I am currently running MBRP 4" duals with cat delete. Is there enough benefit changing to a 5" turbo back to make it worth while. Or will the decrease in EGT's be so minimal that it's not worth the money. BTW as far as Hp goes I don't plan to go any further than what you see in my signature, since this is my daily driver and worker truck.

 

The only real benefit will be the sound. I noticed a slight difference in how fast my turbo spooled, & maybe 100* egt. But the sound is great.

 

This has been covered several times over, try using the search and you should find lots of very good info.


Like stated above the only real benefit at your power level is gona be sound. Totaly worth it imo but ive never heard 4" duals.

If you want the deeper tone, its worth it, if you dont care much about the tone, its not wroth it. You would need (in my opinion again) at least 600hp to NEED 5" and really you can get by with 4" way past the 600 mark as many have done.
