Back in 1999-2002 I had one on my 99 TA until the car for heads, cam & long tube headers etc.

My 99TA was very slightly louder and a filer exhaust note with the SLP Y pipe and SLP Dual / Dual catback than a couple of 99 Firehawk's with the standard Y pipe and SLP Dual / Dual. Both Firehawk owners asked about why my 99TA sounded better. No one else ever noticed the difference.

Power wise on a bolt on only car my guess is the SLP Y pipe is worth 0 to 2 hp. With a heads and cam set up it might be worth 0-4hp. It was viewed as basically a worthless mod. My 99 TA with the SLP Y seemed to be about 2 to 4 hp better than similar mod'd stock Y cars at the local dyno. I have no idea if the car was naturally a little above average or if it was the SLP Y.

I would do other mods for the money.

Looks like it could use a better Y-merge, like a Flowmaster unit. Smoother flow....

I have one of these on my car. Little deeper exhaust tone and less rasp. The merge is definitely much nicer than stock. Can't say what power gains if any.

It improves over the stock y-pipe in that the LHS pipe is not flattened.
