Muffler delete

I heard a few vid clips of the SS with the muffler delete. Its really growing on me. Are there any power lossess though running no mufflers?

I am a V6 owner so definitely not an authority. But we did dyno my V6 with my cut-outs open (no mufflers) and closed (with mufflers) and there was a power loss when the cut-outs were open.

Ok, thx for replyin. Thats what I was afraid of. I was lookin at one car that has this done and they were sayin he picked up a lil power but i dunno. I have done extensive dyno testing on my race car and it usually made more power with mufflers than straight headers..

Why not consider the electrical cut-outs like I have. It's the best of both worlds IMO.

Not a bad idea, but I was tryin to keep the cost down plus Im not crazy about the look of the stock mufflers. I just stumbled across a chambered exhaust from Stainless Works, its almost identical to the factory chambered exhaust I had on my 67 RS/SS...Decisions, Decisions....

I already pitched my stock mufflers and headers...so I defintely know what you mean. I spent more than I should have...and that being said...I wouldn't change a thing...and I'm still paying the bill.
The cut-outs are worth a little sacrifice...I promise!

Electrical cutouts and muffler deletes are two TOTALLY different things and several people have posted on here that there were no gains on the V8s, but I don't recall any losses.

I WOULD expect losses on certain vehicles with cutouts, but with the muffler being at the end of the exhaust, I wouldn't expect any losses.

Those with ACTUAL experience should chime in.

This is mine on the dyno , I have the SLP Loudmouth (muffler delete), it put down 373 at rear wheels. I personally love the sound. I think it had a whole different feel after the muffler delete, almost as if the powerband changed....Its not the greatest video, if I find more I'll let you know.

I had mine cut out and straight pipes welded in place...there is no loss of HP at all doing this. The sound is another thing altogether, some love it, some hate it. Electric cut outs aren't cheap by any means plus the install is a bit involved ($)... My set up was 200 out the door
