SLP may start making their 2.25" y-pipe again.

[bgs]

A member over at another site got some mail from SLP. I'd like to get one
to finish off my exhaust. I'd have to modify it a bit, but it would be nice
if they do start making them again..Ck it out. This was dated very recently.

Dear Jess,

Thanks for your interest in SLP products.

Due to strong interest in these Y-pipes we are considering making them again,
and
are evaluating that product right now.

Regards,
Jon Hedges
SLP

Here's pic of what they look like. Nice smooth bends, 2.25 at the banks
going into a 2.50 merge pipe. No price yet on the new ones if they
decide to start up again. >

nice y-pipe. keep us posted. after i do my headers ill be lookin for one!

[ZR1 S10]

I got one of the ones when they used to make them!!

Has to be one of the best mods I bought for the truck. 1000x worth the money!!!

[ZR1-S10]

Let's hope they start making them for more years this time. Last time they only made y-pipes for 97' and 98'. If they don't can I still use one for my 96?

[bgs]

I have a 92. I've no doubt with a bit of modding I could make it work on mine. I read a
post over at s-series forum in the exhaust forum on a sticky all about what it will fit.
It is worth the read. I think the diff between the 94-96 and then the 98 up is the
length of the merge pipe which can be worked out.

I did talk with a sales rep, and he was telling me in order for SLP to start a run
would req 200 orders or more ! Whew. I have not talked to the man in the above
thread. He is higher up and may know something this tech I talked with doesn't. His
name was Don. I hope to talk with Jon Hedges this week. No telling how this will
turn out, but if 200 orders at 200 + S$H are req = $40,000 preorder at the old
prices I can't see it happening.

ok guys big problem i have an 2002 s dime with a 4.3 and i have the precat well like the dumbass i am i had my boys completely cut the y pipe and run true dual with glass packs well obi didnt like that and now i'm running around with the damn ses light on all the time the trucks running like sh*t sorta seems like i've got a lil loss of power assuming that the exhuast is to free flowing i ran it with 2 inch and nothing bigger now i want to go with flow master 40 series and go back with the y pipe only problem is i cant find a y pipe for anything newer than an 01 or something like that any advice on where to find one would be appreciated i know it aint gonna be cheap either i did find a site on the web last night that has them but for 1 i dont know if they are the right ones and 2 E X P E N S I V E :o/ THANKS GUYS

You're gonna need that y-pipe in order for your ride to run right
again. I don't know anyone who has a y-pipe for the late models.
I know Walker Exhaust Systems has some for the early ones but
don't know about the late ones. You may have to go used. Here's
a site that may help.

to answer your quetions yes the y pipe will fit newer s-series trucks(the t-series is quetionable). here the problem with putting on newer trucks, from the e-manifold flanges to the post cat flange is 1 peice. You can get away without haveing the precat and not set off anylights and most off the time it'll even pass a visuale sence most inspection. you can cut the cat off and reweld to the 2.25 y-pipe or you can spend the 200bux on an aftermarket cat with the same flow numbers.

most people are taken in by the old myth a cat robs power(however true this may have been with the pellet type cats it's not with the new honeycomb cats) so they remove it and the truck runs like crap not because of the cat but because the comp censes there is no cat... well...actually it sences that the cat is going to be malfuntioning soon and resticts fuel to meet the +/-% check code. because of the ever changing nature of the a/f mix as it reactes to ever changing conditions you cannot simulate this with anything outher than a computor program and a piggy back prosesor.

any decent exhaust shop can weld a new y up for you. mine did mine for 130. ihe used 1 1/4" merged into a single 3". that was a major upgrade.

[mattownsa97withmafproblem]

what the hell is the precat for then? the air injection? so are you telling me than any downpipe aka y pipe will work from the v6 AND I DONT NEED THE FRIGGEN PAIN IN THE ARSE PRECAT shoit i didnt know that, what about having a custom y pipe done with one cat ?

[mattownsa97withmafproblem]

question what would be better a single 3 or a 2 and a 1/4 system?

[LilYellowZQ8]

Single 2 1/2. 3in would be too much flow and would kill your backpressure and kill low speed torque. You could probably get away with a 3in system if your engine was built for it and using boost, but on a N/A engine, it will hurt you more than it will help.

1.25 ? Why not 2.25 for the bank pipes ?

I've got a 96 and I'm using the 97 one. It bolts right up!!!!!

[ZR1 S10]

Mandrel > Crunched bends

[bvr775]

it won't hurt you none. It's only a 1/4 hp(if even that) if you go with a 2.25 pipe.Like I said thats a 2.5" pipe. I don't start worring about mandrle bending untill i hit the 10grand mark on an engine and i'm trying to sqeeze out an extra 0.02 in the quater.

[mattownsa97withmafproblem]

so 2 and a quarter front pipe will work fine with only one cat and 2 and a quarter dual out will work?

[mattownsa97withmafproblem]

oh yeah if ya didnt know i'm not driving a 97 anymore it's an 02 with air injection so that might change the ball game 2 a precat and a cat

[bvr775]

that's all one peise on an 02. if you can find someone who will remove the precat it's no problem to have one made, but if you can't I thinck you can use a silverodo y-pipe from 2000up. Let me find a pipe size on them before i say for sure.

[mattownsa97withmafproblem]

yeah i know it's all one piece that's why i was wondering if i could have one made and only use the cat and not the precat

[mattownsa97withmafproblem]

oh yeah that reminds me i no longer have the ypipe we hacked it up in order to get it off the flanges so now i have true dual from the front flanges back so like i said i'm gonna wind up having my boys at midas make me one i just dont know what size yet thats why i'm asking you guys for advice

[bvr775]

I'm not sure i would trust midas but if you've got the hook up go for it. I have my work done at Duels (small plase in nederland TX) and he lets me get away with allot. It's a private shop and the guy been bending pipe for 30 years. He did my roll cage too.

not meaning to start a argument or anything but i got a HUGE gain out of my y-pipe and 3"exhast.

well I read your sig and you don't have a stock engine


crane 260/276 cam & valve springs, pro-mag 1.6 rockers, msd 6AL, crane pmax tuner

for those with the stock engine internals scavenging is a must

[nomaboy]

I put the exhast on their way before i did the cam swap. i just got done with the cam this weekend.
the 6al and tuner were done about 3 months ago. i have had the exhast sence december.

[mattownsa97withmafproblem]

yeah i've got a major hookup there i know it's weird them being a major franchise and all ok all in all what's the best route i should go with? i mean cut to the chase :)

[nomaboy]

see if they will do it. some places won't touch anything B/F the cat some will. the guy i go to is awsome. he is a small shop and dosn't have a problem doing anything i want. if you have a hook up then i would think they would do it for you.

[mattownsa97withmafproblem]

yeah i do he doesnt care about the cat cause we did it all under the books for 200 :)
but you didnt answer my question thought, ok ok let me tell you what i have done so far intake true dual throttle body msd 6al underdrive pulleys and soon to be iridium plugs and taylor wires so whatca think i should do about exhaust? diameter wise and so on?
