Will these mate up without issues? The test pipe is 2.25" and the catback is 2.5" in diamater.

 

it will depend on the flanges. but i would try to find a 2.5 in test pipe. also i've heard that invidia isn't that good of a brand. look into something thats not a ripoff.

 

I already bought the invidia test pipe. Bad quality?? I've got a invidia downpipe and g200 exhaust on a WRX and it is great quality, the exhaust cost me 600$ alone. downpipe was 280. First I've heard of Invidia being bad quality, brand.
