Default What kind of exhaust system is this?

So I found this on yard sale and got it for $10, they said it would fit a 2004 wrx so i bought it. Is it catless? or is it straightpipe? what kind is it? (I know its magnaflow). Sorry i've never owned a sports car until now and I am barely learning the ropes about mods. Also would u recommend I install this without doing a tune?

It's a catless downpipe with a more or less straight pipe(no resonator) with a muffler on the end of the exhaust. If you choose to install the downpipe especially and the catback section, yes you will need a tune.

depending on the tune the downpipe will give you about 20ish+ hp than stock. you definately need a tune to run the catless downpipe thoughh because your engine will not like you haha

Sweet, awesome, 20hp is more than I expected, but that is great!

As for the tune, lets say I install this thing, should I get it towed to the tune shop or would driving it for a short while be ok?

you should refrain from driving it as it will set off your engine codes and mess things up. but you can put the catback on and take it to a shop and have them put on the downpipe when you get there and have them tune it.

just saying. catless smells like gas all the time and you could get in trouble with the 5-0.

but damn $10 ?!?! that's crazy!! check all the welds and make sure its not all messed up though

lesson 1. Don't buy from a yard sale where you dont know what it is
lesson 2. +20hp ? Idk about that but you'll NEED a tune which will run you 400-700.

I disagree. You spend more than $10 at mcdonalds. For that price you really can't go wrong even if you just sawzall the muffler off and sell it for $20 on cl. If you're installing the downpipe and driving straight to the tuner you'll be fine. Just stay out of boost until you get there. As far as power, you will see quite a bit more than 20hp with a tune.

Holy **** you should be jumping up and down with joy for getting stage two parts for next to nothing! The DP will require a tune but dont be afraid. Find a local forum member with a tactrix cable and convince him or her to help you flash a stage two map onto your car. You dont have to waste money on a Cobb plus dyno time for a stage two setup. The exhaust install can easily be done in a few hours with help from a friend. Dont forget PB blaster is your friend

Tbh I think k their son died or something, they were selling lots of teenager stuff, but they weren't selling this, it was in their garage and I just pointed at it.

I'm ****ing happy as **** right now, at first I thought I would get like 10hp, but now people are telling me I can gain more than 20? I'm shocked! At this point I wouldn't mind paying for a tune though!

How can I go on about finding a member that would help me get a stage 2 tune? I wouldn't mind paying them for their time, nothing in life is free

If you want a shop to do the install plus tune, I believe Yimisport would be the closest shop for you. Check out the Southern California section here or search for more info.

Why in the world did you haze out the garage floor in the pics? Something on that floor you don't want the world to see?

I don't count calories- my wife does that.

To the OP, if you'd like to use the axle back in the meantime while you wait on your tune, you could get yourself an exhaust adapter. I got my Grimmspeed adapter for around $45 IIRC. You can always turn around and sell it pretty quickly for a few bucks afterwards.
