well i installed some longtubes on my SS this week. i ended up using the catless y pipe, arp studs, msd wires,stainless band clamps, single 3 inch all mandrel to a corsa dumped. now its suppose to be a corsa sport but i think its a touring. its so quiet crusing and idle but when you hit all hell breaks loose.

besides needing a tune bad, the truck is screaming. runs awesome. only bad part was having to massage the tranny crossmember a little bit so the y pipe would hit it.

CORSA FTW. no drone, no rasp, all tone.

but does anyone know which way they get welded in? that might be way its quiet lol. when you look inside i have the little hole first then the perferated stuff at the back.

 

On the bottom side of the muffler there is a little weep hole that goes down towards the rear of the truck.

 

see i think its in backwards. but i love the way it sounds. at idle you can tell its not stock but barely hear it. crusing sounds like a hybrid lol. but when you lay into it its awesome. hands down best mod every

 

correction... bolt on mod lol
