Exhaust tuning

Hey guys i just recieved a Dynomax 2.25 duals kit for my camaro and some flow tech headers. I have everything to install them an expect gians over my stock system.

How much will I feel the dual exhaust and headers. Also what will I have to do to my 305 TBI to get the most out of this exhaust system> I have an open element an 6 degree timing. I have a B&M shift kit installed right now too.

I am not using any mufflers just straight 2.25 all the way over the rear axle

No tuning required for that setup. Now if you change the cam or heads, different story. Intake and exhaust mods are ok and don't require computer tuning

Re: Exhaust tuning

Can I ask you a question? I'm looking at installing a B&M Kickdown Kit and was wondering if you used one and if so what you think of it?

This is how I see it. Intake/Exhaust mods DO need tuning to get the most out of them. Even the factory engine has plenty of power hidden in the stock tune to make it worthwhile.

Makes sense, especially with what you told me. I thought he was asking "Will my car run after I do this without a tune?" which his car would run just fine, but like you said not at its peak for what it has.

No because the money is better spent to buy your own tuning equipment. I would also take the opportunity to switch your ECM out to use the faster more powerful 93-95 TBI truck PCM.
