for me i would consider buying the invidia N1 rather than the other two invidia that was mentioned on your post!. The reason why? it is because it has a strong solid support, and robot TIG weld for piping, performance mufflers, and tip to improved strength and durability.

kind regards,

i appreciate the link to the forum good info but still never really gives an answer i was planning on buying a perrin downpipe and a cat back from elsewhere but i dont want to have to buy a tuner right now if this downpipe is going to be setting off my cel..... so my question is if the catted downpipes tend to set off cels or not? or should i jus suck it up and buy a tuner on top of everything?

Well, you can limp a Catted DP around. But, who wants to do that? Just get some EM: either it be a AP or OS. Then get a DP. That way your good to go after you install the DP. All you'd have to do is flash the new map on.

How did the link not answer your question? It says specifically...
Quote:
Do I need engine management with an exhaust? For 02/03 WRX and STI users, no. For 04+ WRX users, it's pretty much a requirement as the open loop/closed loop fueling issue mandated by the EPA causes long term reliability problems with using a downpipe and no tuning. For STI users, the STI was the one exception manufacturers are allowed to have, but it's a wise move regardless as the STI and 06+ WRX users have a good chance of boost creep occuring with exhaust use. Tuning can ease this issue, but the cause/effect/cure of boost creep can be researched via this link.

Catted, straight pipe, doesn't matter. Would still need some sort of EM if you go with a full TBE. That's why the post doesn't specify aftermarket is aftermarket. Also, if you bolt up an aftermarket cat-back to the stock downpipe, you will most likely need an adapter since the stock system uses a doughnut gasket and aftermarket exhausts use a 3" 2-bolt flange.

Probably not, my one friend tried to bolt up a WRX cat back on his 07 2.5L Impreza the other day and it was 4" short.

Coming from experience, i went with the Invidia N1 race exhaust. It is a little bit louder, but the sound when down shifting is a straight rumble. Very crisp rumble in my opinion, although some people might consider it a little bit too loud. Which is solved by the fact that this exhaust comes with a silencer. Shortens the bass rumble of the car and transfers the noise into a crisper/less bass sounding exhaust. Although i'm not 100% sure if all companies will include the silencer. But ultimately, in my opinion the exhaust looks good and performs like a strict racing exhaust, hence the name. Might not be for some people, but if you want that subbie racing rumble this exhaust gives you what your looking for. Although it weights a bit more than Invidia's light weight racing n1 exhaust.
