Default DIY/custom N/A exhaust?

I am spreadsheeting my mods for the MY04 2.5rs when i get it, and I do not have that much money (being a hs student) and so I am exploring the possibility of fabricating my own exhaust (or, which is most likely to end up happening, is that i will contract a local muffler shop to do the dirty work for me) in the hopes that it will save me alot of money. Performance is not that big of a priority (otherwise id be saving up for a cobb) it is more for sound, although I wouldnt mind some gains in power.

The only requirements are that it is not too loud and whiny, and that i do not experience any loss in low end torque.

If possible, i would like a headerback, but if the price is too much, i will settle for a catback or even a simple muffler.

Can anyone relate their experience in performing this? I have seen it done with the turboback systems, but never with a N/A car. Any problems that I will encounter? What price range can I expect?

Lots of people have enjoyed Magna Flow Mufflers and I think you may be able to order them as just a muffler. Stromung, Brullen, are the other semi subtle cat-backs but you can't buy just the muffler. Whatever you do don't go with an Apex N1 or N1 clone they make the exhaust sound like a trumpety Honda Fart Can exhaust as do most of the cheaper mufflers sold on ebay.

I haven't heard much about flowmaster mufflers on our cars. I know Meineke carries flowmaster mufflers and could do the work you want but normally they don't have nice mandrell bend machines. Check Midas I found one of them with a mandrell machine that was only a short drive away.

Default One more vote for Magnaflow

Get a magnaflow muffler until you can save up and do the job right. It will enhance looks and sound. Then, save up for mid-pipe, header, or whatever else suits your taste. I know how it is to be a college student, but don't just throw in a temporary fix to your wants. In the end it will cost you more than if you had patience and got what you wanted to start with. One nice thing about Magnaflow's is if you buy the T-304 stainless ones, they'll last you as long as you own your car, and then some.

Default apexi n1?

i hope you are not suggesting that the n1's make the subbies sound like honda fart cans?

I have an n1 catback, and I dont think it turns the car into a honda....with the boxer engines we have, its hard to make it sound like a high pitched whiny honda...

"Brullen, are the other semi subtle cat-backs but you can't buy just the muffler." Quot


I was just at the Brullen Shop last week. Richard (Owner) told me that he is willing to sell just the muffler. In fact he probably would make a custom one if someone wanted. I saw a prototype of a dual 4" tip muffler that could fit on a subie. (sorta!)

This isn't related to your thread, but I must ask. Why did you go for a MY04 2.5RS when you can get a used WRX for around $16000? When I bought my RS I really wanted a WRX, but used ones went for around $22K when I got mine, and I couldn't afford it. Otherwise I'd be driving a WRX.


Just curious.

I bet insurance had a lot to do with it...but thats just my guess!

Go on summit racing and order a catco high flow cat, then find the muffler of your choice (elsewhere) and get the muffler shop to weld the muffler and cat to 2.25" piping and there you go! Catco cats are pretty good from what i hear, and they arent too steep in price.

1. insurance for a 16 yr old would be killer
2. my parents, and in times of quiet objectivity i can only agree, do not trust me with that much power
3. its only a car, so i figure why bother with an expensive one, the RS isnt that bad of a car. I know the new school rs's dont get any love because of the wrx but it served subaru well before
4. 2.5 liters available for a turbo kit later on

All i need to do is raise money to get rid of the disgusting seats
