View Full Version : Emissions cat

12-06-2005, 05:29 AM
So, my car is getting close to being done and is getting a custom exhaust. 3 inch back. slip in/out cat converter. I've been trying to find a decent one for a decent price as I will only use it for emissions.


would something like this be overkill? magnaflow's site is confusing. I just want something to keep the air healthy, but be cheap, and something that can go in and the come out.

Looks good, only issue is that it's designed to be welded into place -- you'd have to add flanges to make it removable.

Not that I understand the purpose of removing your cat, unless you've already removed your trunk carpeting. The two have about the same effect on performance.

Well. What's the purpose of the turbo guys gutting their cats then? I've always understood it as being a block in the exhaust system.

As far as removing things. I'll be stripping this one, yes.

I gutted my cats because they were clogged and causing performance issues.

Then I welded a high flow in where the secondary one was and left my primary gutted and I didnt notice a difference in performance, just a little bit of sound.

If your turbo spools just fine, with it on, Id leave it on. If you want to build flanges for it though, run a test pipe.
