Hello All

I'm looking for the best overall emission legal exhaust system. Header to tail for a Forced 396 LT4. I know this is kinda lacking all the info but..

Over all what Headers, with air and EGR?

Cats? I have to run 2!

Then Cat back system?
The Mufflex 4" kit looks good and I have read other really like them. But I know there are other options!

Does anyone out there make a full kit? I was looking at the Mac full Mids with cated Y pipe. But cant find out any info on the system for a big inch setup?

Anyone that can help me???

Thanks
Ross

if you turboed then why would you buy normal aftermarket headers? i have the edlebrock mids that are 100% emmisions legal i like them.

I like my mac mids but I don't know about a 396, they might hold ya back.

could't you run lt's with cats on both of them and have true duals .

dont know about that one.. im thinking about that for CA. keeping the cat i have where it is and having it put onto the collector.

or maybe his sig say TURBO

if you move the cats from the factory location they will not pass visual emissions

depends on the inspector checkin it, mine passed full visual and sniffer. if they're leniat enough go for longtubed with emission, mine are great, get a good exhaust shop and have em fab up a y-pipe with two cats (trust me, will fit much better than some mass produced piece) and then pick what sounds best from there back www.ls1sounds.com is good for that

They don't make a 2 cat emission legal system!

Anyone else?

Thanks

i would just buy the headers you want and have a good local exhaust shop work the rest of it

I know I can go to a shop, but I have a good mig and a bunch of know how. So far I'm thinking about a nice set of Mid Tube's with all the emission fittings. Into 2 high flow cats Ypiped into a Muflex 4" catback.

I hear all about guys hitting pavement with long tubes! I want to keep my clearence!

Can you run a L.T. setup and not have them hanging on the street? If so what set-up?


Thanks

kinda depends on luck, if you arent lowered usually you'll be ok but you could get a bad set of headers, mine have about 6" of clearance but some people arent so lucky, mids will work great tho over the stock manifolds. most mids come with a y-pipe but you'll probably have to flange in the cats, i say to flange them in so you can remove them if you want after emissions. just make sure that if you do this to get smaller cats so those dont cause clearance issues.
