just put on american racing long tubes and all i can say is WOW!. not even tuned yet, well worth the money
i think he meant mufflers but I to am confused. Long tubes and no cats is worth quite a bit of power. Around 30-40rwhp depending on the set up. Swapping mufflers not so much but couple all the components together headers mid pipe over the axle tubes and mufflers and the entire combo works together to net very nice gains.Boss 738 said:I think you are mistaken, I think you will see a noticable gain by going to Long tubes and no cats
there is power to be had in the over the axle tubes coupled with a straight through from the mags and articles I have read. But just pure axle backs maybe five at the most is what I have seen and that's how much a dyno can fluctuate on a car so to me it's nill.Sean said:Axle backs don't add anything, they are pretty much for sound only.
20k for a motor? You guys know that when a motor goes it doesn't mean you have to buy a crate motor....just need usually a short block or long block which can be had well under 8k for the long block. The short block is around 4k for a nice built one.Shaun12 said:Minus the CEL, do you have to get the motor re-tuned? I've been eyeing up a new H-pipe and Long tubes, but don't want to mess with the motors tuning...the thought of buying a new $20,000 motor on a car that I've only made 2 payments on makes me ill.
