Expansion pipe finish...& performance??

I started w/M&G on my F1's and it didn't work too well here in SF (coastal, moist weather). I went w/ceramic coating and if I had to do it over again I would go nickel. Or, better yet get 'em made in stainless steel.

 

Dam SFO423, I was almost sold on the mop & glop. Even Gary said it gives good results. Going to do a bit more research before I decide. I like Chrome, but the unfinished look definitely gives that factory GP look. Don't think He'll do it but I am going to ask Gary if he'll stainless. I'll keep you'all posted.

Just keep in mind if you nickle or chrome the pipes, you'll have to polish them and smooth some welds.  You'll also need to reduce the diameter .020 (outside pipe, inside manifold) to accommodate the extra material.

I would do ceramic powder if you can.

I use m&g on mine and it works pretty well, it can scrape easily, so be careful handling them.

Use a smooth cotton t-shirt to apply or you might get fish eyes when it cures.  A sponge will be too streaky i think.

I've also seen this stuff by VHT-SP115.  Supposed to be a 1500 degree clear coat.

Anyone got any experience w/ this stuff?

The spec II pipes fit bolted right up w/ NO problems.   They perform really well and I agree, there wouldn't be much difference in performance over the F1...you save 100 bucks with the classics (the skinny stinger you see when you remove the silencer core....  Ron (RB Designs) checked his porting specs with Gary and Gary said that they would work w/ his pipes.  you always want to match the engine to the pipes for best performance (from what I've read)...head mods, porting and squish were all ok.\

While we are on the performance subject,  what's the best packing to use when repacking the stinger end?

   Matt Shearer-Give him a call. Builds banshee pipes- a lot of them. Maybe you heard of those. Dyno on premisies, many drag records,titles. He don't plate or ceramic coat himself and don't make $ on,  or care -what you do with his pipes. If ceramic coated pipes made more power for example you'd think Mick Doohan's old Honda's,and Rossi's 2 strokes would have been ceramic coated[it's not very new] and your's would be too. Also, do you think your 2010 spec 2 classic's are any different than say.... a 2006  set? There's about 4-5 changes since the 70's. Does  Gary himself tell you  his c. coated pipes make more Hp?  Sorry, you're killing me all over again.  And they way you claim "reality is"  is over the top an prompted my rant-sorry.
