high flow y pipe...

[welcome2daSHO]

bought a high flow y pipe from sho source and just got it today, im wondering if anyone else bought one and im trying to figure out if the dents in the rear manifold pipe are supposed to be there or if this was damaged in shipping...

what do you all think?

it seems like it got crushed somehow...but then again it could have been done like that from the factory so to have equal flow for both sides of the engine.

Looks just like all the ones that we have in stock.

Must be to keep it clear of the rack and subframe.

alright great, i kinda thought it would be to even the flow seeing as though the front bank has a lot more curves and longer to travel the rear bank doesn't have as far to travel so they restricted some of the flow so it would be even...ya that makes sense...

Both of those look sharp.

They look sweet, let us know how they are when yo get them on.

I put one on my 97. Fitup was not perfect. Had to bend the mount that connects to the tranny near the right axle. Then had to get the exhaust nuts on and tighten them to get the Y-pipe flanges to match up. Thought I would have exhaust leaks, but seems OK. One big difference is weight. The Magnaflow weights almost half of the stock Y-pipe. 29# vs. 17#.

Not sure if I notice any performance gain. Slightly louder. Maybe a little in the top end, but sometimes feel there is slightly less bottom end.

Oh well, I have an 08 C6 vette now. All the performance I need. I'll keep the SHO's.

Nice plug...I see what you did there..

 

[kikkinasphalt]

can you get these without cats?

 

[LOUDSHO92]

No you cant.

 

[kikkinasphalt]

No you cant.

well crap, i suppose ill have to have one made.

I know that Kirk at NESHO makes catless Y-pipes, and I'm sure that Doug at FPS can fab up a set for you as well.

 

[SuperHO]

what're the gains seen on a V8 y-pipe? I didn't even think they were a restriction.

Made one my self, works great too!

missed this post!


explain!

What about the OBD2? It monitors the cats for efficency (sp?) and will flag the light without them there, or is that something you can delete with an SCT?

[warmonger]

you can delete them w/tunning or you can make some mil eliminators for about three dollars.

 

[SuperHO]

someone explain a little more about these MIL eliminators.....

 

[SASHO91]

Basically your'e tricking the computer to think that the cats are still there. From what i've seen, they are just capacitors and resistors wired together, then wired into the plug for the O2 sensor. What it does is mimic the signal of the O2 sensor.

 

[SuperHO]

in other words, it tells the ECU the 02 sensors are operating perfectly??? So this could solve my fuel economy/random 02 sensor code????
