The only restriction in the LM1 is the slowing of the exhaust velocity due to the bends in the pipe. Regardless, it's still the highest flowing catback on the market. It's essentially just straight pipe.

The Pacesetter y-pipe, on the other hand, is a piece of crap IMO. It's flattened in spots and the y-merge is a disgrace. Not to mention the fitment and banging issues I hear plague it. I wouldn't run it on my car if I got it for free, but that's just me. I'd get the TSP y-pipe if I had to choose a shelf y-pipe to bolt up to Pacesetter LT's.

If you like ear-piercing loud, then that's what it'll be.

I would skip the pacesetter y then. If you don't want duals then I would have a custom y fabbed using the Flowmaster merge and full 3" cat back.

+2!

I 1 7/8" AR LT's catted Y and the LM1 on my 408 and I'll be buying a magnaflow bullet muffler today to replace the resonator.

Stock displacement .. I liked it. Hell, I like it now but I KNOW a ticket is waiting for me. Not to mention, tracks have laws about noise. I don't have a Db meter but my ears say it's too much.

LM is a str8 through design, its probably less then alot of other catbacks. Your question doesnt make much sence.
