i forget what year your car is, if its a 96 pull them things and flip al gore off

<sigh>

Though I think very little of Al Gore, I do think it would be nice if our children and grandchildren had decent air to breath.

With that in mind, it is best to keep the cats. I am currently reworking my exhaust system and plan on moving to Magniflow cats from the 99000 series. The mufflers are being switched to Flowmaster 40s with the original tips welded back on.

You won't benefit with the V8 and no cats.

You gain RASP, but not much HP.

I have some fresh cats, recently smog certified in Cali, only 2 as they come from a gen ii. I can measure to make sure they fit. Will sell for half of retail.

Personly I have the third cat gutted with stock mufflers for now. But I believe that some perfomance cats or even some oem ones would be fine. I ran a few days with the flex pipe unbolted. The sound is awsome at idle and even driving around a bit but. It turned a lot of heads. It takes very very little time to get annoyed with it though exaust smell is killer to. You'd need a nice set of mufflers to keep it relitvly quit but I would feel bad for the person behind that had to smell it or our kids for that matter. Besides you want the back pressure that the cats provide for the v8. I think the v6 probly benifits from no cats more so than v8.

The problem with running open and no cats is not the back pressure. Its sizing and tuning the system right. Simply unbolting the pipe at a point in the exhaust can increase hp a little at one specific point and **** the power everywhere else if not tuned vs the stock setup. Believe it or not but I would be wiling to bet a fair amount of thought and trail goes into the exhaust for best over-all performance which is why we have such difficult time doing better/cost and money/trail and error.

A open system may perform great with a smallish pipe and not cats low restriction mufflers and a pre-determined lenght.

Once again though you have to choose one or the other usually, or do we...?

Most the time the choice is everything low speed drivibility or high rpm hp.

Problem with our smallish motor is to achieve both at the same time, but if you can what a advantage!

I had a huge exhaust leak and replace it with this
Magnaflow 23533 Direct-fit... It sounds maybe a tiny bit better then factory, definitely better then an exhaust leak. The problem is that the fitment is way way way off, at least on the setup shipped to me. Be prepared to make some serious adjustments if you use this exhaust. Otherwise it works great and I am happy with it.

 

[SHOZ123]

I got two OEM Y pipes soon to go to the scrapper......

 

[theboneskes]

What are your OEM Y pipes for, and would you ship them, or where are you located?

 

[stephen newberg]

I will take one of them off your hands, Paul. Contact me at:
