Resonator Delete, Good? Bad?

[Outlaw Throttle Jockey]

I've got the Blastin Bob 11dB deletes (straight pipes). They sound great at WOT, but are still pretty quite at idle (a bit more grumble). Cruising is a bit better then stock too. The drone did increase, but not bad enough for me to regret install. If I had to do it again, I would. Check out vid.

Something to remember... If you have the 350 HP version w/ the different suitcase, like on the R/T or SRTD, then you must think twice about the resonator delete. I did it on my SRT Design, and it is way too loud in the interior. I'm going to need to get the Blastin Bob's kit, to quite it back down, and I'm not sure which one yet, but straight pipe is crazy droning at 2000 RPM.

Where can I find the Blastin Bob's at a reasonable price?

Then I ask if he can install my posi-quiets for me and he said those pads are ****?? I'm like "You really don't want my business do you??"

what shop did you go to lol

Again thanks for the tips! I went by today and met with Brian (SOCALSRT8). He has the two tone flat black lx with Magna Flow exhaust and custom wheels! Rediculous car by the way Brian!

What a great car with the perfect sound. The Magna Flow is for me, already ordered!

I want sound but not a loss in HP!

Give me the LOWDOWN!

SHARK22 this is an awesome mod! I had this done a few weeks ago but unlike most i had same sized pipes mandrel bent to replace the resonators. Picked up 19.9hp. Yes, i did a before and after on the dyno. Oh and it sounds great, with no drone at highway speeds at all. A little drone at around 1700-1800 rpm when picking up speed through the gears but nothing major. I'm very pleased with the result.

Blastin' Bob was running a special which may have expired, check with him to find out. Beyond that the only other way to get one cheaper is to wait for one to come up used for sale.

I've had the BB-6.1 resonator delete kit on my car for awhile now. LOVE the sound..
Low rumble at idle, at WOT ..You know you have a Badazz HEMI..
At normal cruise..sounds like it should sound from the factory-IMO
Take off the resonators, run it like that for a week or whatever time it takes for you to
decide if you want to go forward, or go another direction. I think you'll like the BB, I
know I do..LOL..even my girlfriend says it sounds good..THAT's Great..

Alot of SRT8 guys here... Sorry but I'm wondering if any of you have SRT8 coil springs if you lowered your SRT8... I'm looking for some to mildly lower my SRT Design... I know it's off subject, and appolagize, but thought one of you might want to sell your coils. Thanks.

That suitcase is a major choke point for the SRT exhaust. If I had a SRT 6.1, I would remove it ASAP. Why? Because it the same exact muffler as the 5.7L performance exhaust and that muffler is only 2.25" diameter piping, while the rest of the SRT 6.1 exhaust is 2.75". So you have exhaust flowing out the headers into 2.75" piping, then pinching down to 2.25" at the suitcase, then at the suitcase outlet, back into 2.75" piping to the resonators. Simply removing that suitcase should give you the largest improvement in exhaust flow for very little coin.
