question about ypipe and ipipe
question about ypipe and ipipe My first time messing with my exhaust. I have an aftermarket three inch ypipe but it seems that it's a tight fit going into the factory ipipe. I took it to an exhaust shop and they said they couldn't do it because the factory clamp on the ipipe is welded. Is this true?

Sounds like that exhaust shop didn't want to make it work. There are a number of different struggles depending on which y-pipe you have, but all can be made to work with a little effort. Most y-pipes are meant to work with a 3" i-pipe, and I believe the factory is only a 2.75". You may need to use a reducer, or have the exhaust shop expand the stock i-pipe, which most can do. They may need to cut the clamp off and use a new one, or just weld the y-pipe to the i-pipe.

It takes about 30 seconds with an angle grinder to knock the welded clamp off the exhaust and grind it smooth. I've done that many times.
I've had more than my share of exhaust woes myself.

I'm at O'Reilly and just for a temp solution, they have a three inch pipe stepped down to a 2.5. Ill go buy a grinder to get the old clamp off and see what I can do with the stock ipipe

The various Y pipes I've had were all a very tight fit
to the "factory" (SLP CME) I-pipe. They all needed a
lot of griefing to get more than half an inch into the
end. And you need that or will have to crush the pipe
and then you're stuck next time, big time.
You could consider slitting the I at least as far in as
your band clamp will cover, that's just hacksaw /
sawzall / cutoff wheel work.
There are also larger band clamps which can be a
butted-pipe union, if you have equal diameters.

Most guys do tend to purchase an aftermarket catback prior to moving forward to the headers and y-pipe, and yes most aftermarket catback's do come with a 3" intermediate pipe.
