What to do with old stock exhaust?

OK, I love my GTHaus exhaust...it's really really awesome. So glad I spent the extra money on a quality system.

However, I now have a stock system laying around. Is this of value to anyone? Can it be grafted on to other WK2 models? If so, anyone want a stock system?

Re: What to do with old stock exhaust?

The exhaust would be no benefit to any other model but I've seen others modify the stock SRT exhaust to fit their model just to say they have an SRT exhaust. Might try putting it up on Craigslist.
If it doesn't sell then try the local metal recycler.

So your saying the added exhaust capacity has no benefit? I seriously bet to differ. Especially on the V6 where the 6.4 exhaust is larger overall and lends itself to better flow characteristics. And if one puts a ripp kit on it that exhaust will help extract even more power

Re: What to do with old stock exhaust?

Did you re-use your stock black exhaust tips? If not what would you take for them?

You mean "beg to differ". It's not as easy as slapping on an exhaust with a larger diameter. In many naturally aspirated cars you'll lose back-pressure when means less horsepower/torque. Read some of the SRT threads that show slower 0-60 and quarter mile times after an exhaust upgrade.

Didn't you say you were a mechanic?

Here's some light reading for you.

I did not re-use the stock tips, but it comes as a unit. I'm not going to split it up. I did need to re-use the stock clamps for the tips for the new exhaust, but the tips are still there.

If anyone local to the PDX area wants it, PM me and we can work something out. Buyer loads.

Don't need your reading. And its been proven also that larger piping does help. And if people are racing then its even better. More power up top where you'll be running. People keep saying they loose low end but here's the problem. They aren't tuning for the exhuast afterwards. A tune will compensate for it. And yes I am a mechanic, yes I am running a srt exhaust on a v6 and yes its way faster with it.

Do you know what's involved in tuning a custom exhaust system?
It's not just plugging in a programmer or throwing it on a dyno at your local speed shop.

Some guy slapping a larger diameter exhaust on his car and claiming it's "way faster" doesn't exactly disprove science.

Your one of those if I ain't OEM it's junk guys aren't ya.

And yes I do know what's involved. So I guess knocking over .4 of a sec off my 1/8th mile times confirms that science to right? I did build my exhaust and fully done my research on it. So yes I really do know what it takes. And yes pipe size is critical to a point

Re: What to do with old stock exhaust?

Wrong ..I've had aftermarket exhausts on most of my previous cars.
This is the first I've chosen to just swap out exhaust tips because I could care less about making a 6cyl SUV any faster or louder.

Sounds like you had other variables that contributed to dropping .8 in the quarter mile. According to an online calc that means you picked up ~35hp by adding an exhaust that you cut and pasted from a Jeep with 6.4 liter engine.

Good luck in fantasy-land.
