Finally Got My Custom 2.5 cat-back done

**The_Evil_Demon** · 4-28-07, 18:34

Got my cat-back done. 2.5 from the headers all the way back for $60 bucks from my friend who owns a exhaust shop. Maybe i could talk him into mass production off these for $100 and i'd keep $40 of it..lol I still have the stock muffler cause i haven't decieded on 1 yet. He said he can install the magnaflow with Real Corvette tips on the back for $150. Muffler alone is probally that much. The car pulls stronger than ever. And on top of that i did the seafoam treatment and switched to synthetic blend oil. From the butt dyno i'd estimate an extra 15whp. Can switching to synthetic really improve the car that much, Thats insane. I'll get some pics off the exhaust up when i get time. Whats the best muffler for our cars sound wise. i want a nice sound not raspy rice sound

a borla sounds good imo

**Mx6Ownage** · 4-28-07, 20:29

different oil = hp.... i need to get some of that! Best of luck with that. Hopefully you have no leaks after switching to synthetic right after the seafoam treatment. Borla does sound nice, but there are lots of different mufflers out there.

15whp i doubt, your torque curve is different for sure, this is why you feel like your going faster, 5-10max.

Good to hear the DE is running well!

The dual tip Magnaflow I have sounds great, nice and deep.

Can you post some pics of your muffler. The magna flow he showed me had 1 inlet and 1 offset outlet both 2.5' wasn't polished or anything. I can hear a slight raspyness with my stock muffler. will the magnaflow change that? Forgot to add i don't have a cat on there so it might be louder than i want it to be. I like how quiet it 's now just want a little more growl.

raced a 93 prelude over the weekend and pulled on him. I doubt i would've won before getting this cat back done and the oil.

Oh damn, sorry I never checked back to this thread. Here's the only pic I have of it for now:

If you're looking for something quiet, check this out: http://www.mx6.com/forums/2g-mx6-oth...e-exhaust.html (My New 'Quiet' Performance Exhaust)

I've heard it in person, and it actually is quiet at normal throttle, but definitely noticeable when gunned.

Hehe... I love it when people cite my exhaust.

Thanks BShark! Karma for you (if it'll let me, its been a bitch about that of late!) Damn! No Karma, stupid Karma limiter.

So i guess if i want the low growl I'll need a hi- flow cat and a resonator huh ? that sucks. Guess i'll just get the mangaflow and if it's too loud the i'll get Hi flow cat " friend has a slp 1 he bought for his 04 gtp" for $35 And slap a glasspack underneath

**93speedstud6** · 5-8-07, 17:27

60 dollars eh? i would like to hear more on this, cuz piping is piping in my opinion, unless someone can correct me. and if i can get an exhaust for 100, over 500, ill take it.

**Adaman** · 5-9-07, 1:53

bshark, I love the muffler. I'm thinking of getting it, but i also like the borla wailtail muffler though...

**Green Alien** · 5-9-07, 8:13

Not sure if he has a mandrel bender. These are crush bent pipes 2.5' dia. His shops in decatur Indiana " Bodies Performance exhaust" The muffler i'm buying looks like the one you have bshark except it only has 1 outlet on it.
