Re: The ultimate DX/LX header/exhaust FAQ

they match up, the bolts that came with the res pipe are are quite a bit larger. I might just drill them out. I'm curious because i saw a pic of another megan header with the same small holes. To remove this ad, register today for free or log in if already registered!

Easiest way to do this, like Triz said, is buy an EX header and catback exhaust.

Then go to Summit Racing and buy 2-1/4" inlet/outlet Magnaflow hi-flow cat. It's a real cat (not a test pipe), is OBD-2A compliant and costs $70. While you're there, buy a 4' length of 2-1/4" pipe ($10-12) and a 2-1/4" formed flange for $5 (P/N: WLK-31885) .

We're at $85 plus shipping right now.

Then head over to Mandrel Bending Solutions Ebay store (Click this), buy these items:
1 piece of 2-1/4" U-bend pipe - $12
1 three-bolt 2-14" flange - $4.25
1 two-bolt and 1 three-bolt gasket - $6 ($3/each)
1 oxygen sensor bung for your post cat sensor -$4
1 L-shaped hanger - $1.76

That's $33 plus shipping from Mandrel Bend Solutions. The whole new, truly 2-1/4" downpipe and real high-flow cat has just cost you $120 plus shipping for the parts. You will reuse those spring bolts already on your car.

Now take your new EX header, catback system, and box of exhaust parts to the nearest non-chain muffler shop. Point to the box of parts and the car and say, "I want all this stuff on my car, and I want all the stuff that's currently on my car put in these boxes. I'll be back in two hours, here's $150."

Go stuff some food down your gullet, have a beer, and then come back to your brand new, tits sounding exhaust.

I'll get your pics in a second Triz. I'm pissed off at the car and don't feel like going outside right now.
thanks a lot man. im gonna be getting a skunk2 catback but i was just wondering what you think the best headers are for their price.

Re: The ultimate DX/LX header/exhaust FAQ

^ stock EX unless your looking for the best aftermarket header. Then I would say DC sports race header- continently proven to yield power gains.

The forsale section would be the place to check out. Usually craigslist comes through with parts like that.

Re: The ultimate DX/LX header/exhaust FAQ

Yeah I dont know anything about 6th gen exhausts. I"m pretty sure if I could look at an lx and an ex engine bay I could tell you whats up. Most of the info still holds, just the parts are different.

Re: The ultimate DX/LX header/exhaust FAQ

Yes they make catback exhausts for lx/dx models, or you can use the aforementioned lx to ex exhaust swap, both will work.

i also wanted to make sure that the piping for the 4dr is the same as the 2dr concerning the cat converter since the original was done on a 2dr and im doing mine on a 4 dr.
