Well I've decided to get rid of the old megamax. It's starting to get really beat-up and I don't like having to run the disks on it. I've had my eye on the T4 muffler from Pro Circuit. I like their pipes for MX bikes, top notch quality and they're in my price range, $189.99 from most places. I just have 2 questions:
1)Do they perform as good as all the other new generation straight-thru mufflers?
2)Do they have a good fit? That's one thing I have to say for the megamax, it fit real nice.
Your opinion would be appreciated. Thank You.

 

I just got one and i hope to have it on by the weekend, I'll let you know how it is!

 

I've been racing with mine for about 3 months now. I've rode two of my friends, one with the Big Gun and one with the Noleen. Mine seems to run better than the Big Gun on top and equal on the bottom. It runs better than the Noleen everywhere.

 

A guy I ride with has the slip on Pro Circuit on his 400. He said it really woke it up. I have rode it and I think it feels very strong also. It is his only mod.

I put a T-4 on my ex and it is great. I love the adjustible end caps. It gave it more power all the way around and it is easy to tune up for certain riding conditions. You would be happy if you got one.
