I've heard a few times about having too much back pressure. Well what i'm wondering is if the I pipe that goes from the cat back to the muffler is 3'. Does it really matter if the 2 pipes that leave the muffler are 2.5' or 3', considering you're talking about a foot of pipping on each side anyways. I was thinking of getting, random tech exhaust, flowmaster thunder, or slp loudmouth I want something loud because it's a 305 they're not insanely loud anyways. But, I don't want to loose horsepower or torque getting it because it's too big and doesn't supply enough back pressure. Do you think the slp loudmouth, and thunder series are too much sense they have the 3' all the way threw. Or just the slp loudmouth because it doesn't have a muffler just a resonator? I'd like to hear some info I know there have been many things written about this but I can't seem to find my specific answer. Thanks a lot guy's.

 

I meant to say too little back pressure, sorry. It's a little late and I haven't had that much sleep.

 

Actually, you're still wrong,, I won't get into this again, just do a search on this board about backpressure, look for what five7kid has to say and a few others, that know what they're talking about.

Also, the cat-back is a good mod, personally I would get headers first. Also,I'd recommend the Hooker cat-back, paid $200 for mine req. some fab work. Sound clip in the sig.
