Maybe this is a dumb question, but I thought I'd better double-check. Just got a Hallman MBC from Al at Dynoflash. Any problems running 19-20 lbs boost on the stock exhaust? I plan on upgrading to a TBE soon, but I don't have the cash yet. Should I wait on the MBC install, or go ahead and put on the exhaust when I get it? Thanks for the advice.

 

Install it and just readjust it when you get the TBE.

 

thanks. that's what I thought.

 

I will be putting my MBC on at 19lbs(no higher) w/ my stock exhaust still on. I hold it for a decent amount of the midrange already, holding to redline should help some.

 

yeah once the exhaust is on the gases will flow alot faster so you will need to turn it town just a tad bit you will notice a huge diff once turbo back exhaust is installed enjoy it bro take care
