SLP Loudmouth’s Arrived!

[zbecker13]

Cutouts will make the truck raspy? I have some QTP on order and if that's the case I'm canceling them. I can't stand the rasp... had at 16 Mustang GT and put a system on to only should like shit. Do not want to hack up mine for that...

To be fair, I haven't heard anything about the cutouts. This is what I have heard about taking thr stock resonators out and just putting in more tubing.

Another happy SLP Loudmouth owner. Ordered them from @SRG_Joe. Great communication and arrived quickly. At idle and cruising speeds, there’s not a tremendous difference. I’ve not noticed any drone. When you romp on it, it’s 100% obvious something has changed. As others have said, this is the way they should have shipped from the factory.

Thank you!

I just had mine installed this AM by Macs Custom Exhaust. Initial impressions are positive. As many have stated, there's a slightly louder idle, but it doesn't drown out any music or conversations. There's a noticeable difference in sound, even at 1/2 throttle, with a much more pronounced bellow on the low end. No highway driving yet, but I'll be sure to update accordingly.

Another thanks to @SRG_Joe for the goods!

If anyone in the Charlotte NC area wants to hear a TRX with the SLPs on just let me know. We did mine and I could not be happier. I've heard a TRX with the Borla set up on it, and while it does sound a little bit better, it does not sound over 1000 dollars worth of better.

I’m trying to decide between the two.

Man I wish you were in AZ and I would let you drive my truck in a second to see for yourself. Hell, it's the least I could do since your YT vids and posts led to me buying the SLPs which I don't regret one bit.

While I'm sure I'm experiencing a bit of a honeymoon phase, I made this purchase with skepticism and I just can't poke a hole in this exhaust right now (except for the damn tips not lining up)

So you definitely recommend the Borla over SLP? I’m not a fan of just straight pipe either. I’m more of an “exhaust system” guy. I can definitely tell a difference in sound when there is just a muffler delete.

I loved the SLPs, but don't regret the Borla one bit. To me, it was money well spent but I have always had an odd obsession with getting exhaust exactly where I want it. To those that don't share the same preoccupation with sound, the SLPs deliver no doubt.

I would like to hear it. How much louder was the Borla than the SLP?

 

[TheMuffinOfEvil]

I would say they're pretty close in volume level overall, the SLP loudmouth are definitely louder on cold start in my opinion. I'll be in The ballantyne area of Charlotte Friday at lunch time. Feel free to shoot me a private message if you actually want to meet up and hear them.

Got mine installed last week, absolutely money well spent! Cant imagine this beast without them now.

 

[hobbez84]

I finally got a few hours on the highway, managed to do a short trip from VA to PA and back. No issues while cruising on auto. If there is any additional drone, it was imperceptible to my ears.

 

[Corporate_Thug]

I got mine installed last weekend and couldn’t be happier! It is loud when you want it to be, but not obnoxious if you don’t.....but when you stomp the gas....

Absolutely worth the money and how it should have sounded from the factory!

Can’t make tomorrow (I’m an hour away) but might try to come check it out in the next couple weeks if possible. Thanks

Read through this entire thread. Researching both Borla and SLP. Like everything that has already been said...looking for a premium sound but for the price delta...seems hard to rationalize the extra money. There is something about having the full exhaust that I like though. Guess reading through this didn't help me one damn bit!

Nag man I’m the same way. I’m between Borla, awe and corsa. Maybe slp but everyone either sways off course or has way different opinions

 

[Lord Tyranus]

SLP loudmouths are excellent deeper idle and when you get on the gas wow incredible loud sound no drone. Cheap enough to rationalize a full system down the road if you are one of the few that want a refined sound. Get the slp loudmouths you won't be disappointed.

 

[Steiger]

Is there much difference in cold start volume of SLP Loudmouths vs Stock? I have some great neighbors and don’t want to piss them off. I would get electric cutouts but I hear they can be problematic

 

[Lord Tyranus]

It is louder at cold start but any exhaust will be the engine rpm is high to heat up the oil and circulate it in the engine after a while the engine rpms drop down and it is not obnoxious just deeper and let's you know the exhaust is no longer stock. The best thing about the SLP Loudmouths is full throttle will be incredibly louder all cruising rpms are slightly louder than stock the real difference is when you get on it.
