Hey guys,

My Header-Tech header will be arriving today and I will be installing it sometime this weekend.
I will be receiving the 3"-2.5" reducer along with it so I can match it up with the rest of my exhaust piping.
From what I"ve read this will <U>not</U> be a direct bolt on so my question is would it be better to install a test-pipe/flex pipe or even a resonator between the end of the header and the start of the exhaust?
I would like to have the car a bit quiter than it is now but I don't want to sacrifice much in terms of power loss. Will a high-flow resonator do the trick?

Can someone lend me some advise please, it would be greatly appreciated.

Thanks in advance.

Nate

I used flex pipe, but it really isn`t a street car. I don`t run a cat.

 

I don't have to run a cat since we don't have inspections here in Canada but I am just trying to keep the car as streetable as possible.
It is a daily driver and I am trying to keet the noise to a reasonable level?

Does a flex-pipe reduce back pressure as it is not a solid piece of metal?
Anybody have any comments about simply installing another high flow resonator?

 

Anybody with a suggestion or recomendation??

 

Some resonators will hurt flow others won't. They aren't all the same.

If the collector doesn't incorporate a flex joint then you better use the flex tube or you will crack something in time.

 

Thanks Dave. I'll go ahead and install a flex pipe then.
If it gets too loud I'll consider adding a resonator later on.
