Cat back question
 

Currently have a test pipe and installing a catless downpipe and intercooler this week but I don't have a cat back still running factory exhaust. Wondering if not installing a cat back im losing out on a good amount of power?

Catless downpipe + fuel pump internals = a MUST

Yeah internals have been upgraded from the beginning haha

I had a race pipe than installed a 3" cat back and did notice an improvement. That was the last mod I did though.

Stop killing the environment.

You will get more power from a tune and 3" or bigger intake, if power is what you are after. And those two mods will cost roughly the same or cheaper than CBE.

I got my cbe for super cheap (reason I bought it) and when installed didn't notice any felt power. One of the threads here discusses it helps with flow though.

I honestly wish I would have put the money toward intake and a tune. Hope that helps you.

CBEs don't add power, at least nothing you'll notice. It's a sound mod.

I had to get a retune after putting on my catback because I wash hitting +2 psi more then target. I dont have dyno results to compare, so I wont sit here and say it added power, but it improved flow and adjustments needed to be made.

I would upgrade the intake first as well. I would recommend the 3.5" Corksport. Also, once you get that catless downpipe in there, trust me, you aren't going to want more sound. It doesn't really make the sound too much louder inside the car, but you will notice a ridiculous amount of noise bouncing off nearby surfaces (like when going through tunnels, sitting near concrete barriers and other cars) because your car is, in fact, a lot louder. This isn't something I expected when I installed my downpipe and I absolutely love the stock CBE now. It really sounds great.

Cbe adds more than people think. Especially if you have cats deleted.

I was worried about the sound adding the cat back with the downpipe, part of the reason I waited on it when getting the downpipe. I haven't installed the downpipe yet (Thursday) but I'm sure the exhaust will be louder. I guess I'm more wondering if the investment is really worth it.

I only bought the exhaust as the last item and I bought it used from the market place. Someone just sold a complete cat back for $250 so they do come up now and than.

Was going to buy it haha just figured I better wait and hear my downpipe before hand.

Yes but isn't the majority of the power gain from deleting the cats rather than the actual CBE

Yes that's true but if you have a 3" race pope or down pipe aftermarket exhaust are 3" instead of the factory 2.5" and a muffler where as most CBE have resinators. I thought the same thing and when I bought a used Cobb it was because I liked the sound however I was surprised to see that i felt an improvement.
