Mufflex 4 inch Exhaust on LS Swapped third gen Camaro.

[@accordv6er]

Had a buddy running a diesel 4" exhaust on his supercharged LS Sierra... One of the best sounding and cleanest, simplest setups I've heard. Love the look and sound

[@thedudeman9629]

Goodness gracious bro, what a beautiful machine.

[@Brandon-LSX]

Thank you appreciate that.

[@shaquillefielder2518]

Life saver I’m currently I the starting stages of rebuilding my L92 6.2 and was literally spit balling the numbers at the tire and you gave me all the confidence I needed

[@shaquillefielder2518]

Throwing it in a 84 z28 ttop

The 6.2 is a awesome platform. With a nice cam and tune they make 450 to the wheel easily.

Sweet car man! Mufflex sounds great I had it on my 96 z28 over 20 years ago but I had the flowmaster 50 series muffler they offered then. I remember it was super deep and had a nice pop to it on deceleration.

Same here man, my LT1 loved that mufflex system especially when I put it on the bottle!

[@nikesbcollector23]

Awesome finally came across a video of this proven exhaust that isn’t 10 years old and 360p lol. Has me even more excited now to throw in on my 408 trans am. Let’s see some WOT pulls and fly bys with this exhaust!

Thanks I remember looking for current videos before I purchase it and there was none lol. Definitely in the works for some wot and fly by this exhaust sounds pretty awesome.

[@robertwilkerson1720]

The new exhaust sounds meaner! I’d like to see ur next dyno sheet. Btw I notice u have new EVERYTHING underneath that car and looks super clean. Wished mine looked half that good. I got a lot of catching up to do ha.

[@Brandon-LSX]

Thanks Man. Yes it definitely sounds alot meaner. I'll be doing a future dyno run to see what it's putting down with the bigger exhaust hopefully it will be 450+ to the wheels.

3rd gens should never have pipes sticking out from the back..some like it..some dont..Gm always tucked them up under the car... Nice looking Camaro.. Iv had mine for 30 years now..

[@Brandon-LSX]

Thanks ya its definitely personal preference but I do like it alot better without pipes. Gives it a nice clean look.

[@thecitiots]

Mufflex will fit with stock panhard bar. When I bought the kit it came with all ban clamps which is nice cause I've had it in and out of the car many times. Love the 4inch

[@Brandon-LSX]

It will fit bit definitely doesn't leave you much wiggle room. I thought I would miss the dual pipes but I don't. The sounds is amazing and the car looks cleaner with the muffler tucked.

[@thecitiots]

@@Brandon-LSX I agree it's a tight fit but well worth it.

[@TransAmMazing]

A tune would unlock more power. The self tuning capabilities of the fitech is cool but custom tuning would really unleash the beast

[@Brandon-LSX]

I agree only bad part is not many people will tune the fitech system. I've had a remote tune done that's about it. I've been trying to learn some to make adjustments but it's definitely alot to figure out.

What trans crossmember are u running?

I'm running the hawks max clearance crossmember for the t56.

[@Bbdrew]

pretty sure you might of chose my exhaust for me. I have a cammed LS1 with a t56 magnum & 9" that I have running good I finally need to figure out its exhaust. Can you tell me what kind of crossmember you use? it seems like all the nice setups use Hooker Blackheart for the exhaust clearance, but it almost looks like you have one of the BMR/UMI ones? I have a BMR T56 crossmember. I bought it when I first started my swap and was too broke for the Hooker and now I'm trying to figure out if it's going to be better before I do exhaust to bite the bullet and get the hooker crossmember and try to sell my BMR piece. If you're using one of the BMR/UMI style ones do you have any issue with exhaust clearance/scraping?

[@Hailey_WhiteRaven]

Honestly I would have left it like before...but i would have eliminated the muffler all together place a tee to run out the dual pipes and you would get that throaty sound...on my 88 iroc I removed the catalytic and the muffler as well and my 5.7 tpi ROARSSSSS

[@richardernst8857]

The sound doesn’t sound too bad but there’s sooo many other things I don’t like about it one is the single pipe that doesn’t even come out the back needs true dual exhaust and what’s up with the Y pipe that goes into one seriously hahaha I seen the header on one side so why didn’t you straight pipe it all the way to the back and I love flow master 10’s I have two one on each side of my cars just behind the rear axle with cannons coming out the back and they roar like Beasts Challenger RT Hemi and a Z28 Camaro

[@Brandon-LSX]

Well the dyno doesn't lie. I absolutely over powered the single 3 inch exhaust. You've got to remember wheel horse power doesn't matter with exhaust it's crank HP. My engine is making roughly 530-540 crank hp. A single 3 inch can only handle about 370-400hp. That's why I over powered it. A little research could back up it up.
