as thinking of getting new exhaust, custom build snakes head down pipe with middle section and dragger style b/b. was thinking about getting it all 4 inch with no cats. u think this is good idea or is 4 inch too big

 

Boost creep?

...and small animals hibernating in there.

 

Gaz, please don't call the guy a creep.

Anyway, don't think there's much to be gained by going beyond 3", but if you're after noise and appearance, go for it (not for me though).

 

think i will stick to 3 inch 4 inch too noisey i think
