I was thinking Of adding a Downpipe and a Test pipe But leave Stock Catback... Can i do that? Will i get any power? I want to Leave Stock Catback soo My Car will look stock... Im Not saying Im going to Leave Stock Catback the Hole Time... But After I run Someone Then im going to Change the Cat.

 

It all depends on what size DP and TP you get. If you get a 3" set up then i will help the spool up a little bit but you have to remember your exhaust is only good as the smallest diameter.

 

*edit*
nevermind i didnt read right! Im sure the test pipe and downpipe will help out, but you still neck down into the smaller diameter stock catback system, theres probably something in maybe a 2.5" thats compatible with the stocker.

 

What he means in run a DP,TP and then follow it up with the catback exhaust, which doesnt include the actual cat.

 

It's recommended to start at the back of the car and move to the front with exhaust components, however you'll definitely gain some power by replacing the stock cat.

 

It would just be a waste of money. I recommend spending that money on fixing your CAPS LOCK key.

 

Adding an axel back would do a bit in freeing up some hp. The stock muffler is pretty restrictive..

 

+1. just do the tp if your not doing the full thing.

 

here you go again with your stupid wise *** joke.

 

Dont waste your money on just an axleback. If you want to keep it simple at least pick up a catback.

 

Get a megan racing turboback with test pipe for around 550 bucks. Leave the silencer plug in and your car will sound pretty quiet and it will be faster. It will be less conspicuous and unilkely to annoy the police. Then take out the plug (2 screws) when ya wanna go fast and make some noise.

 

You'll see some gains just by replacing the cat with a test pipe. Not sure if a downpipe in conjunction with a test pipe and stock catback would be worth it though. I still have my stock downpipe and stock catback and saw some gains just by replacing the cat with a test pipe. Stock catback is still restrictive too...

 

Warrtalon Grow up...

And Im Going To add the Full Ams Turbo Back.... But Im going to race a Redneck Who always Bashes on my Evo So i want my Car Too look as stock When i do.

 

i kinda thought the caps lock joke was funny.

cmon guys, its all in good humor.. most of the time. Just dont get a big flashy burnt titanium tip and it should look pretty stock.

 

The Ams TBE Dosnt look Close to Stock... And this Guy Knows Evos.. His been Studying them.. Since i got mine.. He always trys to bring it down and bash on it.... Mustangs this days.
