is there a performance gain to getting catless DP ? and will it still pass emisions if i put it on?

Also can i use for example a invidia dp and still use the cobb ap

What do you guys suggest for a DP with the SPT cat back?

[KiTsuNe]

you go catless and it wont pass emissions.

if you worry about boost creep EWG!

[stidriver31]

EWG? and so do you not suggest a DP cobb ap and spt cat ack exhaust or if you do what dp do you suggest?

[KiTsuNe]

i suggest a 3 inch down pipe, a catback and a external wastegate kit. AP is a given though

this thread will discuss the different between divorced vs bellmouth. People should read this before they state their opinion to which is better

I went with a COBB catted downpipe since it's suppress lots of turbo noises in-cabin and is not noisy. I couldn't get something noisy actually.

u know u still ownt pass emissions with catted eiter. ull pass a sniffer, but not the test.

It depends on which state your in.. I pass emissions in Illinois with my invidia v2 catless because all they do is check your cel on your obd port and if your not throwing anything, you pass.

I'm probably going to end up going with Cobb when I finally burn up my OEM cats.

It's expensive, sure, but you get top notch quality and the money goes to an American company. While I'm not a "buy American" nut, I do prefer that my money go to Americans before Chinese whenever possible.

true. im in cali so u fail either way. so might as well get more power while ur at it.

I vote for the Invidia V3 catless. That's what Im after right now.

They are like 300 bucks new, and then the catted version is like 500-600 bucks. That's one expensive cat...

[07 Flt4bxr]

^^exactly. so pay 300 for more power or pay 500-600 for less power and still fail smog.(in cali)
i went with invidia v3catless and love it.

[stidriver31]

so even with a catted you still will fail?
WHat do you guys suggest i do: new dp same SPT cat back or all new which ever you believe tell me what product you suggest. thanks

[KiTsuNe]

depends what you want, if you want something pretty stealthy just get a dp and leave the SPT catback

[stidriver31]

i was thinking about that is that a safe option if i want my motor to last etc.
also what DP do you suggest ? to go with a stage 2 AP
