At the same time I'm getting headers installed I want to add new exhaust tips to the car. the SLP LM1 tips have always been kind of plain Jane, and boring looking, I really prefer the square tips that the cars came with stock, but I want it in stainless steel. Since I'll be getting an ORY for 1 3/4 in headers, will it matter what outlet the tips fit? One pair says 2.5 in outlet and another pair says 2.25 in outlet.

Here's the cheapy ones from Ebay, should I avoid these?

Here's the ones that got me interested in the first place, but that price is steep, just for tips.

I actually had a pair like that, and they caused a weird humming type sound at low rpm's. Had to cut then off and go with something different. Personally i'm more a fan of the round tips anyways

 

I'm pretty sure the LM1 has 2.5 inch tailpipes so you'll need tips to match. What you're really going to want to worry about is how obnoxious your car is going to sound with with headers ORY and LM1, you may want to look into a bullet muffler to replace the LM1 resonator. Also if it's not too late I'd consider 1 7/8's headers, there is no down side to them over 1 3/4's headers and they are worth a good amount of power if you add heads or a cam.
