Righto fellows, going to get a new exhaust put on my smurf, was wondering what size to go for whether 3 inch or 2 1/2. its going to be whatever size it is from the turbo right to the end with a "turbo" muffler. Would like to go 3" but dont want it droney on open road driving, any one got a 3" on there 1kz?
Cheers

Know very little about it but have heard that going larger than 2.5" is not gaining anything with those - but would want to confirm that.

Haven't heard of anyone having heating issues with a 2.5"
