So im looking to get a new Downpipe header and high flow cat. I got a catback exhaust right now but im in need of the rest to make it complete.

Whats the best place to get the stuff from? Do i need a high flow cat? I might sound stupid but I was told a Test pipe goes in spot of the Cat and you just mount the cat when you go to emmissions? is this true?


Let me know some price ranges too if you can. Thanks for the help. BTW Search doesnt give all the answers i need.

i got an 05 2.0 ss/sc

 

There are many vendors that make headers and down pipes for our cars. Check out the vendors section.

It also depends on how much you money you wanna throw at your car. I've heard a lot of great things about Clear Image craftsmanship, but they cost a pretty penny. Pacesetter makes a decent header, but costs less, and no down pipe.

If you get a custom down pipe, with the test pipe welded with flanges on either end, then get a cat with the flanges in the same spot, and interchange them as you wish, I think that's the only route for you to do that. A true down pipe with high flow cat is just that, a nice pipe with a superior cat welded in it.

I would expect to pay along the lines of $400 for a good header/downpipe with hi-flo cat.

Hope that helped.

Get one from Imortal Technique

Then you're exhaust will be hot hot hot.

The only thing you can buy for around 400 bucks catted would be from zzp I'd imagine.
