Ok keep in mind i dont want my car EXTREMELY loud but ok loud for good flow...I was thinking of getting a DC JDM 4-1 Header with the 2.5 collector to a 2.5 magnaflow hi flow cat to my skunk2 megapower exhuast.. i know the skunk2 megapower is only 2.36inch But i dont want to get the 70m becuase thats too loud for me ....Is going from 2.5 to 2.5 to 2.36 extremely bad? and as for mods for car right now just intake...obviosuly exhast next then skunk2 cams and intake manifold But do you guys think thats a good setup? And some questions Where is a good place to buy a DC JDM 4-1 header? Will a 2.5 universal magnaflow cat fit or do i need to take it to a shop to get welded? And how will the ground clearance be?

That's a perfectly fine set up, there's nothing wrong with going with a 2.36" or 2.5", as long as you're not in the 3" or above with your set up then it's fine. 3" is worthless unless you're going forced induction. As for the JDM header, I've heard many say that the ground clearnce is bad, but it's worth it.

That setup will be fine. Make sure to include a resonator since you don't want the noise level to be too loud.

OP. If youre interested in Skunk2's exhaust, PM me. I can get some pretty decent deals on their products.

I suggest you increase your b-pipe diameter to 2.5". Going from 2.5" to 2.36" would be meaningless. You'll end up losing power due to bottle-necking.

Just keep it all 2.5" but get a long resonator or even two of them with the hi flow cat and a magnaflow muffler.

lol obviously you didn't fully read the OP.

Just spring for the 70mm Megapower. 70mm is 2.75in you'll have room to upgrade.

I have the magnaflow and love it

I have the magnaflow and love it, they are cheaper on ebay but I wanted a warranty (the salt on the roads here in winter kills an exhaust) so I got it here magnaflow 16901, or you can try one of the vendors here, they are always running sales/specials. either way its a great system and very easy to install.
