Test pipe too short!!!
 

did a 1.8 swap motor is in. everything looks nice and lined up. got a 1.8 header with the motor and bought a and 1.8 dp. i bought a ebay exhaust here is the link to the one i got. 1990 1997 Mazda Miata MX5 1 6L 1 8L 2 25" Catback Exhaust System w 3 5" Tip | eBay
the exhayst looks great. all hangers line up. fitment is good. then i ordered a test pipe on ebay. 1 inch to short. if i pill the catback the one ich closer it hits the axle. so i return the test pipe and order another from a different company. same thing. everything bolts up and lines up. but there is exsactly 1 inch between the text pipe flange and downpipe flange. is there different leinth down pipes? anyone have experance with ebay test pipes, are they all wrong? what else can i check?

You ordered a bunch of crap from eBay and you're surprised that none of it fits?

Just cut and weld in an inch on the test pipe

Take test pipe to exhaust shop, pay them 30 bucks to cut the flanges off and weld onto correct size pipe. Call it win.

test pipe
 

good point lol

good call on modding the test pipe that was my next step. just didnt know if there was somhing i didnt know. like 97 dp different from 95 ect.
