I have flowmaster 70 series muffler witch is made for the camaro, It has the 2 1/2 inlet and duel 2 1/2 outlet's. I was wanting to know if i just put one 40 series flowmaster with a 3-inch inlet and a single 3-inch outlet would it sound better and make more power

 

First thing, are you sure its not an 80 series you have? And yeah 40 series sounds loud... But in my opinion, if your going to go all the way to a 40 series muffler with a single outlet, why not just go to a Dynomax Bullet muffler...Cheaper and louder...My favorite muffler on the market now...:hail:

 

I gotta Spintech 4" and that sucker sounds goooood!!!

 

My friend has a 87 iroc with a zz430 in it and a miniram and he has the Hooker super comp 1 3/4 header's and the mufflex 4inch flowmaster system and it sound's great. how do you think this would sound on my car do you think i would lose a lot of toruqe

 

I'll hafta agree with 92 zzz28, Spintechs do sound totally awesome, But they are $70 more then a bullet muffler, thats the biggest reason I like the bullets...Sound good at a cheap price!
