking that the car performed well with just a stock exhaust and a header.

 

if youre going to boost you will need a bigger exhaust, if you go NA the stock one will actually do about as well as any aftermarkets.

 

From the factory the new 2006 Honda Civic Si boasts some impressive numbers. Normally aspirated the new Civic Si produces 171hp and 126 lbs of torque (as measured on a Mustang Dyno).

However, boost is KING! Doing what we do best, we set out many months ago to create the finest supercharger system available for the new Civic Si. Our newest addition to the JR family represents our best work. How did we do? Horsepower on the base kit increased to 234hp and 171 ft. lbs. of torque (measured at the wheels on a Mustang Dyno). This is using the stock airbox, header and exhaust. Not CARB approved.

That is what the Jackson site says. I feel that is impressive for all stock componets.

 

Seems kinda weak considering comptech did pretty well and maintained CARB approval.

and the stock is probably a lot quieter than a loud *** after market exhaust. Some people dont want a loud car 24/7. i prefer quiet except when i get on it.

What the hell does this have to do with the posters question on exhaust? Or were you just looking for an in to do some free advertising?

I only felt that was aiding in the question because those are suppose to be numbers with stock componets.I do believe he is asking if he NEEDS to upgrade. I thought they were good numbers for stock exhaust!

 

If it was as good as it sounds, it would be fantastic. sadly, that's far from true.

IF i had the money, I'd definately upgrade in order Intake, Header, Exhaust.
