Exhaust Tips....Resonators?

Just checked the link to Summit.........

I did not know such an insert for an exhaust was even available........

Give me some pro's and con's here..............Pressure problems?

Doesn't really apply since you don't have headers, but here goes:

Pros: Will quiet your exhaust down

Cons: If you dont tack weld these inserts in, they will rattle when the collector expands.

Adding a restriction so close to the exhaust ports/in the collector is bad on two counts. The engineers who designed these headers know what they're doing! The collector acts as a means for the negative pressure wave following a positive pressure wave out of any given primary tube to act on the rest of the primarys thereby helping to extract exhaust gases. When you stick something in there that not supposed to be there, you throw this whole tuning theory out the window.

The next problem is that the gases haven't had a chance to cool, and are still super hot and expanding. IMHO I prefer to install mufflers (essentially a restriction) as far away from the collectors as possible because I believe that the muffler (restrictor) will not have to flow as much gas (as measured in CFM) as it would closer to the header collector as a cool gas takes up less volume than a hot gas.

7demon2 and 64cuda are right. In your case, some shorty glass packs would work well and probably sound great too. :thumbup:
