GMMG exhuast Knock-Of?
I've seen the pics,all they use is the chambered style mufflers..
(!!summit!!) sells them and I am sure many other places do too (just the muffs)
Then have a shop fabricate the GMMG style rear bends/exit...
could you probably get the same sound for less cost?
any1 try this.....late night ,bored,mind thinking..lol
hope this won't get a ban
The resonator is just a powerstick.
