I have an Injen SUS 3" fit perfect, I'm selling for 100.00 plus shipping, only reason i'm selling it is i went with a GT3037S turbo.

 

perrin dp

 

I have the megan o2 housing, downpipe, test pipe and catback. Have been very happy with the product. My DP comes pretty close to the oil pan though, not sure if this is a common issue though.

 

I put my downpipe on yesterday and it sits close to the oil pan as well. haven't heard it vibrating against it though.

it's ichiba 3"

 

Is there any good DP that have high flow cat?

because I want atleast some kind of cat. I heard it smells really bad behind the car if you dont have one.

 

It'll smell like "extra horsepower" if you don't have the cat. hahaha

 

I melted my HFC into a brick which caused to much back pressure that resulted in a very cracked manifold. Not worth it imo

 

I see. thanks.

 

of course, it may have been low quality as well. i won't buy another one though.

 

Road Race Engineering has a great downpipe for the ix. It clears all the parts it is well made. It is full 3" it is reasonably priced, and it uses the stock spring screws and gasget on the stock O2 housing.

 

Your exhaust goes as follows...

-from the engine to the front of ur head through the exhaust mainifold, down to the turbo's hotside, down to the o2 housing, down to the downpipe, to test pipe, to cat-back.

hope that clears it all up for u

 

Go with Tanabe!!! Fits perfectly...yeah it's 2.75" but you won't notice the .25" on a stock or green turbo. It clears the stock bars and oilpan beautifully. Price wise it might be a little more but you can find some vendors that are willing to bargain.

 

speedcorps had the megan dp for160 shipped i dont know what they charge now but thats a pretty good deal i think and it fits fine but the gaskets crap.

 

what kind of gasket does megan use?... for the money megan is great.. maybe if they charge more money then people will stop saying they are a cheap company

anyone with used downpipes forsale please PM me as it seems im gonna settle for a deal on whatever i stumble across.. id love to get my hands on a used ams or tomei

 

as for o2s why would the install become overly difficult? is the location the problem?
