so not too long ago i got my exhuast done on my car, mac lts, mac h with weld in cats to some super 44 flows and 3 in tips. i looking to get some 3.5 in tips after i get my gt bumper, the 3 in looks too small. for some reason when i had them weld in the cats i think they just welded in regualr magnaflows. so the million dollar question now is, does putting on regular cats have any bad effect on my exhuast set up. should i go back and get some high flows? or would just keeping the reg cats be ok

 

If they didnt do the job right they need to fix it. Post some pics of the questionable cats and we may be able to help

 

wait, so they put in magnaflow cats? or magnaflow mufflers? how do two sets of mufflers sound? 0.o

 

its magnaflow cats and flowmaster mufflers, but the question is should i have gotten some high flow cats

 

magnafllow cats should be high flow cats.....

 

This.

Magnaflow cats are highflow style.
