Default Can you DIY Install a full Cat-back system?

Hi All

Quick question: Can you install a cat-back system (say a Greddy type) by yourself, ie. no welding or specialised equipment needed?

Thanks in advance

If there is such a thing, then yeah I guess I am. I'm just under the assumption that the system would need some form of welding?

You don't need to weld anything, you just might have to heat up the bolts because if they have been on there for a while then they might not want to come off. If you get a Greddy exhaust I think that they will come with the gaskets and new bolts to replace your old ones because it is likely that you will break your old bolts because of how hard it can be to take them off.

Oh yea and for your sig, put "[img](link here)[/img]" and it will show up there without needing to click the link.

I've said it before, you're a legend man. Thanks for the reply.

I have a follow on question though. My car is almost entirely stock, the first thing I'm doing is a chucking in a SIR (thanks for that) and following that, probably new headers, manifold and cat-back.

That being said, what would you suggest I do first? I want a performance gain, but also would like it to sound a little bit more like a tuned car and little less like my grandmothers run-about. [&:] Can I install a custom cat-back onto stock headers? (I'm thinking thats what they attach to right?)

Is a full cat-back system worth it, or would a custom muffler suffice?

np, I like helping ppl when I can.

probably just an accident but just so you know if it wasn't an accident, the headers replace your manifold so you don't get both.

what would you suggest I do first? I want a performance gain, but also would like it to sound a little bit more like a tuned car
You will get the most sound out of a catback but I would start with the intake and it will give you a little better sound also just not as much as an exhaust would.

Can I install a custom cat-back onto stock headers?
Yes

Is a full cat-back system worth it, or would a custom muffler suffice?
Custom would suffice and is probably cheaper but that is usually the choice if you want to turbo your car and need a bigger exhaust piping size. Then you have to get a resignator, muffler, and cat-converter then go to a shop and have them put it together for you. So I suggest that you just buy a catback system if you don't want to mess with all of that.

ORIGINAL: Mr Mobsta Man

Thats what I originally thought, but saw this and it threw me.

Intake Manifold

http://www.modacar.com/products/Hond...manifolds.html

Headers

http://www.modacar.com/products/Honda/Civic/MODAHEA/

The Intake Manifolds listed here seem to be the part that sits on the back of the engine, where my injectors and fuel rail sit on (where the intake piping would come out of).

Is this something you'd normaly upgrade (performance wise), or an I getting my wires crossed?

What you have labeled as Intake Manifold is actually for a turbo application. Turbos use the force of the exhaust to spin a turbine that foces air into the engine, hence the name intake manfold. The headers are actually the exhuast manfold, and sit on the front of your engine. They take the exhuast into one pipe, which then goes through the catalytic convertor (cat) and out to a resonator and muffler. A catback system replaces everything behind your cat, and won't bolt directly onto the headers themselves.

Installation of the catback is fairly straightforward....its more of getting the old bolts out that will probabaly give you the most trouble. After you get the old out, its simply a matter of sliding one tube into another, securing clamps, and pushing brackets into rubber hangers. Its not the easiest thing in the world, but with a little time and patience you should be able to do it.

In my opinion, go for the intake first for sure. It'll probabaly give you the most noticable gains in performance...from there, go to the exhuast, and exhuast manifold (headers),

Ok I thought u meant an exhaust manifold. Yes you can replace your intake manifold with an aftermarket one for a few more hp. I think that the Skunk 2 intake manifold is a good one from what I have heard. I still have a stock one.
