Are there any decent aftermarket intermediate pipes out there? I see almost all catback systems come with one, but they don't sell the i-pipes by themselves. The only one I have found in a pos looking thing by Walker. The pictures make it look like it has crush bends.

Ideally I'm looking for a 3" stainless piece for a custom system I'm putting together. Thanks!

 

Anyone? I'm starting to think Walker is the only one that makes them, but they are 2.75".

Dynomax also makes some, but they claim they are for regular cab, short and long beds. Anyone know if either of these will fit?

Dynomax also makes some extended cab one but for 07-08.

Talked to Dynomax today and their part number is 55512 for the I-pipe for 01 ECSB, 5.3L. He said it was 409 stainless, but goggle searches say aluminized. I don't care at this point. Looks like it's 3" though.

 

What are you looking to replace? The piece between the Y and muffler?

 

Exactly. I still have the stock one and it's really rusty. I'm going to do a 3" inlet 3" outlet muffler so am looking for a 3" I-pipe. It's a custom system I'm making myself.

 

Find a good muffler shop, they can order any size/type of pipe and have them put it together.

If you were in Houston i could point you in the right direction. Not familiar with CA.

 

awhile back, I bought the dynomax pipe. Its 2.75" where it connects to the ypipe, then goes to 3". Its mandrel bent aluminized steel. It fit my '05 rclb gmc

 

I think this is the one I used, but they dont show a flange in the pic. Im pretty sure it came with a flange to bolt to the ypipe.

If you really want stainless, try contacting Magnaflow for a part number. I think you might be able to get summit to custom order you one.
