AND then when you want everyone in a 5 mile radius to know you're ripping on your M3, you can open & the valves and let the S65 sing.

The difference between building your own & buying a pre-valved system (Gintani, Evolve, iPE, etc), is that the systems are designed to sound good whether the valves are open OR closed & with minimum drone.

By fabricating your own exhaust, you run the possibility of making the exhaust sound like crap or unintentionally creating drone.
thank you for the reply. i have a challenge sport x-pipe with a mesiesterchaft gt2 which is extremely loud. while it doesnt bother me at all some cop near my house stopped me and asked me to change it and if i did he will keep an eye for me and will be giving me a ticket the next time around.

i hate to change my muffler so i want to compromise and take it to a good muffler shop and costume make a valve system and if anything ill add a set of resonators to reduce any drone or rasp
