Need important help w/ exhaust info. (Mav, regency, help!!)

MustangJon255 · September 11th, 2007, 11:36 AM

Hey everyone. I finally got my car, and installed my Steeda UD pulleys last weekend. My bamachips C&L racer intake are in the mail. And now I just need exhaust! I was thinking of getting Ceramic Coated Hooker Headers with Gibson Mufflers. If I do that, I would have to (i think) cut the stock H-pipe (including the cats) and put it all together that way. Then my 02 sensors wpn't be connected because there aren't bungs for them. I'd have to drill holes and get them connected right? If your comp is set up for it, then your sensors shouldn't throw any codes or anything to the emissions computer right? Cause the tune would make the sensors read "correctly" (obviously w/ no cats)

do i have all this straight? Or am i just pulling this out of my ass??
I need some help here!!

I know Im not Mav or Regency. But I have a little advise. You will have to do something with your midpipe. Cut it? for what you pay an exhaust shop to chop it up to fit, you could replace it with an aftermarket one ( Mac Pro-Chamber ) not to mention you wont have to worry about it leaking for misfit, ect... As for the 02 sensors, get the 02 delete plugs then you wont have to worry about them. Or you could have an exhaust shop weld in new input for 02s. Hope this helps...
BTW- all this assuming your talking about getting long-tube headers...

naturally haha
thanks for your advice!

as for your exhaust dilemma, hookers are a great choice in headers, so are american racing headers as well. be sure you get ceramic coated, its alwasys the best. i think you will have fitment issues trying to connect the tubes to your stock midpipe, so you will either need to buy an aftermarket midpipe (like a JBA H pipe with cats that do connect to longtube headers) or have an exhaust shop custom fab a pipe X or H depending on what you want. there will be bungs on aftermarlket midpipes for the cats, even if there is none. so if you got an aftermarket midpipe without cats (i dont know of any that would connect to long tubes) it will come with the 02 sensor bungs. you get a custom fab pipe, yes drilling a hole for the bungs is necessary. the only time the car will throw a code is if you have an offroad midpipe (no cats) and not tuning the computer to compensate for the missing cats. but if you go with an entire system with an aftermarket midpipe with cats, you will have no CEL problems.

hope this helps

All hail Maverick. Let it be written. Let it be done :wink

MustangJon255 · September 11th, 2007, 04:26 PM

thanks! it does.

So...

Hooker LT Ceramic Coated
O/R H-pipe
and gibsons

will be loud. but wont set off any alerts to emission as long as i have a tune for it? as far as shop computer is concerned?

1FastFox · September 11th, 2007, 04:31 PM

it will be fine. Might highly consider an X-pipe rather than an H-pipe. You will see better gains. And yes, it will sound great...

Bhblondguy · September 11th, 2007, 04:39 PM

the gains you see with an x will be minimal, and then you'll just have to put up with that sound...

I'm for the o/r h

MaverickMLFD371 · September 11th, 2007, 04:50 PM

whether its x or H, if its an offroad pipe, gains are going to be minimal. x is not always more gainful over H. it just changes the sound. the H is going to give you more of a muscle car sound, vs the X is going to give you like an exotic porsche sound.

look at JBA. they do make an off road H pipe and a catted H pipe to compensate for any long tube header application.

2-1/2" Off-road H-pipe
6675SH*

2-1/2" H-pipe with cats
6675SHC
