No as long as its from the cats back.
If you did anything like headers or hi flows or x/h pipes it would need to be. |

The only thing I will do is define what type of headers.
Shorty header-no tune adj Long tube header-tune adj Anything cat back is ok and will not need tune to be adjusted. But do not exceed these pipe sizes Si/so 3" max Si/do 3" in 2.5" out If you go bigger than these you will start to rob the motor of it's back pressure and you may lose low end torque. Lars

88Racing I had already ordered a Banks Monster Exhaust which has a 3" intermediate pipe and 3.5" tailpipe. It claims to cut backpressure up to 79% and increase flow up to 138%. Is this going to kill my low end torque?
By the way it is a SI/DO |

I went to the site and examined what you had ordered and it's a great product. They did the exhaust design different than most others. The pipe y's after the muffler. So basically they are using the same muffler for the si/do and the si/so. Other companies use the muffler to split the exhaust. It should make the truck sound great after breaking it in, in about 2 weeks. Lars
