Not sure I like it. But here is a 1 7/8 long tube header w/3" Mufflex Y pipe into a 4" Mufflex and Dynomax muffler w/single 4" out.

 

Sounds mean to me!
I like it.

 

Sure it sounds good under load in person

 

It's actually no louder than the Ultra 40 I had on it. In fact I was kind of disappointed. lol

 

Which model Dynomax is that? I kind of want to ditch my Spintech. This seems like a decent option.

 

17225 Dynomax.

What spintech do you have? I have a Ultra 40 4" single exit I took off this. It sounded bad ***. It's like new. Trade you for the spintech??

 

Sounds pissed off! I like it.

 

I'm not sure if it has a part number on it. It's the one that comes with the 4" Mufflex kit. Single exit on the left, 4" in and out. I can't say that I really recommend it. I had to weld it on to keep it from blowing itself off at anything over 3000 RPM, which to me says there's substantial backpressure. Now it tries to come apart at the bend that goes over the axle from time to time.

 

OK, well if your interested in the Flowmaster, it came with the 4" mufflex kit, same thing, one in/out, I'd take $100 plus the ride.

 

Sounds good. What is making sound so good? What's under the hood?

 

379 cid of old school 23º grunt. Baddest 205cc CNC heads on the planet.

 

Looks killer. Love the coil conversion as well. What intake is that? That doesn't look normal TPI to me?

 

Motown with a Nitrous Outlet elbow.

 

I should have been more specific. I meant the air intake. The plenum looks so much taller than normal TPI air intake.

 

I cut and sectioned it. There is a thread under Fabrication.

 

Here's the link.

I've always wanted to do this mod but kept it in reserve as the internet opinion was that the TPI panel style filters didn't provide enough capacity for serious HP. It wasn't until Chad did some real world testing that I'm back on board. And considering what he does for a living, I'm inclined to accept his results.

 

Thing sounds ROWDY!

 

It is well done for sure. I would like to explore this further for my LS swap. Not sure I am in love with the traditional 4" intake pipe.

 

I've seen plenty of the big pipes with the K&N cone stuffed on the end but for the most part they're picking up air from under the hood no matter where you place them. The TPI air filter case is the real deal for a CAI. And the possibility of adding a ram air package just makes it better.

 

Agreed. My plan now is to run a filter in front of the tire (go right through the floor where the EVAP used to be). The TPI style has me intrigued.

 

Tpi style as chad has done plus duct work to the grille to create ram air is the best setup possible besides forced induction

 

If it hadn't been for Chad's report on the filters, it's not something I would have pursued. I bought a cowl hood specifically to get cold air to the carb via a sealed pan and open element air filter. With this latest development, I think I have a change in plans. I've got a couple of TPI filter cases to work with. It remains to be seen whether it'll fit under the glass hood though. The bulkhead across the front isn't of the OEM design. And then's there's the adaptation of the 4" pipe to the carb itself to consider as well.

 

Also found out how much converter I have, lol.. I lifted a little at the top of the shift because a car was coming, then thought screw it. After it shifted, I went a little before taking my foot out of it. Need to find a chassis dyno close.
