67 side pipes question
I have a small block 327. I need new side pipes, just the pipes not the covers. Mine are 2 inch and they get wider at the bend before the crimps. Can I go to the 2 1/2 inch and still use my stock manifolds??? And who has the best quality and prices?? Thanks

John that was a good question. 2 inch outlets. 3747042 LH32, 3846559A LH30. I guess I'll go with the 2 inch. Who has nice pipes? Car is not all original so I don't have to stick oem. Should I go aluminum or stainless for the price difference??

You might talk to Allens Exhaust - they may be able to fabricate 2-1/2 inch sidepipes with a 2 inch outlet/flange. Not sure how much gain that will get you with 2 inch manifolds. The larger pipes will also be louder in most cases although on a stock hydraulic lifter motor it may not be by much.
I would recommend aluminized. Mine are probably 15 years old now and still look brand new.
