I'm thinking to downpipe my evo x but I don't know which option I should go with Greddy or AMS downpipe. I have Greddy Evo3 exhaust sytem and AEM cold air intake right now. Which downpipe should I get?
My cousin told me that downpipe is a downpipe, there is no different which downpipe I get. He builds a lot of cars and he suggested me to go with Greddy.
Note: My car have 7k miles on it right now. I'm waiting for it to reach 3rd oil change then I will downpipe.

 

I'm sure most people would recommend the AMS but Im thinking of getting one too and I'm looking at the Tomei DP just because it looks like it easier to install.

 

If you want to stay greddy then go with that. AMS or ETS would give you better gains.

 

Is there a greddy down pipe like ams? Only greddy downpipe I have seen are the short one and not a full downpipe.

 

downpipe is a downpipe.

 

You want to be careful which downpipe you choose. Some are literally just the downpipe and others are the o2 and downpipe together. If you get just the downpipe, it will not be beneficial.

Take a look at our exhaust components for the X.

We have some of the highest performance gains in the industry.

Thanks!

Can't go wrong with AMS. I've been rocking mine for the last year and a half without a single issue.

 

I always read that "a downpipe is a downpipe." After doing a bunch of research, it just simpyl isn't true. As Michael said, an o2 downpipe is going to be a whole lot more beneficial.

Of course, unless you're planning to upgrade your turbo, you don't really need a downpipe.

You don't specify below, do you have a test pipe? Is that part of the exhaust system you referred to? I'm not very familiar with the Evo 3 system. That being said, a test pipe would be more worth your money than a downpipe, until you upgrade your turbo.

 

I'm also planning to get a high-flow cat to go with the downpipe

 

We have a really nice HFC as well on our site.

which downpipe would you recommend if I do go with ETS

 

I really like the recirculated downpipe. I'm not big on all the extra noise associated with the dump version, but that could just be me getting older

I have had ams on mine for quite some time. It is a great piece. Taking it off soon though
