Default My car is too quiet..Need advice..

I have Npi 4.6 with a pi head swap stage 2 cams with long tubes and mac x-pipe and flows with stock tail pipes..When at idle the car is too quiet..Thinking of cutting the tail pipes off..I like the sound of the car when driving just wish it was louder..Any advice.

Are there cats (catalytic converters) on the mid pipe, or is it an O/R mid pipe? If it has cats, consider an off road mid pipe, or swap mufflers like ******** suggested.

Go O/R X + Borla Stingers if you want loud or O/R X + Magnaflow Magnapacks!

You have stage 2 cams, and it's to quiet at idle? Wow...that must be a very different grind then.

Try something like SLP 1's, Dynomax race bullets, or SSS Terminators. These are some of the loudest straight through mufflers you can get. Paired up with a o/r mid pipe, it will be crazy loud.

If that doesn't do it for you, then get more aggressive cams...lol.

Apparently suggesting you remove a coil and let it run on 7 cylinders gets your post removed. haha. That would definitely give it a throatier idle ...no sense of humor

I used to run magnapacks and a vrs o/r xpipe and it was destroying my hearing on the highway and would get police attention driving normal around town. I switched the xpipe out for a stock h with cutouts welded into the end of them. I had electronic covers for them but the motors give out anytime you hit them (poor design by the manufacturer) - it gave me the option of being loud or quiet whenever convenient. I still have plates that i can put on manually so I really only run them closed on long highway drives.

Everyone that hears it compliments it and it's got a damn nice idle to it. Depending on what you use the car for, this might be an option. With the long tubes, you should be able to weld them into the xpipe without cats and not worry about flashback into the head (partially why I swapped the midpipe out before getting them welded in).

Good luck.

go slp lm1's or borla stingers. No way you will think your car is to quiet after installing either of those mufflers
