Mating an Invidia DP to different make CBE
 
I'm looking into installing a turbo-back exhaust on my '11 wrx sedan. I'm looking into getting the Invidia catless DP and either a magnaflow, perrin, or cobb CBE. Has anyone had any issues with installing a set-up like that? Thanks.

Would recommend staying away from catless dp's on the newer models.
you could need a little reducer to line them up, just something to look into, but you should be okay otherwise.

^this. Don't forget you need to tune for it.

Just out of curiosity, why is the catless DP a problem with the newer cars? I understand the emmissions' part, but is there other issues with them?

Cause possible boost creep/codes. They are more dirty. You don't gain much more hp than a catted one. You may get like 5 more hp if you're lucky with a protune.

Also emphasizing on what the bear says above, you must tune for a tbe.

Okay, that makes sense. Now, I know that the catted DPs' are more pricey than the catless, and I'm not trying to drop a lot of money right now. Would sticking a catted DP with the stock exhaust for the time being be foolish? I already have a shop that I trust that's going to do the tune once I change out the intake and exhaust.

No it wouldn't be foolish. You just wouldn't be getting much sound from your exhaust. If you can live with that then go for it. Or you could wait until you get the money and go for the tbe.

Personally, I'd wait until I had bought the whole "system" before installing (there's nothing wrong with buying parts at different times). That way, you only have to tune one time.

Who is your tuner/shop?

What about a custom cat back? I'm pretty sure psi does custom exhaust if I remember correctly. I was looking at them to do some work but never got around to it.

That's what I've done with past vehicles, but honestly I didn't even really look into that. Doesn't matter now, just dropped the hammer and got the Nvidia N1 CBE. I'll put that on, and save some funds to do the Stage II to my car. Thank you all for the comments and ideas.

Hey guys. I just got an Invidia downpipe divorced wastegate installed in my 12' WRX. I haven't had any problems with it being cattless only that the stock midpipe is a smaller in diameter. Does anyone know were I can find a midpipe that can be installed to connect the Invidia downpipe to a SPT Catback? I need it to be 3" all the way.

arewmors 11-12-2013 05:31 AM

^Wouldn't you just want an adapter like the link has below? That will mate up the exhaust

I don't need an adapter. The down pipe mated with the stock mid pipe just fine. It's only that there was a small problem when they where tuning the car. The dyno kept showing an unusual dip in the graph. They tried everything they could to get rid of it. They came to a conclusion that since the exhaust goes from a 3" diameter (down pipe) to 2.5" diameter (mid pipe) and back to a 3" (SPT Catback exhaust) that there is interference with the flow. So they recommended me to get a 3" mid pipe. The only thing is I can't find one that will mate the Invida to the SPT Catback.
