I have been having a huge amount of trouble with my exhaust lately. I have what is in my sig and the moroso spiral baffle muffler just WILL NOT HOLD TOGETHER. I have broken 2 of them so far and I need something more durable and was wondering if the Racing Beat presilencer makes a large decible difference or whether it is geared more towards just a tiny bit of muffling and a simple fix for the backpressure problem with the six ports? I bought a three inch diameter straight through Dynomax Muffler that is made for v8s and it isn't much more than a straight pipe......Does anyone know how far in to the pipe the perforated center protrudes on a racing beat presilencer?

Does anyone have any other ideas as far as presilencing? The moroso spiral muffler works really well to give the exhaust a deep tone and muffle it a bit but does not impede the exhaust flow as much as a true baffled design does.

Thanks in advance guys!

 

I believe the rb silencer works well, but mostly changes the tone so its deeper and not so tinny.
