L99 Stalled guys - What exhaust?

I've got the stall in now along with a cam, LT's, HF's, xpipe and JBA axels. The sound is very deafening and I need something that won't attract the CHP, 3 miles away. Anyone running a similar engine setup? What exhaust are you running? How quiet is it?

Get a street series axle-back. Magnaflow, flowmaster, and not sure about others. I know most of their exhausts can be quiet.

I'm running into the same issue with my setup. KB, cat-less LT's, and Borla ATAK...My record stands as 6 pull overs by the PD this summer.

I'm having a custom exhaust built for me though.

Mine is 3 since the cam, which was done in June-ish? With this stall I gotta give it a little more gas and that attracts the po-po REAL quick...

Its a 3000 stall. It may sound good but not to the CHP or SDPD.

Borla Touring. Check my videos to see if you like. All you need to do is switch out the axle-back.

3 inch Magnaflow really calms down the RAP.

SLP

I think SLPs are now owned by Magnaflow, but they sound really great and not too loud. I'm sure it depends on the rest of the exhaust system....like headers and cats.

Magnaflow Street catback is the quietest catback on the market. I run this catback on my car with Kooks long tubes. Its the perfect setup for someone trying to keep the noise level in check.

The guys at the shop tell me its the best sounding setup (long tubes + Magnaflow Street) they've heard mostly because its not too loud, but still sounds great.

Without long tubes the Magnaflow street is ridiculously quiet.

I have never had a TC... is the TC keeping you at a higher RPMs and making the car sound as if it is near WOT or something?

I am deciding if I actually want one, but I may just wait for the cam swap.

A higher stall torque converter will multiply the torque of your engine to put more power and torque to the tires! The high stall torque converter will "slip" the engine into a higher rpm range where there is more torque and horsepower. This will make your car haul ass!

Yea, I got that portion of it... I guess I never thought the basics of higher RPM, higher dB volume..

The only thing keeping me from doing this is the MPG hit.

In my case, I've having to ramp up to about 2.5k to get moving. Couple that with my bolts and cam and the cops come running. It was loud enough at near WOT without the stall, now it's crazy loud.

Yea, I have the basic bolt ons w/out the cam yet.. so it would be pretty loud as well even before the cam.

I guess I really just need to take a ride in one with a stall just to see...

I have a Borla Touring catback exhaust with my cammed car with LTs. I also put on electric cutouts (I have no cats) so I can have the "stupid loud" if I want it. Here is a video. We open the cutouts about 30 seconds in. The cam and headers add plenty of sound, so I went with Borla's quietest exhaust which sound perfect to me. Not too loud, but nice and growly.

I had the borla s type after the cam headers, it was annoying at highway speeds. I went with the 3" kooks and it sounds great.

The thing I discovered is that a cam made the car a lot louder than it was even with LT headers.

Hmm, don't know if I want to go that much louder or not after headers lol... it got great volume now. I imagine with a stall and cam it could get pretty irritating for neighbors.

How much volume increase did you see? I knew the lope was distinct and I love the Borla tone, but TOO much louder... hmmm

I have kooks with the 2.5 right now, didn't realize the 3 inch might actually help drum some of the volume.
