I have an lq9 with 1 3/4 tsp lt and I'm going to install heads and cam and imvwanting to know how to quiet down a lot I have straight pipes right now with 3" and with a cam its going to be noticeable.
Anyone know how to make it more quiet To where it is barely noticeable to none at all,I'm planning on putting cut outs so I can have it breathing and close them when I'm just idiling or cruising it

 

A big magnaflow muffler will do the trick.

 

Really? That all I need

 

Yeah I have a single 22" body magnaflow 3" center in and out, dumped before the axle no cats and its quiet untill you really get on it.

 

A muffler...

 

I have a hard time believing that this post is even serious...

yes a muffler will quiet down your exhaust. Depending on the size of the cam it will still lope at idle though... but a muffler helps to mask it.

 

Agreed...

 

 

LMAO

Just put your cutouts directly on the header collectors. It will breathe fire with the Cutouts open, and get REALLY quiet when you close them.
