HOW DOES THE SPD Y PIPE DO WITH STOCK EXHAUST ? TRUCK GOING IN MONDAY TO MUFFLER SHOP FOR EXHAUST GASKETS AND STUDS . HOW LONG BEFORE INTAKE SIDE GOES ? MAYBE DO TWO MANIFOLD GASKETS AND STUDS ? ? ? OR JUST DO SIDE THATS BROKE ? LUV THE STAINLESS HEADERS JUST DONT NEED THEM. I THINK Y PIPE AND STOCK EXHAUST IS A GOOD THING. WHAT YOU ALL THINK ?
The SPD ypipe will be an improvement with the stock exhaust or aftermarket exhaust. There is really no negatives worth mentioning to install one on a 99'-04' 5.4l truck.
There are exhaust manifolds and there is an intake manifold, the intake manifold does not have bolt breakage issues. If you have no leaks or broken studs on one of the exhaust manifolds you could wait to have the studs replaced. It will only be a matter of time until they break however.
If you start seeing rusted exhaust manifold studs, I would just replace them all.
Ok not shouting LOL. I guess capital letters means shouting ! Thanks for response. Exhaust side back two nuts GONE from rust ,others badly rusted also a leak that caused engine light to come on , its off now, leaking so going in for gasket and studs exhaust side. Intake side are rusted bad also .I like the old advice IF IT AINT BROKE dont fix it ! Or should I have those studs replaced now.I shouldnt have to replace gasket on intake side right ? THANKS AGAIN.

Thanks bud ,you mean intake and exhaust correct ? See my other post. You think I should not have to do anything on intake side .

It sounded to me like you are thinking one of the exhaust manifolds is the "intake side". Both exhaust manifolds are just that, for the exhaust. There is not intake side as far as the exhaust manifolds go.
The intake manifold is on top of the engine and routes air into the intake valve in the heads.

Thanks not a mechanic , so both manifolds are exhaust ! Why does one side seem to be most problematic ? Is it a rule of thumb to change both sides gaskets and studs. Thanks again
I punched in spd y pipe on google this afternoon got MORE THAN A FEW NEGATIVES on y pipe some say it changed the whole sound of the truck ( made it sound like a 6 cylinder ) ! ! ! I dont want that ! Others say it DIDNT help gas mileage ,some said it got worse ! MOMA ME AH ! NOW IM CONFUSED . It is going to be around $ 270.00 plus shipping ( includes a couple of hours for muffler shop ) It is a WORK truck. That we tow sleds and small 19 ft bow rider in summer. WHAT TO DO. Could buy some other little gadgets. ? ? ?
I recently purchased and had a Stainless SPD Y-pipe installed on my 5.4 250. I did the y-pipe a muffler and a tune all around the same time so i'm not entirely sure if it did help mpg or power. but I can say that having done all that i'm getting 3-4 mpg better on the highway and 1-2 country driving.
As far as the negative reviews... make sure you're comparing the correct things. the 99-00 year is debatable as to whether it does anything because the stock y-pipe does flow pretty efficiently. However i believe most of the negative things i read when i considered purchasing the y-pipe were gripes from the v10 guys. Not really sure why they have so many issues. but there are many many fewer negative comments about the spd y-pipe from the 00-04 group then anyone else.
If you have an earlier truck , like a 99-00 they came with a rams horn style front pipe. I dont see much improvement for that application. 01 and up is a different story.

Yes both sides are exhaust. One side of the truck can get more crap thrown up on it from driving than the other which can affect the manifold studs.(I noticed that on my truck) One bank could also could be getting hotter due to a lean condition however it is probably the first thing I mentioned.

That only applies to the 6.8l V10 engine. It does not apply to your 5.4l V8. The V10 is an even fire engine which can sound weird. The 5.4l is an odd fire engine which is known to sound good.

You did y pipe + ( just muffler ) no other straight pipes ? double or single exhaust ? What is the tune? Is that a expensive chip or computer thing ? Woul like to get a FEW MORE miles per gallon myself. Thanks

Yes that is correct. I did the 01-04 Ypipe and a mac 3" flow path muffler with stock piping other wise. and i have an Xcal3 from 5startuning. The tunes i have are 87 performance, economy, and tow. The higher ends of my numbers are using the economy tune. But, there was still an increase in MPG with the performance tune on there, just not as much because i was driving a little more aggressively....
I bought one for my dads V10 years ago when they were on Ebay so I do not know what their lead time is nowadays. I have full long tube headers on my V10.
Contact Mike at 5 Star in the link below. If he has them in stock he can ship it out quick.

Do not get your hopes up too high. I can barely eek out 15mpg empty ALL highway in my V10 with all the mods I have on it. All stock it was the same mpg. My mpg did not change. Of course I am running the performance tune with 87 fuel.
