I recently got a muffler delete for my car and it backfires a little bit when my engine is warm with my exhaust.

Is there anyway to get more pops and crackles? Like maybe aftermarket cats/midpipes/resonators? (headers too expensive atm).

Also can't do a tune for it because I'm not able to find any tuners in the chicago land area for lexus.

Thanks

Your current pop and cackle is likely due to leak induced. When upstream of o2 sensors it induces errors. Yours being downstream, gives the unburned fuel a chance to reburn when o2 is added.

Be careful what you ask for....
