Just had my 4'' Mufflex with spintech muffler installed yesterday with the matching 4'' merge and a 4'' badlanzhpe Cutout & Turndown assembly.

The sound is great IMO and it's alot quieter then the Dumped Single chamber I had in the Y-pipe. The seat of the pants feel has Improved but dyno numbers are soon to come to see if there is a real gain or not.










This was the sound before the mufflex with the flowmaster

Idle/Revs though the spintech, The quality is kinda crappy and I believe the car loaded up at the end, the rpms drop really really low and it wanted to die.

yea sounds better with the mufflex setup, more tame.

 

Mufflex does sound better. I like my exhaust loud, but i didn't like how that flowmaster sounded compared to the mufflex. Got any rev or WOT clips?

+1 i'd like to hear that thing WOT. Sounds amazing though, i love the spintech muffler, but i've only heard it through high flow cats (mine).

 

Sounds good, is that with the cutout closed? This is the setup that I've been wanting to do. How much did the whole setup cost, labor?

 

Thanks guys, I'll have to get some rev/WOT clips and that video is with the cutout closed!

 

sounds awsome cant wait to hear you rev it up a bit.

 

nice set up but that spintec is super heavy also dose not flo well.but you have cut out so flo not issue.

 

Is that a LT1 or LS1? It says 97 Z28 so I assume LT1 unless you did a swap. The LT1s had a better sound to the exhaust in my opinion!

 

It's a LS1 Car, Swap was done 2yrs ago. I will get some Rev clips, cutout clips and maybe some WOT clips.

 

Cutout Clips & Rev Clips through the spintech added!!!

 

What's the motor setup? Sounds good!

 

I like the way the spintech sounds. I just got a used spintech catback and have never heard it on a fbody.

 

does your rub or vibrate at all when you are driving?

 

Man that does sound good. I wish someone made a single 4" in/dual 3" out muffler other than spintech...

 

Damn, those are some huge lips on your rear wheels! Do you have a shortened axle? Your car sounds really good!

 

who did u buy it from i want that setup exactly my SLP loud mouth is crazy loud after going to my current setup

 

Thanks! My S60 was narrowed 4.5 inchs to get that dish.


I ordered the catback and Merge directly from Denny @ Mufflex. They opened up the Merge so the 4'' intermediate pipe slid into the other pipe.

 

What driveshaft loop is that? 4" merge? Thanks.

 

Magnaflow (12594) makes one, but it is 4" in on one side and dual 3" out on the other. I am thinking about getting it for a 2OTL look.
