Those short box mufflers are pretty loud and may not flow that great.

I am running 17749 Dynomax (Formerly "Hemi") mufflers on that setup shown - X pipe and full tailpipes. Not as quiet but a hell of a lot better than Dronemasters on sounds and flow.

Before I seen your reply I just viewed the youtube video. I do like the sound and not too loud. I may just piece together everything, except the mufflers, from ramairrestoration, and possibly use the 17749's.

Going to do more research before anything is bought and paid for.

Thanks for the info.

Were I to do your exhaust I would use 2-1/4" mandrel pipe, no X crossover and the transverse case Dynomax.

Why smaller pipe? Don't really need 2-1/2", and using RA3 manifold with 2-1/2" downpipes is a PITA. Fitment is far easier with smaller pipes along with ground clearance, and when I went from 2-1/4" to 2-1/2" on my Lemans with the same type of mufflers it got MUCH louder. To me, all a loud exhaust does is call attention to hoonish action to the guys with blue lights.

I would maybe even stick with the logs - on lower HP apps they do not lose much power and are considerably lighter and cheaper.

I have the original exhaust manifolds and they're in good shape.

Thanks for the input.

For now.....going with the Ram Air manifolds, down pipes, x pipe and end pipes. Still working on the muffles/resonators.

Rebuilding the BW Super T-10 4 speed shifter. One of the insulator pads is coming out at the bottom of the handle so decided it was necessary. Parts will be here by end of week.

Pretty straightforward job with the shifter. I did mine a few years ago. Are you taking the carrier apart as well?

wheels78ta · « **Reply #208 on:** February 04, 2024, 08:11:29 PM »

Yes....everything will be done. The kit is a complete rebuild including the springs and pads.

wheels78ta · « **Reply #209 on:** February 06, 2024, 02:27:43 PM »

Watched a few videos to work on the shifter. This guy does the break down of the shifter and assembly. He made his own tools and bracket to work on the carrier. I have some steel scrap that I used for the bracket and bought a couple of putty knives to copy what he did. Worked out great.

To go along with the Pypes exhaust system.....

Motor and tranny are installed. Tranny is being held up on a jack stand waiting for the crossmember to go in. Maybe tomorrow.

All I can say is............Wow.

The excitement continues.

That was a giant load off my mind and body to get those installed. The trans crossmember is now in along with the drive shaft.

But.......this project will be delayed for a few days. Our 2005 Suburban 2500 4x4 just toasted the transfer case. After hearing some clacking and grinding noise......I checked the fluid level and it was almost completely gone. Now I get to remove the transfer case and rebuild it while it's on jack stands. I thank the Federal Government for their poor maintenance.

This Suburban was part of a fleet for the FBI. I guess I expected more from them for the up keep but I was "WRONG". Oh well. I accept the challenge. Bring it.

More pics soon.

Willie,

Congrats on your TA progress, looks beautiful. I am a little old fashioned and like seeing a Pontiac engine.

Looks great! I am at the Pypes install on my car right now, still waiting for additional parts to show up!

wheels78ta · « **Reply #218 on:** September 08, 2024, 05:34:02 PM »

Small update...................

Got some parts installed on the engine..............

And coming in the next few days........A complete write-up and pics on the tilt steering column. It will start with the steering wheel removed..... all the way down to the to those 4 bolts that tighten up a loose column.

Finally got some new tires

255/60 for the rear

Great project! Nothing like installing a freshly painted engine with accessories. Can't wait to hear about the first time turning the key!

roadking77 · « **Reply #223 on:** October 28, 2024, 06:28:07 AM »

Where did you get the tires from?

I have realized I will be needing new rubber for my car soon. I started looking around and am not sure what I want to get. I think it was the ones that you got that seemed to be the same price regardless of who was selling them. I think Walmart even had them. I usually to to tire rack dot com and they had quite a few choices with prices all over the place.

Steve B · « **Reply #224 on:** October 28, 2024, 02:07:09 PM »

Hey Kerry. I bought BF Goodrich's too and bought them from Discount Tire. What made this worth mentioning was the fact they price match. I found them on another website at a considerably lower price per tire(like $30 or so less). I submitted the online form with the proper documentation and they had no problem matching the price. They were really nice and took care of me while I was there getting them installed. Good luck with whatever you decide to do.

wheels78ta · « **Reply #226 on:** October 28, 2024, 05:56:33 PM »

They had these sets of two on ebay for $417.98 by Discount Tire. I had them in my watch list for about 2 weeks and they offered me the sets for $397.08. A savings of $10.46 for each tire. Free Shipping....The 255/60s were delivered the next day and the 245/60s the day after that.

255/60 date codes are 3rd week of July 2024

245/60 date codes are 4th week of Dec 2023

Exhaust is almost completed.

The only thing left to do is work on the hangers near the tips.

wheels78ta · « **Reply #228 on:** November 15, 2024, 01:29:00 PM »

The pypes tips are not even but I'll trim those down.

wheels78ta · « **Reply #229 on:** November 15, 2024, 01:34:50 PM »

Found a set of Chastain Shadow rear window louvers.

They are in great shape except for the locks.

One lock works but the section for the key is wallered out. The other lock is a homemade job made out of metal.

I have a plastic block that I'm going to use and attempt to make a new set of locks out of. Dremel tool with routing bits should do the job.

roadking77 · « **Reply #230 on:** November 18, 2024, 07:44:33 AM »

When I put the last section on my exhaust the dr side went in no problem, I had some issues with the fitment at the pass side. I did not notice my tips being out of alignment, I will have to double check now

Nice louver. I saw one at Hershey a couple of years ago new in the box, the guy wanted something like $100. I had no interest so I passed it up. Wish I had bought it after seeing some of the prices those things get.

I bought the louvers, from Restore a Muscle Car, for $450. They came off a 1976 Trans Am. There is an identical set on ebay for $975. They are not cheap and usually the locks are missing or destroyed.

This is one of Pypes splitters (not mine). Notice how the tubes are cut across at the bottom. Flat line.

The ones that came in the Pypes exhaust kit for the Y88 are uneven.

I know they're not cheap but they were the least expensive that I could find. I had to do some cutting and welding to get the back section of the exhaust to fit right. I made a bracket for those hangers because that part of the exhaust is lower after i removed some of the height and bend.

wheels78ta · « **Reply #236 on:** November 20, 2024, 09:12:26 PM »

The exhaust is now complete. Now I can concentrate on getting some gauges hooked up.....starter installed......battery installed.....radiator installed.....etc.......and get the engine started.

I decided not to trim the exhaust tips. They actually look good after welding them to the pipes.
