Would you guys trust 16 year old thrush turbo mufflers for the break in? The ones on the car were relatively new when I parked it but it's been setting for 16 years idk what has got in it and built a home or died or something else in there. I'm just worried about them being blocked or something. I'm not worried so much about sound yet I just want a smooth uneventful breakin . I considered cutting them off and welding on some cheap glasspacks but dont really want to spend the money on a temporary muffler. Or I could just cut them off and weld a piece of pipe and straight pipe them. What do you guys think?
 
Thrush turbo would be good I think. You want it fairly quiet to hear for any strange noises before they get louder! LOL
 
Pour a little kerosene in them and light them on fire, after blowing them out with air.
That should evacuate any critters.

Maybe use some gas! Haha just kidding!! I know how to make and epic flame thrower with a air line and alcohol ask me how I know! Lol
 
No, no!
Slip the Thrush Turbos on real gental like, then mount a GoPro under the car, THEN let er RIP!
And show us the rat action in slow motion !
:lol:
 
Toss the entire system and buy a jegs mandrel bent kit, w/o mufflers..then buy 2 dynomax ultra flows.
16 years. I've had 14 yr old systems under use that looked like ****... sawsaw that crap out and have the pressure you're actually going to run it with when you tune it after break in, not those old restrictive vermin stuffed, acorn filled, rust dust blowing pieces of ****.

That's kinda what I was thinking too. The tailpipes are 21/4 I'd like to run 21/2 at some point i just dont have the money to redo the entire exhaust atm.

2-1/2 is what should be under the car for your mill.
 
I run borla XR-1 race mufflers. they are basically a glorified glass pack. It isn't loud unless you are on the go pedal. If you want to hear things during the break in, wear ear plugs. You'll hear everything.

I pressed the EZ button myself with a Jegs and Summit exhaust kit before. Well worth the price with minimal pipe cutting involved. Fit between both kits was excellent and even better considering there inexpensive pricing.

The first kit I purchased was from Jegs. It was the complete kit. A minor trim at the rear bumper was all that was needed. This is a ‘08 video;


The new kit is from Summit which also included mufflers.
I also have, but not installed the H pipe. That will wait for when the drive train is installed and otherwise, ready to rock.


The mufflers supplied with the kit neck down inside. So I went and purchased the Summit brand turbo mufflers that do not neck down inside. The sound difference can be heard somewhat in the video. As I pass the first supplied set of mufflers, you can hear the tin sound they have through the muffler body. The second set at the end have a more husky thump though not a 100% true sound to them as the first set has changed the note a good bit. Without the first set of mufflers up front, the second set looses the fart sound. A more authoritative deep pounding sound.

The H pipe when installed should knock out a few scant decibels but help overall in power without loosing the pipe to pipe pulse to much of the true dual exhaust set up. The X like shares the exhaust pulses so well that the exhaust sound is shared so well it looses that heavy thump that bounces from pipe to pipe like the old days. Up top in the RPMs of a WOT run, the X pipe just simply shreaks like a Banshee! (Really cool IMO!)

Nah , just the wasted time part.
Soon as he pulls the cob web stuffed 2 1/4 exhaust off and puts a 2 1/2 or 3", the idle speed will need reset, the tune all in all will need revised.
That's how back pressure works.

That said..
There is a bigger picture and most dont see it till they're faced with it.
