NEW, Need advice on upgrades

[dsm25psi]

I just got my evo been saving up for a while for this car. I got 2005 evo8 and I love it.
I need some advice on the upgrades where should i start and with what? Another thing is about exhaust what exhaust can i get thats not to loud? Can i do 3" downpipe and no cat but keep the stock exhaust? I been ready a little about the dynoflash and i heard some guys say that with only dynoflash on stock evo you can get up to 40hp is that true?
Thanks

Welcome, and great choice on the Evo.

Do be sure to search around and learn some things first, though. We're definitely here to help, but it also helps if you do some work on your own and read all the great advice we've already given to others with the same questions.

Here is a thread showing a package I created that includes what I consider to the basic stg1 mods that any Evo should have - in your case an Evo VIII (different mods from IXs):

You by no means have to get those exact mods, but that combination of mod types is what you want to look at doing. I can't help you much with keeping the exhaust quiet. Yes, you can do a test pipe and DP connected to the stock cat. That's backwards and won't net a lot of power, but it will definitely be much quieter than doing a full exhaust or even just a cat-back.

Here's a little something too;

As far as quiet exhausts; a while back Turbo Magazine tested a few (March '06). The stocker tested 92dB at idle and at 3000 RPM's. The one that caught my attention was the Turbo XS; made good power, not the most, but tested 94dB at idle and 98dB at 3000 RPM's. All others were louder.
An exhaust with one ore two resonators is going to be quieter then an exhaust with none, but it will be heavier too. Also make sure those resonators are a consistant diameter to the rest of the piping with a straight through perferated core for best flow.

Thanks for all your help,
Do you have the picture of the turbo xs exhaust? or the name of it,
thanks

From their website they only had an exhaust pic with the DP and TP in it;

PS
Don't get confused with XS Engineering (a whole different company) or XS Power (Chinese stuff).

I tried finding the article on Turbo Magazine's site ... couldn't find it. Does anyone has a link to it, or a copy of the article? Thanks.

I've searched their web site, but I couldn't find it. I just have a copy of the issue. When I get back from camping I can post the results from the other exhausts.

Hey, ADX, thanks for that, but I'm pretty sure the HKS Carbon Ti weight is wrong.

Welcome. Allot of people make foolish mistakes modifying their Evos, and by seeking information you have taken the first step toward not being one of them. They are great cars stock, so be sure that every mod you do is actually an improvement you will use. However even just a few simple and well chosen mods can produce great improvements.
Yes, freeing up the exhaust and ECU tuning are excellent places to start!
