I'm doing Gotts mod. Electric fans. Exhaust with rear cat delete and true duels.
The truck has a little over 1000,000 miles and will see a lot of highway miles as I plan on doing some traveling.
Questions
1) What size exhaust ? 2 or 3 inch 2.5
2) H pipe worth it ? X-pipe
3)What mufflers ? I want it to be heard but not obnoxious. Deep sound. Borla or magnaflow
4) What electric fans work the best ? Flexalite
5) Any other ideals greatly appreciated 
Trying to get the bang for my buck NEED gas mileage and HAVE to have POWER 
Thanks for input |
