test pipe=failed emissions
high flow cat=basically same performance, better sound, better smell I would assume, more eco friendly, legal

 

Mmm.. I forgot about magnaflow. Well, i'm going to ask you this, since you have a very similar setup to what i'll have.

I have a AEM V2 installed, and soon i'm gonna add a Megan 4-1 Header, and Apexi WS2. Whats your opinion on the Magnaflow high flow cat?

http://store.summitracing.com/partde...5&autoview=sku This is what i've found for my D17.

I just want to see what you think, because if i'm not mistaken, I rememeber you have a magnaflow cat. And as much as I hate raspiness and test pipes, I thought it wouldn't be too bad, and was hoping the WS2 wouldn't sound too terrible, even with a test pipe.

 

WS2=sex in your ears. lol.
anyway, it's a good thing you asked me this, because when i first had the WS2 i had a test pipe. it sounded really bad and raspy. A test pipe with a WS2 is probably the raspiest exhaust i've ever heard.
the magnaflow one sounds pretty good IMO. It's a little louder than stock, and maintains the deep quiet tone of the WS2. With the test pipe the WS2 gets higher pitched and it's pretty bad sounding.

lol. i have a slogan for catalytic converters.
"High-flow cats: it's just the right thing to do."

The only time i would say a test pipe is not that bad to have is in MobstaMan's situation with the Nawssss and all.

 

Yeah, I love the look and sound of the WS2. Mobsta also makes fun of me alot for wanting it, he always says "Your gonna pay $400 something for a stock sounding exhaust?" and i'm like "I don't want a fart can, and I don't want something that sounds too loud, I don't wanna sound like all the other ricers out there."

Well, the magnaflow one IS cheaper.. And hell, its a cat. And it would save me from doing the defouler trick on the test pipe. Yeah, i'm gonna run nitrous too once I get my Header and exhaust on. I don't really wanna join the K20a2 band wagon, and i'm tired of everyone bashing on the D17s. But hell, with a cat and Nitrous as long as you don't miss a shift and clog up the cat, you should be good lol.

 

and about the megan test pipe you mentioned, FYI skunk2 makes a cheaper one that sells on ebay for like 95 bucks. not sure about for the D17 though.

 

Yeah, the only things i've ever seen for the D17 are.. eBay test pipes, Megan 'high-flow' test pipe, Magnaflow cat, and Random Tech high-flow cat. So my options were pretty limited, but now that you've englightened me, i'm pretty sure i'll go with the Magnaflow.
