I'm going to check the junk yards for this part... It's the y-pipe that runs from the exhaust manifolds to the collector down by the frame... My question is.. Is the y-pipe the same beds and bolts up the same at the collector on the OHV as it is on the SOHC? I'm going to go look for one because the OHV's have no pre-cats with 02 sensor holes and I'm wondering if the swap is bolt on, less restriction.

I plan on deleting those pre cats as well as the last cat in the system, only leaving 1 on.

Thanks guys!

 

the first two cats are the important ones.

plus you wont gain squat by removing them.

i removed mine, drives the same, not worth the hassle IMO, they are high flows, i removed mine and welded in magnaflow high flow cats along with all stainless pipe, sounds good, runs the same.

 

Not lookin for any gains other than sound. That's the only reason... Ask shane... My truck is way quiet and always has been and I want something different now! I've had a super 44 and super 40 on it and neither one was loud. Time for an upgrade...

I've been told the cats on the new rigs these days are mainly high flow so that's good, but the pre cats are going to go if the y-pipe is bolt on from the OHV motor. Then the last cat in the system is going to go also, leaving only 1 in the system... All that's needed.

 

Why don't you retune after deleting them so that you can take advantage of having less temperature in the combustion system. Less backpressure will also allow you to advance timing without knock. Do you have a tuner for your truck?

It will be hella loud, and thats pretty cool. You will need to fool your computer by using anti-foulers on the rear oxygen sensors like I've done so many times. If you need help PM me and I can get you the link to the thread on this trick.

 

Tre, you had a Delta 40 and a Super 40 currently. Super 40 sounded aweseom on my truck. Why yours is soooo damn quiet, idk.

 

My vote, cutouts and dumps before the cats. It will be as loud as possible. Then can be legal too.

Not sure if thats possible with cats in the ypipe. Looks very doable on the ohv.

 

hey shane

i saw that there were three "CAT looking" things within the exhaust... are there two cats and a resonator??? if i take out the resonator it should make it louder rite??? i did it on a civic(yea i know totally different app) and it was night and day difference

 

dude the ohv pipe was the same i would have sent you mine. but i got tired of it laying around so i sent it to the scrap yard.

 

Ok so I pulled a y-pipe off a 94 and one off a 98 (not sure exactly on the years) and total was $10. They're each a bit different so that's why I grabbed em both.

Next week at school I'll do the swap and figue out which one works better and what mods and stuff I had to do. I'll be taking pictures... Jp7, I'll PM you with what I need to do since I don't have a tuner.

 

Here's what they looks like:

 

looks like it should work but i dont see the purpose. there are other ways to get sound. mine is pretty load with my magnaflow

 

Purpose is to get sound from my truck. It's never been loud and I'm gonna attack it at the source and work out until I get the sound. That's really the only reason. I already have exhaust but that just isn't enough lol

 

i am gonna be extremely surprised of its the same distance being one is a cam in block and one is a modular motor.. modular are usually at a different angle of a V... should be interesting.

if they dont work i need one for a 98-00 for sure...

 

Well see I'll have 3 different y-pipes when I start the swap... So it could be a combo of multiple y-pipes for the finished product. We'll see though...

Zach I could probably get you one but shipping wouldn't be so cheap. You're better off getting one at a local JY.

 

ive got the same set up as beard but ive got dual in dual out..

its LOUD!!!

 

I wanna do that! One day, but this is the first step in that direction! lol

 

Why not ditch the muffler tre?

 

I've tried two different ones and neither one was all that loud. If I just ditch it all together I'll lose back pressure, so not happenin lol

 

no flowmaster is gonna make good sound imo.

 

you forget where i live.. none in the junk yard is better then mine.. there is a reason i only get my parts from TN

 

truth

 

truth

On a v8 it might. I still prefer a dynomax or magnaflow then.

 

You should hear Shanes and Austy's trucks in person. They both have flow's and sound freakin amazing.

 

So I found a good size chunk of 2-1/4in galvanized tubing I could use for a cat delete. Took it to a local exhaust shop and since they can't be affiliated with cat removal, he said he could put the bends in it if I told him what bends to make, so he didn't get in trouble. The tube for this only needs to be moved over about 2.25-2.5in (with a dog leg like bend in the tube).

Tomorrow I'm going to buy the spark plug anti-foulers for the 3rd O2 sensor and I'm taking my cat-less y-pipes to school tomorrow to install them and remove the 4th cat.

Here's what the guy did for me... ($10 for the bends and the flared end and free tubing from school!):



Oh and I have 2 MORE SD 3rd's! One came off a 2006 and one came off a 2008. So the year varies on these gems!



One of them is spoken for by Toreador, the other is going to be for sale. I have 1 other one too but that spoken for by FRXLT!
