Hey guys what is the difference between the stock tl-p and tl-s exhaust system? What is the diameter of the two pipes? did anyone feel a difference in performance after installing a tl-s exhaust onto tl-p?

broly

its the same

sbuswell

I always thoughts and believe I have read on this forum that the tl-s exhaust is a larger diameter and has slightly better flow. Correct if I am wrong.

I think TLs is a bit bigger in diameter

yea i agree with sbuswell but I just wanted to see what u guys might have to say becuase I am sure someone here knows and tired it out. I called the dealer and they told me the part numbers are different for the tl-p and tl-s b pipes so there has to be a difference in diameter

sbuswell

i think tl's is 2.5" piping and tl-p is 2.25"

broly

and something with the b pipe
but he's not going to get massive results with it
and to the naked human eye there is barely a diff.

sbuswell

right, but barely a difference in exhaust diameter means barely a difference in performance gain. But 5-10HP gain is not much compared to 225HP or 260HP for that matter, but take the same car 225HP and 235HP and see which one is faster. It will be obvious the 235HP is faster. So to the eye it is not much different, but I real life there is a solid difference(but not huge by any means).
