yes I did the same thing and changed the muffler to a magnaflow but kept the OEM pipe those things are designed to fit into the stock cat back

I just did speed engineering 3/4s and ORY yesterday and it is slipped right in to my stock I pipe (stock SS catback). Used the stock clamp for the ORY to I. Takes some maneuvering and force to get it all lined up and slipped in, but it's a good fit.

I haven't tried to bolt back up the connecting body brace that's right at the I pipe connection, but I'm pretty sure it won't fit.

Speed engineering LT, ORY, & DMH cutout into a stock catback with quad magnaflow tips. It's the perfect set up for me.

I ran this set up for a while and it was ok at moderate power levels. At higher levels like 400+ the cut outs are probably necessary. At the track, it'll stifle the car.

Pacesetters, TSP Y, stock cat back. It bolted together nicely.

With headers as long as you get a new Y it will all connect properly, unless you run a big outlet Y pipe. Then some adapting will be needed to connect the factory 2.75" size pipe.

If I had a totally stock car right now and wanted to upgrade my exhaust I would do the complete Hooker blackheart headers and true duals system.

BTW, it also sounds terrible. The SE stuff is great quality and price but the Y merge slams the exhaust together and creates a terrible reverberating rasp through the stock SS catback that makes it sound like you just got it off the blocks in your front yard.

I had a fuel tank shield rattle that made it worse. Got rid of the shield and it still sounds like domestic ricer garbage. Going tomorrow to do dual 2.5" over axle into separate muffs.

Agree 100%. It fits, etc, but I don't like the sound quality very much or the rattling at all. In the right RPM range, it gets raspy, too.

Have had Jet-Hot (=Hooker) LTs/ORY into the SLP CME
package I-pipe, and JBAs/Mufflex tubes / SLP ORY now.
No problems fitting the pipe.

ORY rasp I think comes from sloppy construction at the
merge. Seen some with really bad tube-into-tube and
tube stuck in 1/2", never cleaned post-welding. I spent
some time with a flex shaft tool and ball stone grinding
it smooth, up inside, and no rasp after that. Sounded
great through the CME exhaust. If you have rasp no
muffler will eliminate it, you have to kill the source.
