Exhaust upgrade...DONE!!!

Looks like I finally got the wifey on board for this. I have a shop that will do this... cut into the exhaust pipe just as it swings over to the existing muffler and come straight back with a new matching muffler and tailpipe. This keeps the H-pipe system. I guess this is important for this system to work. Last time I did this I just went with two separate pipes and mufflers

Re: Exhaust upgrade...

Doesn't that leave you with a small section of a single pipe? Not that it is critical but it will be a restriction.

On mine they cut out the "Y", took the left branch to a new muffler and tailpipe, the right branch to the existing muffler. And "H" pipe is easy to add between the two as all you need is to burn a hole in each side and weld the piupe in between. You only need a hole, as there is no high flow here, only pressure equalization.

They did all this in 45 minutes for $189......

Re: Exhaust upgrade...

So they cut out the y section and made it flow the way it should. Thanks. What year is your CV?

Cool...what did you notice first? I am hoping to pick up a little on the mileage. I get about 24 or so around town. 27or so on the highway.

I have been told and I think I read it here that I can expect around 8 to 10 increase on the horsepower.

Re: Exhaust upgrade...

If you are getting that kind of milage I wouldn't change anything, LOL

The duals actually add a little rumble, even though I have the stock muffler on one side and a ordinary after market muffler on the other (nothing hi-flow).

According to Ford it adds 15 HP, 224 to 239. Lets face it you are really not going to be able to "notice" that....it just "seems" better......

I just didn't want it to look like grandma's car, so I like the twin plumes of vapor coming out the back on a cold morninig......

Next is a black Marauder Grill for the front, instead of that grandma plastic chrome.....

Re: Exhaust upgrade...

Well I did it. I pick it up today at 3PM. One question...do I have the H-pipe installed like the factory or go without. I am getting two new mufflers so the back pressure is the same, the shop didn't have a match for the stock Ford muffler.

$220.00 out the door. Pretty good price I thought...

Ok...just got off the phone with the guy. I asked him what he would do go with an H-pipe or without. He asked me if I was going to keep this car forever and I said yes. He told me to go with an X-pipe, the H-pipes were old-school. So add another $50.00 and I get the X-pipe. $270.00 total.

Re: Exhaust upgrade...

Got it back...he did a great job! Looks clean and sounds just like I wanted...deeper and not too loud at all. I will take it out of town soon to see how she does on the open road.

Re: Exhaust upgrade...

Where did you get the X-Pipe from, or was it custom built at a shop?
Was it mandral bent?
