IF I BOUGHT AN AFTERMARKET DOWNPIPE FOR THIS THING AND THEN SAY AN APEXI N1 CATBACK,THE DOWNPIPE DOES BOLT TO THE CATBACK RIGHT?SO I WOULD BASICALLY BE TAKING OFF ALL OF THE EXHAUST COMPONETS?JUST WONDERING CAUSE I WANNA DO A NEW DOWNPIPE/CATBACK AND WANNA REPLACE IT ALL WITH PERFORMANCE STUFF.ALSO HOW MUCH POWER CAN I GAIN FROM THIS ON A STOCK CAR.ONE MORE THING,IS 3" OK TO RUN??THANKS AGAIN ALL!

 

make sure you look into that before you choose your exhaust, a lot of exhausts you would have to cut/weld to make a downpipe/cat fit. the nice thing about the N1, not only do i personally think they sound the best and perform the best, apex makes a bolt on downpipe or if you want a cheaper one roadrace sells a downpipe and high flow cat that will bolt on to the apex n1 directly, thats whatI have
