Thinking about doing 3.5" downpipe and Cat delete into stock 3.5" exhaust
I dont want to straight pipe the truck, but I would like to have a little more sound and get the turbo spooling faster and evacuate exhaust gas a lil better.
If I'm correct, the OEM exhaust is 3.5" after the cat. SOOOO i see these 3.5" down pipe and cat delete combos online for like $130-$150. Thinking about just bolting one of these up to the stock exhaust.
Will I get any more exhaust note with that setup if i retain the stock muffler? Any benefit in performance? I'm not interested in a huge exhaust setup at the moment and dont want to lose any low-end. Its a stock truck that I just run Vivians street tune on. Its plenty of power for me Its not a race truck, its a crew cab long bed with a 6-speed manual, It breaks the tires loose when the turbo lights now that plenty fun to drive.
If it had a lil more exhaust sound, and spool a lil quicker and maybe help lower EGTs thats all i am concerned with. BUT a turbo back exhaust really isnt very expensive either, so if I NEED to go with a 4" I will, just seems to me that 3.5" exhaust the whole way back would be plenty for the whp Im making.
