I would like to know what is the best sounding and hp making exhaust kit available............i know a friend of mine had a 3" pipe all long with a brullen exhaust and the sound was awesome...........i like when it pass to a grumble sound a low rpm and f1 sounding at high rpm...........and would like to keep the original downshift backfire

 

best exhaust = no exhaust

 

Seriously, this subject has been beaten over the head and drag around on the ground until it's all raw & ****.... You might want to search for like 8million of the posts about exhausts...

But, since I'm posting... I like the Magnaflow from RRM
But Ultimate Racing also uses a Magnaflow muffler and offers cat back option...

 

Yes it has been covered MANY times. Please search. I suggest reading the NOOB thread at the top of the general section, it will answer a lot of your questions. Feel free to ask me any questions you may have also. I wont delete this, just close it.
