well i just put my new HKS hi-power on and man it sounds soooooooooooooooooooo sweet. it only took 30 min to put it on but i had the car on a lift so that helped out alot..i'm gonna take some pics soon so i will post them when i get them...
I HAVE TAKEN SHITS THAT WERE HARDER THEN IT WAS TO INSTALL THAT EXAUST...7 BOLTS TAKING IT OFF...7 TO PUT IT BACK ON,IT IS BY FAR THE EASIEST THING I HAVE DONE TO MY CAR BESIDES PUTTING AIR IN MY TIRES
cat-backs designed for our car don't need welding, only generic ones do.
There were 7 bolts? I only remember 5 (3 from the b-pipe to cat, 2 to the muffler?).
Also, I had a hell of a time getting mine on. I couldn't break loose one of the bolts on the catback, even with a torque gun. I didn't have a torch so I brought it into a shop and where they heated the nut up and pounded on a special socket, waited for it to cool, then torqued it off. It sucked. Those catback nuts rust like nothing else.
