buy a pacesetter Y pipe for ~100 bux and be done. that 5.3 does not need dual 3" exhaust. single 3" is fine. single 4" for a highly modded 5.3

 

Agree

 

Single does NOT have the effects of duals. Agree?

 

Not sure what your asking...so ill put it like this.

I built the engine for this car, it made 448hp on a single 3" exhaust pipe. The muffler is at the very rear of the car under truck, its dual out. 3" single is plenty for a 5.3

 

Sound effects. Different sound all together. Nice car tho.

 

I had to cut 1/4" off last time and probably have to cut an inch off this time. You think the pacesetter y will still work? And does it dounut on the end of y or is it weld on?

 

the weld is ugly, but not 1" ugly...cut the collector as closely as possible and the y should slip over. single 3" is PLENTY for a 5.3 IMO.

 

What I'm really thinkn about is gettn pacesetter y like u said then cutn y in half. Dunno if it's set up like the factory 1 where u can do that tho. U gotta pic of the y cause everythin on Internet is more like a cut short t more then a y in pics?

 

K after research the 1 for 07-10 looks like it has more the bend I need then the 99-06. Any suggestions?

 

get the pacesetter Y, and do not use the clamps that they provide. Mr. Gasket has some straps that work better and allow you to pull the exhaust apart one day. the pacesetter clamps crimp the exhaus tto where you will have to cut it off if you ever need to remove the transmission.
