How much horse power have I gained with the removal of my mufflers?

[JonB]

Applies to 92-95 only:

If you add only K+N filters and Smoothe tubes, that adds 15HP.
Pop the 2 mufflers and gain 15+ more! Total 30+.
Great Bang4buck!


If you still have old OE inlet filters/hoses, the muffler-delete probably gave you +20 by itself......DO ADD HOSES/FILTERS (from ParstRack?!)

If you add hi-flow cats, you can expect 5-10 more, and VERY loud.

) I dynoed my bone stock 94 RT at 351 RWHP. I then added K&N's, smooth tubes, and removed the mufflers and dynoed 389 RWHP!! A total increase of almost 40 RWHP which equates to even more at the flywheel!

Very nice bang for the buck, not to mention the increased throtle response, better sound, and MUCH cooler side sills!! Look for my previous post if you want to look at the dyno results.
