[7391417]

I am looking for any and all info regarding after market exhaust systems for my stock 73 1.7 I really like the look of the monza system with its four tips. I wouldn't mind if the sound was louder or more sporty sounding as long as it sounded nice, you know either nice and strong or "race porsche" like, what I don't want is my 914 to sound like a "Go-Kart." can you say civic with a muffler that you could fit a soccer ball in?

Any experince's regarding sound, durability, quality, performance and value of the following sytems would be appreciated:

Monza 4 tip
Manta 4 tip
Bursch
Sebring
straight pipes (megaphones)

Thanks
