SIP or BGM Exhaust?

[Lamaddict]

I've standard Rally 200 and I'm looking for a new, standard looking exhaust. I did have a BGM exhaust on a P200 once and it seemed good but I've heard about the SIP ones, any thoughts?

In short: more peak power and over-rev from BGM but better ground clearance and bottom end power from the SIP Road 2.0.

Yes, I've just done some more web searching and they seem pretty evenly matched. The SIP ones seem cheaper which is always a bouns.

I have the sip road 2 pipe on me otherwise standard Rally 200 (6v femsa) - its a nice torquey pipe which gives you a bit more bottom end & mid range grunt over standard.... upped the main jet to 122 & it runs sweet.

just yesterday late on put a sip road on my mildly tuned p200 to see what its like against the SIP performer ive been running for a long time - just want to see what its like mid range.

I got a brand new chrome one off ebay (private seller) for a great price so though I`d give it a go - surprised how loud and tinny it sounds (sounds sh#te to be honest) against the painted ones - the sip performer is quieter !

will report back when its out on the road !

I ended up ordering a SIP Road 2. Hopefully, it will be better all rounder than the BGM one.

Well, I put the SIP 2 Road onto my standard Rally 200. Put a 122 jet big it seemed a bit too much, so put a 120 which seems not quite enough, wish there was a 121. I had a BGM on a P200 and it seemed to make that run better. I'm thinking the BGM might have been a better bet but they are a lot more expensive. I might put on a better cylinder head and see how that goes, I don't what to change the barrel.

What better head are you thinking of to use on a standard cylinder?

Try the 120 main but with a 150 or 140 air.
