DP and UP... make my decision for me...

I'm due for emmissions by the end of July. Therefore i'm planning on purchasing a Down pipe and Up pipe by the end of the summer (AKA, within a few weeks)

 

I've read a lot of posts on each and every brand and still cant make up my mind. Is is worth it to pay the extra money and go for the COBB catted or will I get the best sound/performance out of catless and which kind?

 

Right now I have the Megan Racing CBE and I'm thinking of getting the MR down pipe simply because the price is so low. (around $200) I've also been looking at Up pipes and have been torn between Grimmspeed, Invidia or the STI up.

 

What setup do you guys reccomend... please make up my mind for me.

you could also go with a 07+ lgt up pipe since that is uncatted as well.

i've given mine away.

 

but i went with the grimmspeed - nice piece.

and if you say the MR downpipe is $200, that's a good reason to go for it.

I would not run the car without cats. Yes the Cobb catted DP cost more but the exhaust it cleaner (less nitrous oxide and carbon monoxide). I live in a state where they don't check emissions. I'm not sure how your state checks. You probably want to pass the emissions check in the future.

didnt' see that he wanted to go catless.

probably explains why the downpipe is $200

Well CT is pretty strict about emissions but Ive seen cases where people have gone catless and still passed. Its a matter of price really. If I can get away with a catless piece for cheaper then I'm leaning more towards that. Especially since Ill have that two year window where I won't have to worry about emissions. How does the grimspeed compare to the stock 07? The aftermarket is wider right?

I'm going to preface this: I am not an environmentalist. I get shit fuel economy and don't care. i track my car and burn 2-3 tanks of gas a day. I don't recycle like a should. I don't own a Prius, nor do I want to.

 

A cataltic converter is the most effective dollar for dollar pollution reduction meathod we've ever seen. It is almost single handidly responsible for keeping air in the LA basin and Sacramento Valley near breathable. Too expose your follow citizens to this to save $100-200 and maybe get 2 hp is reckless. The difference between a catted car and an on-catted car is just so dramatic in terms of pollution.

Oh, I expect to get hate for this, but completely removing pollution control from a mondern car is just giving a middle finger to the earth and its inhabitants.

That's my lecture, and I don't want to shit up this thread anymore,s o I'll leave it at that.

 

I have the catted invidia DP with an STI UP (which i don't mind because I still ahve a cat and newer LGTs don't need them). I'm very happy. Got it from the GB (there's one going on right now).

^^ Yeah totally. I don't believe for a minute that global warming is man-made, but shitty air quality IS man-made, and that's just a health issue.

Well said!

an uncatted car also can smell pretty bad.

 

personally, i run a cat because i like to do my little part but i'm not going to give the OP shit for having an uncatted car if he wants to... cars are raced all the time without cats. i believe NASCAR doesn't use cats nor does any other professional organized racing.

Get an Invidia catted DP.. will mate better to your MR catback b/c they have the same flange type

Thanks scooby, thats what I like to hear. As far as the whole pollution thing.. I am environmentally conscious I just wanted to get information on the different options available. I think I will go catted since I will need to get emissions in another two years anyway.

I'm running a Cobb cated downpipe and Grimmspeed uppipe and I've very happy with the setup.

 

I'm not sure what flange your Megan system uses but I'm just bolted to the stock catback so the Cobb fits like it should (shrinks and uses a doughnut gasket). Might want to look into what fits your catback.

i'm running a cobb cated downpipe and grimmspeed uppipe and i've very happy with the setup.

Turbo xs Flex UP on my LGT works PERFECT

perrin up, cobb dp, a bit spendy, but been on the car since 06, never had an issue whatsoever. You get what you pay for....in most cases

Very happy with the same setup for some time now.

Running an invidia up and catted down. Excellent as far as i can tell.

Cobb UP, Cobb catted(reeowrr) DP. Bought the UP new for cheap$$, the DP NIB from another member on this board for $450 shipped. Running Borla exhaust. I live in Mass where they stick their finger up your A_s every time they inspect your car and I always pass emissions. Catless reeks, smells like hell and gives me a headache. Search around for a used Cobb/Invidia w/cat.
