I use the little Summit Turbo mufler. It is waaaaaay lighter than stock. What I should have done was open the exhaust pipe up to a full 2.50 so the engine could breath
You won't see much of a HP gain due to the limits of the L-36 making power inthe first place. They are not too loud but they do drone. I like the drone myself
Below 5200rmp you won't see much of a gain, but the car as you see in the sig did break under the 16 secound mark.
You must also be aware that you are giving up a lot of wieght to any car you run agianst from the start. Don't have any sound clips or part No. for you as I've slept a lot since then, but I don't think you'll be to displeased with this mod. Mainly because they only cost about $25.00 U.*. (this should inclued shipping and tax).
Haven't been back to the track since I've installed the ZZP throtle body yet, but will go in the fall...... to hot in Texas right now
