Tuning with stock exhaust

[Penner]

This time stock exhaust "Cat delete" and modified stock airbox. (And a map.)
That is all.
Probably the best bang for your bucks.

Thanks, that is a good jump. Can you buy the crossover alone or do you have to buy the silencers as well?

Just for clarification, the cats are actually in the stock cans on a Roadster. The pipe underneath, from pictures I've seen of them cut open, are just resonator/collector boxes.

You can get the "cat delete" alone.
We build some for our own use, but Paul Bryant sells them.
