New to GP could use some help.

[06 GP GT SC]

So I recently bought a 2006 Grand Prix GT supercharged great condition with 50k on it. It needs an exhaust and would like some recommendations, also how do I figure out exactly what engine it is? ( L67, L32) like I said I am new to the GP world. Any info or performance upgrade suggestions would be greatly appreciated.

Is the exhaust rusted out?

If not, I wouldnt change anything with it, we have a terrible exhaust note with the 3.8 motor, most will drone and sounds like poop.

Only a select few mufflers can sound okay, like borla.

And you have a L32 motor.

It's an L32

What defines the l32? Yea I was rear ended and it blew out a muffler n the cat I put a new bumper on and now just the exhaust.

L67 = L32

L32 is just a newer design with changes. The timing chain cover is slightly different and the Pistons rods are different.

But really its all the same, same block, same heads etc etc.

If it's an 04+ supercharged motor it's an L32. It has a gen V m90 and a dbw tb.
