Do you mean the inner pipe? The OEM pipe are 2". What you need are the in 2.25" so you can put over the OEM pipe. Hope that help.

 

What's a safe length to go with?

 

tip 1! tip too is too thin :P i like the rounded ends :P

 

I like the first one.

 

The Borlas look great too. Is there a picture of anyone with the Magnaflow tips?

 

i measured the tips from the GFX rear lip. its 6.25 or 6.50 inches long. didnt really measure it properly. will the 7.5 stick out too muchh?? i want them flush with the rear lipp

 

The one I'm looking at doing is Rolled-Round-Angle Cut
part #35177, 4" Diameter, 6.25" long, 2.25" inlet.

From what I measured on the stock tips (non-GFX) they were 5.5" long. I'm debating on getting the GFX rear from Sewell's promo., then I will dicide what tips to get.

 

Wow those are expensive!

 

Any website that you buy them from run about $60 ea.

 

I agree thats a lot for tips....I would just pick up a used exhaust and do it right knowing they are that much plus labor if you have to weld them on....

 

hmm i dunno about that. used tanabe or hks will run u about $450 + labor. set of tips, about $120 + labor. pretty big diff to me.

 

damn that's exp for just tips...i'd save up and just get an axle back...might as well..ur only off a couple hundred

 

not sure why one would pay $350 for flowmaster when Borla is $60 per. they are just tips, purely cosmetic and i don't see that much diff. in the appearance of the two.

 

so are most of these being welded on? or are there others like the GFX that can be screwed on?

 

the borlas have a clamp that is tightened down on the pipe (phillips head screw). a spot weld ensures it stays secure and prevents theft. (Midas $20)
can't speak for the other brands
