After reviewing different intakes and HP gains I went with a typhoon aluminum intake and larger throttle body. Looks very nice and provides a substantial amount of HP but does have its disadvantages in regards to weight. It does sit slightly higher and does weight more over the stock plastic LS1 intake, I would probably not recommend this for anyone else who is considering the swap. It was a very tight fit and makes zero clearance for the throttle body against the back firewall.
For the exhaust I went with the manifold from a ZO6 vette as I really liked the HP gains and found a good deal on Fleabay that someone had modified for a Chevy S10 conversion but did not fit. I had talked it over with Steve at RH and since it had not been done before we were unsure if there would clearance problems. Lucky enough for me that when everything was bolted up and put in the car there were no problems
For sure it will need a good welder and some nice mandrel pipes to be finished but I do not foresee any issues.
